Just a few short short weeks ago things weren’t looking too hopeful for our summer butterflies; the cold, damp start to the season had kept their numbers low and every sighting of any species was gratefully received and shared on social media. With many species already in decline, the predictions for the success of this year’s summer broods were edging on pessimistic and on many days, when out on walks I didn’t see a single one. Half-way through this month, a guided ‘Butterfly Walk’ was scheduled by a friend that regularly records the butterfly transect around Bryn Euryn, the limestone hill in North Wales which is at the centre of my ‘patch’. In preparation he’d done a recce the day before and his sightings were so few that he put out a warning that evening suggesting people may want to postpone the event and try again in a week or two! No-one cancelled, probably as most of are of an age where we’re not constantly checking our emails or social media sites, and about 20 of us gathered as arranged. Perhaps we were also a little giddy with the excitement of our very recent release from some of our Covid 19 restrictions (Wales has been a tad more cautious than England), and this was the first time we’d been allowed to meet up outside of Zoom since lockdown began. So in the spirit of ‘mad dogs and English/Welsh men and women’, we set off on this boiling hot Sunday afternoon (the beginning of the heatwave) to walk up to the top of the hill, 430 feet (131m) closer to the sun in the hope there’d be at least a few butterflies putting on a show for us.

Long grass on the cliff-edge providing perfect habitat for meadow butterflies

Of course it was well worth the effort, or I wouldn’t be mentioning it; in the space of 24 hours the butterfly species count had magically rocketed from practically zero to most of those we’d expect to see here on a good day at this time of year, plus day-flying moths The count for each species wasn’t high, but the majority of those we saw were fresh and all were highly mobile and in a group that size, numbers of pairs of eyes meant we didn’t miss seeing much. But the best part was watching the effect these particular insects have on people of all ages; some excitedly enjoyed the first sightings of rapid-flying Dark Green Fritillaries while others crouched down around a plant to witness the mating of a pair of Small Skippers. All captivated by the fluttering of wings and for a few magical moments, completely absorbed and transported into another dimension. Butterfly chasing should definitely be put on prescription!

Although I’d thoroughly enjoyed the company and butterfly sightings seen by the group, I’d missed photographing the fabulous-but-flighty Fritillaries, so as the hot weather seemed to be holding, I wanted to go around again at my usual meandering speed and a couple of days later I set off to see if I could fill in the gaps. This time I wandered up through the woods where the paths and trails are shaded and it’s a pleasant degree or two cooler than out on the open hillside, which surely has to be one of the best reasons for planting more trees in a warming climate.

A lovely fresh Comma and its shadow were a great start to my walk

Woodland paths are edged with False Brome grass

Now the tree canopy is more or less closed and limiting the light reaching the ground, flowering plants are scarce and as the earth dries out any that aren’t designed to cope quickly wilt. Built to withstand such conditions, one exception is Wood Sage, whose flowers seem particularly suited to Common Carder bees. Nipplewort, an annual plant with tiny yellow flowers and slim wiry stems always seems to find a few agreeable spots along these paths too.

As always I stopped at the fence on the woodland boundary to look out over the meadow on the other side. The long grass was cut on a mild, sunny day back in January this year, which at the time I remember thinking seemed like a strange time to be doing that, but it doesn’t seem to have mattered as now it’s grown tall again and I could see there’s also Hogweed and Ragwort in flower and it’s full of Knapweed in bud. I could also see it was alive with butterflies – mostly Meadow Browns as far as I could see, which was a good sign there would be more to see in more accessible places higher up. There were clearly other insects about too – my photo was ‘bombed’ by what could be a wasp or maybe a hoverfly!

Stepping onto the Woodland Trail that circuits the Nature Reserve it was hot – too hot now for insects such as hoverflies that would all be hiding away under leaves or on tree branches. Birds are mostly beginning a ‘time-out’ in which to rest after a busy breeding season and to moult their old feathers and grow new ones, so it was very quiet. The total lack of a breeze was even keeping down the ever-present traffic noise from the valley below.

Leaving the woods behind I joined the Summit Trail, more or less at the point where we’d begun the butterfly transect on Sunday. The small field here used to have a good patch of long flowery grass at this lower end, but perhaps due to more trampling and changes in the weather patterns, it’s not as good as it used to be for butterflies. Today there were a Small Skipper and a few Meadow Browns flitting about in the grass, but far more of the latter around the field edges where there is scrubby vegetation with low bushes of bramble and gorse. I counted to roughly 30, all busily chasing about low in the grass and around the brambles, with none settling for even a quick snap. The wildflowers are a bit sparse too, some Lady’s Bedstraw, a scattering of Rockrose, a few clumps of Keeled Garlic and the odd Harebell were all there was to see. The huge spread of Hemp Agrimony is just beginning to open its flowers and on the opposite side of the field the Burnet Roses have a good crop of hips; red now, but they’ll ultimately ripen to black. One of my favourite sights now are the feathery globes of Goat’s-beard that stand like little beacons in the shorter grass.

From the open field the trail goes up through the woods again, so there’s another short break from the heat, although the slope is steep. At the top is the clifftop with the long grass and scrubby vegetation pictured at the beginning of the post, and it was here that during the last two days, butterfly numbers had increased the most dramatically. Where there had been maybe 20 or so on Sunday, now there were more than I could have counted of Meadow Browns, a good number of Gatekeepers, lots of little Small Heaths, several Small Skippers, one or two Brown Argus, a Grayling and possibly even a Dingy Skipper. Standing out amongst the crowd of brown and orange butterflies were dramatic red and black 6-spot Burnet moths. All of these species are dependent on tall grasses as food plants for their caterpillars and as adults they take nectar from flowers, so where there’s a good area of long grass with wildflowers in it, they don’t need to move far.

The hot sunshine had coaxed more flowers into bloom too, particularly the blue-lilac Scabious, which is a favourite of butterflies and of many other species of insects too.

On a cooler day I would have lingered longer around this one spot and doubtless found even more than I did, but the heat out on the open hillside was intense, and if I was to find Fritillaries I had still to get up to the summit and down the other side of the hill. When I first began exploring this hillside, back in 2012, the management of it was quite different; the long grass would have been kept shorter and Ragwort considered a noxious weed and kept at bay. Gradually attitudes have changed and over the years the plant has spread considerably and a result, as well as providing important nectar and pollen for invertebrates, the numbers of plants supporting the unmistakeable black and yellow striped caterpillars of Cinnabar moths has also increased; some plants had several, others one or two.

6-Spot Burnet moths mating above a newly-vacated cocoon

Going down the other side of the hill it was Burnet moths that dominated the airways, flying low in, over and about the grassy slope. Many would have been newly emerged from their alien-pod like yellow which are frequently seen attached to grass and other plant stems. Often there is a mass emergence, with males emerging first. They then sit above the cocoon of a female and wait for her to emerge, pouncing on her to mate before she’s barely had time to draw her first breath of fresh air.

Amongst the grass on this side of the hill you can find some of this site’s loveliest wildflowers, Common Spotted Orchids; most are at the end of their flowering now, but while following one of only two Dark Green Fritillaries I saw today I found a few fairly fresh ones. There was some Dropwort too, the dry limestone grassland relative of the similar-looking moisture-loving Meadowsweet.

On the other side of the trail, where the hillside is left much to its own devices a lovely pink-purple haze of Rosebay Willowherb stands out against a backdrop of trees.

Despite my best efforts, I didn’t get my photo of a Dark Green Fritillary, but it was too hot to chase about, so I sat on the grass for a short while and enjoyed watching those I saw; they are impressive – and very fast on the wing! Luckily I have a stack of photographs taken on other occasions in this exact spot, so here’s one I made earlier.

As so often happens, there were compensations; close to where I’d stopped a Brown Argus landed on Ragwort and another fresh Gatekeeper on nearby Hemp Agrimony.

Then as I was about to turn and head back home, my favourite of all the summer butterflies, a perfectly beautiful little Small Copper landed first on a stone at the edge of the trail then flew up to a nearby Ragwort; my first sighting of one this year and a perfect note to finish on.

It had been a good while since I’d spent the best part of a day meandering around the whole rich patchwork of varying habitats that make up my local nature reserve of Bryn Euryn, so a sunny morning that was forecast to stay that way into the afternoon offered the perfect opportunity to spend a day outdoors.

09:59 – Woodland Path

Once outside I realised it wasn’t quite as warm as I’d thought it was going to be, but the air felt fresh, if slightly humid. The copious rainfalls of previous days have done wonders; plants that had looked sad and wilted a few days ago were perked upright and the leaves of the trees washed of dust and good as new. A Speckled Wood butterfly on ivy and the chirpy calls of foraging Blue Tits greeted me at the beginning of the path, which has also benefitted from the dust-settling cleansing rain.

The specialist woodland wildflowers of the early Spring have long-since finished flowering now and are directing their energies into producing seeds. There are a few later-flowering plants that can cope with the reduced sunlight though, including the beautiful Honeysuckle, one of my lifetime favourite plants whose fresh perfume I would happily fill my home with, if only someone could capture it perfectly.

An arch of Honeysuckle

It’s been a good year for this fragrant twining-climbing plant which has given me cause to make even more frequent stops on my walks; the scent of it in the air, particularly in the cooler mornings and evenings is as much a highlight as anything I might see or hear. It has maybe passed its peak of flowering now, but there’ll be occasional blooms to enjoy for a while to come.

Also happy in partial shade and flowering now are Navelwort, which is usually more easily recognised by its distinctive round fleshy leaves and Wood Sage, which despite its name is not confined to woodland paths; it’s a tough plant that is equally as happy growing out on exposed heaths and coastal cliffs.

Wood Sage-Teucrium scorodonia

Navelwort-Umbilicus rupestris

10:12 Covered with white blossoms and well-refreshed the bramble patch at the top of the first rise of the path, was my first stop this morning. Gradually being lit and warmed by sunshine, it was already busy with a variety of insects.

Honeybee on bramble blossom

A Blackbird was singing from a tree somewhere close by, his melodic, relaxed song lending an element of calm to the scene of frenetic insect activity. There were bumblebees: Tree Bumbles definitely the most numerous, some looking fresh, their heads and thoraxes bright deep tawny brown others faded to a pale blonde, perhaps bleached out by the sun. A few smaller Buff-tailed workers are busy between them and there are a small number of Honeybees, some of the first I’ve seen this year.

Faded Tree Bumblebee

Fresh Tree Bumblebee

Butterflies joined the party, two Speckled Woods, which must have been a male and a female as they behaved amicably together, feeding almost side by side until disappearing together to the privacy of the leaves of an overhanging Sycamore. A Large White scooted over but didn’t stop, but a Red Admiral, missing a piece from a hind wing stayed for the whole length of time I was there, only moving short distances between flowers.

Red Admiral

Most interesting of all were the big yellow-and-black beetles, that for some reason don’t seem to have a standardised common name, so are known to me as Strangalia maculata, (which is apparently no longer correct as they’ve changed it to Rutpela maculata!). In the midst of the tangle of bramble, honeysuckle and ivy stands the remains of a tree, which was snapped in a storm a few winters ago. I wonder if it’s within its damaged fabric that they spent their larval stage and from which they have emerged. For a while now I’ve seen them here each time I’ve passed by, several at a time. Until now all of my past and more recent sightings of these lovely beetles have been of them calmly feeding on flowers, so it was interesting to see them very active this morning, flying rather clumsily from flower to flower, not lingering for long on any.

The distant mewling of a Buzzard calling from above diverted my attention and I caught glimpses of it as it circled high above the trees.

This was the first one I’d seen in a while, so I wondered if it might appear back over the field, perhaps with its family, so moved on in that direction. It was a sun-in-and-out morning, surprisingly cool on the shady path when the breeze picked up.

Path edged with False Brome

Paths are edged with grasses, which are flowering now. False Brome predominates, covering large swathes of the woodland floor in places throughout this site, and there are lesser amounts of other species such as the distinctive Cock’s-foot.

Cock’s-foot-Dactylis glomerata

False Brome-Brachypodium sylvaticum

10:40 There was nothing to see at this edge of the woodland except the wind rippling over the long grass of the meadow, and it was too cool to linger.

The sun came out again as I walked between the pine trees. This has become one of my favourite parts of the woods. I love the characterful Scots Pine trees with their tall, straight trunks crowned on high with heavy, strangely twisted branches in all seasons; but today with their rust-red bark still slightly damp and darkened by rain and highlighted by filtered sunlight they had a special glow.

There were no birds to be seen and for a while no sound of them either, until their silence was briefly broken once again by the Buzzard and the familiar contact calls of more Blue Tits working their way through the trees.

PATH EDGES

Nipplewort-lapsana-communis

Opportunistic wildflowers crop up randomly along the path edges, mostly of those species that seem to travel alongside the blackberry brambles, accompanying them wherever they go. In flower now are nettles, dock and delicate-looking Nipplewort.

All have value to insects in their way, either as sources of pollen and nectar or via their leaves which are either eaten from the outside or mined and eaten from the inside.

Curled Dock

Common Nettle

10:47 – My next stop is at the brambly-scrubby patch at the junction of three woodland paths. In recent weeks this has been buzzing with a variety of bees, in particular Tree Bumblebees that clearly have a nest nearby, or there may even be two. There have been a lot of Early Bumblebees too, but lesser numbers of other common species and so far I’ve only seen one or two Red-tailed bumblebee queens; no workers.

Predominately a raspberry bramble patch, which flowers earlier than blackberry, there is less blossom here now so is less of a draw for foraging insects now. There were a few Tree bumblebees about though, some working, one or two taking short rests on nearby sun-warmed leaves; poor things have probably already been out working for hours. This has been a great spot for hoverflies this Spring too, where I’ve added a few ‘new’ species to my list. It was starting to get warmer, which doesn’t seem to bother bees, but hoverflies often seek shade under leaves, so I wasn’t too surprised there were few to see. Then I spotted one of the largest of our UK hoverflies, a Great Pied Hoverfly (Volucella pellucens) on some more shaded brambles. Not a new species for me, but I’d not seen one in this spot before. In contrast there were also a few of one of our smallest and commonest hoverflies about, little Marmalade Flies (Episyrphus balteatus).

Gt Pied Hoverfly-Volucella pellucens

Marmalade Fly-Episyrphus bateatus

10:46 A bird landed in an Oak tree a few metres behind the Sycamore tree, on first impressions quite big,heavy-ish landing so probably a Wood Pigeon. I almost didn’t take any more notice, but then it came to mind that this is a good spot to see Jays, which I am always keen to try to photograph as they are quite elusive, so I focussed on it and was excited to see it was neither Wood Pigeon nor Jay, but a dark handsome Buzzard. What a beautiful bird, and posing so nicely too.

The Woodland Trail

11:10 As I walked on, I remember thinking that the sighting of the Buzzard and managing to get a half-decent photograph of it was going to be the main highlight of my day. But then you just can’t predict what you may or may not see on any given day in this treasure trove of nature, as I later discovered.

Reaching the Woodland Trail, I crossed it to sit on the bench for a few minutes to enjoy the sunshine and to listen to what was around me whilst I wrote some notes. I’m always fully aware of the soundtrack of my walks, but unless I get lucky and can photograph or record a singing bird can’t always properly recall what I heard. This is what I wrote here ” … for 30 seconds, maybe a little longer there are no extraneous sounds; no noise from the road, no dogs barking, no human voices, only the sounds of twittering birds – most likely Blue Tits reassure me I haven’t gone suddenly deaf! A Robin’s just flown into the tree above me. It sits and looks at me for a few seconds before flying into the woods I’ve just left. I see a Small Heath butterfly; it lands but I didn’t spot it in time and it flew off, surprisingly rapidly for such a tiny butterfly, ditto a Meadow Brown!”

As I got up to carry on I caught sight of a small gingery-furry bee flying over a fallen tree branch, which I thought might have been a Tawny Mining bee. I tried to focus in on it, but it was flying and although I pressed the shutter a couple of times I knew the bee wouldn’t be in focus, but may do as record shots. I can’t even begin to describe my feelings when I looked at those photographs on my computer later that evening. Expecting to see an out of focus bee, there too was also an almost perfectly in-focus lizard lying motionless and perfectly camouflaged along the length of the fallen branch which the bee was flying over. It had probably been watching me and wondering whether it should stay still or risk making a move. I’m grateful it chose the latter option.

Part of me was glad I hadn’t noticed the lizard, which is a Common or Viviperous Lizard, as I’m sure I’d have been so excited to see one in a position where I might get a photograph that I’d have fumbled with the camera and likely have missed it. But then I think it would have been nice to get a proper look at one rather than just a glimpse of a disappearing one, which is all I’ve managed so far in my years of tramping this hill! Mainly I’m just more than happy to know it was there and I have a photograph, however I managed it!

Being oblivious at this point to my lizard ‘capture’, and back in insect-seeking mode, I wandered along to the huge bramble tangle that once in flower has always been a brilliant place to spot a good variety of insects in a relatively short space of time with minimal effort. Years ago, this was the first place on the reserve that I recognised as an insect ‘hotspot’. There was a fair amount of activity here this morning, mostly from bumblebees, but there was also another Gt Pied Hoverfly, a Red Admiral butterfly, a Strangalia maculata beetle that only showed me its antennae and legs and a few different species of flies. Getting photographs was tricky, insects were constantly moving, the sun was shiningly brightly, but probably more to the point the path was getting busy with people and dogs and I got fed up having to keep moving to let them pass at a ‘safe distance’.

Tutsan growing alongside the bramble already has ripening berries. Its flowers hadn’t the same degree of appeal to insects as bramble, but I did catch a little Marmalade Fly visiting it.

The woodland is at the peak of perfection now, leaves are fully grown, in a myriad of shapes and uncountable shades of fresh green; climbers and ramblers are not yet over-reaching themselves to become sprawling and untidy and the plants along the path edges are not yet spilling over it.

Speckled Wood butterflies were stationed every few metres along the path, whether basking on the ground or perched on leaves overhanging the path. Constantly on alert, they readily explode into action to see off any intruders into their territory.

Trees arch across the path creating shady leafy tunnels

First wild raspberry

Generally birds are much quieter these days, apart from the Blackbird I heard earlier the only ones still singing to any extent are our summer breeders-Chiffchaff and Blackcap.

The closed canopy makes it too shady for there to be much in the way of ground-level plants for a while, so there are few distractions, other than Speckled Wood butterflies of course and the occasional sight of a Blackbird foraging in the safety of the dappled shade.

No matter how often I walk along this Trail, several times a week sometimes, each time I see it with fresh eyes. Looking up there are places where trees on opposite sides seem to avoid contact, leaving fascinating space between their contrasting leaves.

The same scenery changes according to the lighting effects; the varying cloud cover and the angle of the sun at different times of the day as the seasons progress all contribute, as do the weather conditions, particularly on days when there’s wind and how strong it is. On the ground, complex shadow patterns may be cast on the uneven canvas of the bare-earth path.

12:05: The steps up from the shady sheltered Woodland Trail lead into what could be an entirely different dimension….

a good place to take a break..

April 19th – Bryn Euryn

Today was the middle day of the three consecutively warm sunny days that tantalised us with the notion that Spring had truly arrived, and judging by the activity here today it had a lot of our wildlife fooled too. The sky was clear and that almost-unbelievable shade of deep blue, the birds were singing and best of all, it was warm!

WOODLAND PATH

A few metres along the Woodland Path of my patch is an untidy-looking stretch, divided by the narrow path, where missing trees have opened up the canopy, letting in the light and warmth of the sun. Somewhat mysteriously, it holds great allure for diverse species of insects, some of which at certain times can be found here in surprising numbers. At the right time on the right day, ten minutes spent in this ‘hotspot’ can be as productive as two hours spent ranging over the rest of the site.

11:44 Today I was here at the right time to see a surprising amount of insects. Most prolific were hoverflies in all shapes and sizes from big and bulky to teeny-tiny and dainty.

Eristalis sp hoverfly

Syrphus sp.

There were few flowers here for nectaring upon, so that wasn’t the attraction for the majority of the hoverflies; I caught just one on the tiny flowers of Dog’s mercury. There were dozens of this small black and yellow striped species here, all very fresh and shiny and mostly basking on the sun-warmed leaves of brambles and nettles.

One side of the ‘hotspot’ is open to sunlight, clear of trees but sheltered by those standing behind it and by large shrubs of laurel and holly on either side. A large tangle of bramble fills the gap in the vegetation and is the only barrier between you and the Expressway below at the bottom of an almost-vertical slope. (Only joking, there’d be plenty of trees to stop you if you fell!) On the other side is a large patch of nettles, the aforementioned Dog’s mercury, more bramble and a pretty patch of periwinkle, all growing through a ground-covering of ivy.

Periwinkle

Dog’s Mercury

A lone Tree bumblebee flew in, visited a couple of the periwinkle flowers then stopped to bask on a last-year’s half-eaten bramble leaf. I think it was a male (no pollen baskets) and was looking a bit the worse for wear. He seemed to have a burden of mites and I wondered if exposing them to warm sun might dislodge them. I’ve seen birds do that.

A smaller bee caught my eye as it came to rest on an ivy leaf. I didn’t realise what it was until I saw my photograph, then was excited to see it was a Hairy-footed Flower Bee, this one a male and my first record of this species here.

Hairy-footed Flower Bee – Anthophora plumipes (male)

Hairy-footed Flower Bee (m)-Anthophora plumipes

A species common and widespread in much of England and Wales, especially in towns, cities and villages. Often nests in the soft mortar and exposed cob of old walls, but occasionally will nest in the ground, preferring bare compacted clay soils. Flies from late February to mid-June, and is particularly partial to Lungwort (Pulmonaria) flowers.

Males and females look very different from one another: the female resembles a small, black bumblebee with orange-red hairs on the hind leg and a rapid-darting flight; she’ll often approach a flower with her long tongue extended. Males are mostly brown with a dark tail (fresh specimens are gingery). Cream markings on face distinguish it from all bumblebees.They are often among the first bees of the year to emerge and often hover in front of flowers and when pursuing females.

Another little bee came to rest on a nettle leaf, this one I recognised as an Ashy mining bee and another male.

Ashy mining bee – Andrena cineraria (male)

Ashy mining bee (m)-Andrena cineraria

A distinctive and obvious spring-flying solitary bee. Females are black, and have two broad ashy-grey hairbands across the thorax. Males emerge well before the females. They look similar, but their thorax is entirely covered with less dense grey hairs, and there’s a pronounced tuft of white hairs on the lower face. Species has a single flight period each year from early April until early June. Nests are constructed in the ground; entrances are surrounded by a volcano-like mound of excavated spoil; often in dense aggregations in lawns, flower beds, mown banks and in field margins.

And where there are mining bees there are those who would prey upon them….. Bee-flies: quirkily-cute in appearance but not good to know if you’re a hard-working mining bee; they’ll spy out your nest-hole and craftily kick their eggs inside with those long legs, then later their hatched larvae will feast on yours.

Bee-fly-Bombilius major

Wasps were out on the prowl too; I didn’t get a clear enough image to tell if this was a German or Common Wasp – the latter have a distinctive anchor mark on their face; this image is a bit fuzzy.

12:07 I could have lingered longer, but birds were singing, I’d been serenaded by a Song thrush and a Robin as I stood watching insects, Blue tits twittered on all sides and I was keen to see what else was happening.

Bluebells are beginning to flower and offer nectar to those that can reach it, there’s also Greater Stitchwort and lots of Dog Violets. A male Orange-tip butterfly raced past me over the bluebells and through the trees, clearly on the trail of a female and not stopping for an instant.

Greater Stitchwort – Stellaria holostea

There are masses of glorious glossy golden yellow lesser celandines shining in the sunlight too.

I stopped to admire the celandines lining a section of the path and not at all concerned by my presence, a Blue tit perched above me and began to sing.

Beneath him dozens of shiny new flies arrived to bask on soft sun-warmed new bramble leaves.

There’s one special spot I know where Wood Anemones light up the woodland floor like fallen stars, turning their faces to the sun

and another where those of the shamrock-leaved Wood sorrel shyly hide theirs.

Over the boundary fence, the formidable thorny boundary hedge of gorse and blackthorn is softened now with their fragrant gold and white blossoms.

I heard a bird singing, a short loud burst of notes that I thought at first was a Wren, but it wasn’t quite right. I’d forgotten that another tiny bird, the Goldcrest also has a disproportionately loud song, remembering when he broke cover and flitted about in shrubbery in front of me. He wasn’t going to oblige me with a photograph, much too busy! So I stood gazing upwards for a while – you can’t get too much beautiful blue sky…

… or pretty blossom, can you?

WOODLAND TRAIL

12:58 There’s another hotspot around the junction of my Woodland Path with the reserve’s Woodland Trail, this one for birds. Here there is a territory of both Blackcap and Chiffchaff so there is the possibility of hearing if not seeing both species here. Today I was lucky; I heard the Blackcap’s song as I approached and walking slowly and as quietly as I was able I spotted him. He continued to sing but moved restlessly through the branches as I got nearer then flew off across the other side of the track.

While he sang from behind foliage over there I watched a pretty female Tawny mining bee feast on Blackthorn blossom.

Then the Blackcap came back to where he’d started, so I think perhaps his red-headed mate may be on their nest somewhere close by.

This gorgeous gorse is below his singing tree. It would make a safe place to nest and the flowers would attract insects for dinner.

I had heard a Chiffchaff singing nearby too but was pleasantly surprised when he appeared, continuing his song while flitting about amongst the twiggy branches searching for insects.

13:21 Further along the trail I spotted a flutter of orange – a lovely fresh Comma butterfly basking on dry leaves at the edge of the path. As I watched it moved, (look away now if you’re squeamish) onto a thankfully dryish dog poo deposit. I had to take the picture as it nicely presented its underside showing off the distinctive white mark for which it is named.

The disturbed ground of the pathsides supports some of the ‘weedier’ wildflowers like dandelions which provide important nectar when there’s not much else in flower.

You’d be very unlucky not to hear and see a Robin singing along here, there seems to be one at regularly spaced intervals. They sit and watch out over the track then dart out to pounce on any potential prey they may spot. This one had been singing but stopped to watch me.

I waited to see if he’d start singing again and was distracted by a bird whistling loudly. I scanned around searching for whatever was making the sound, one I didn’t recognise at all but that sounded to be being made by quite a large bird. After a few minutes the whistler appeared and to my amusement turned out to be …. a Great Tit! Of course it was, one of the basics of birdsong recognition is ‘when you don’t recognise it or haven’t heard it before, chances are it’ll be a Great Tit’; they have an incredible repertoire of sounds to call upon. I was thankful to him for keeping me in that spot though, as this gorgeous Greater Spotted Woodpecker flew onto a tree trunk literally right in front of me.

The Woodpecker stayed there, keeping a watchful eye on me. This bird is a female and is holding something small in her beak, so I imagine she has a nest nearby and was unwilling to reveal it. I moved away quickly, thanking her for the photo opportunity as I did.

Great Spotted Woodpeckers are about the same size as Starlings. Their plumage denotes their age and sex. Juvenile birds have red foreheads that are replaced by black as they moult in the autumn. Adult males then have a red nape while females have no red on their head at all.

The Lesser Celandines have been late flowering this Spring but are glorious now and more prolific than I’ve seen them before. It’s not just the flowers that are prolific, so too were hoverflies and Bee-flies seemed to be everywhere.

Approaching the entrance to the meadow another Robin, which looks as though it is singing, but was actually ‘ticking me off’, let me know it didn’t appreciate my disturbing it.

THE UPPER MEADOW (ADDER’S FIELD)

The grass of the meadow was cut back hard last autumn and so far there’s not much happening there yet, but the grass is beginning to grow and the cowslips are starting to come out. They’ll be later on the more exposed ‘downland’ side of the hill.

Another Bee-fly settled on an exposed rock in the pathway, fluttering its wings rapidly and making flicking movements with its legs as they do when depositing their eggs, but there was no sign of a mining bee nest anywhere near, so not sure what it was doing.

Summer Rainfall Prediction:

If oak is out before the ash, there’ll be a splash ; if ash is out before the oak there’ll be a soak…

Keep the brollies handy, looks like ash is furthest on so far….!

Wriggling across the still-damp ground on the way to the Summit Trail was an earthworm. Double jeopardy came to mind – exposure to warm sunshine and hungry birds; foolish worm.

Last year I noticed spots along the trail here where Mining Bees were making nests. having seen a few about today I kept an eye out for more signs of their activity and spotted these little ‘volcanoes’, evidence of their presence. I waited a while but no bees showed, so I don’t know which species had made them, but I think maybe Tawny Mining Bees.

THE SUMMIT

It was cooler and breezier up here. I walked carefully, hoping there may be Small Tortoiseshell butterflies basking on the bare earth of the path, but not today, although I did see two busily chasing one another at speed as they disappeared over the edge of the cliff.

The mountains and the distant Conwy valley were veiled by a misty haze.

The blackthorn is smothered with blossom and looking beautiful. It will be interesting to see how much of it gets pollinated and develops as fruit this autumn. Sloe gin comes to mind.

Blackthorn – Prunus spinosa

The path back down to the Woodland Trail felt almost bridal with falling petals showering down onto the ground like confetti. A pretty way to end this account of a lovely walk.

September 8th-Bryn Euryn

As I’ve already said, it was mighty windy out here on the not-quite-summit of the hill; not the day for hanging around gazing at the views, no matter how stunning they may be.

Windswept not-quite-summit of Bryn Euryn

A quick look around showed there to be little left in the way wildflowers in bloom, but there was colour on a wild rose – a whole colony of bright red Robin’s Pincushion galls. I don’t recall ever having seen as many on a single plant. The fuzzy growths will gradually fade to brown and the little wasps that cause the growths will emerge in June. If I’m lucky, one of these days I’ll catch them coming out, although the galls also attract ‘squatters’ and there can be a dozen or more species lodging in there!

I was to keen to keep moving, but when I spotted this lovely patch of Eyebright I couldn’t resist stopping again.

The dip between this part of the hill and the slope up to the summit is usually sheltered and offers a brief respite from the wind and the noise of traffic from the A55 below, but not so today. Yarrow likes this spot and there was quite a good large patch of it still in flower here. As with Eyebright, Yarrow is a plant designed to withstand tough growing conditions and is pretty persistent, as anyone that has tried to eliminate it from a lawn will testify; you cut it down and it grows right back! Personally I prefer the ferny-leaved Yarrow to the boring grass! Funny how we discriminate against certain plants, this wildflower Yarrow’s taller-growing golden-yellow flowered relative, Achillea, is a cherished garden plant!

Some insects rather like its flowers too, I found a tiny bee motionless on a flower today and recalled I’d seen a similar looking insect on Yarrow in the Rhiwleddyn reserve a few weeks ago.

Tiny bee on Yarrow – enlarged

On the summit a patch of purple Knapweed was fuelling a few Common Carder bees that were managing to cling on and fly short distances despite the best efforts of the wind to dislodge them. The little bees had varying appearances; some were practically perfect, others a bit more battered, their ‘fur’ worn away and at least one that had a bleached appearance like it had spent too long out in the sun.

Common carder bee-practically perfect

There was another lovely clump of Eyebright up here, this one framed by the distinctively-arranged pods that give the Bird’s-foot trefoil its name.

More Yarrow too, this plant sheltering a tiny fly.

I was hoping that the other side of the hill would be a bit more protected from the wind, but alas, most of it wasn’t. The sun was putting in sporadic appearances though, so at least it felt a bit warmer. Ironically, the sea looked to be calm, was coloured in shades of beautiful blue and its surface merely ruffled. The blades of the wind turbines were motionless.

Looking over in the opposite direction to te sea, the view to the oddly-shaped hill at Deganwy, was fairly clear, although beyond it, Anglesey and the Menai Strait were shrouded in a light haze. I’m not sure if I’ve mentioned it before, but the hill is named the Vardre and gets its unusual appearance from having two rocky summits. It has a little less height than Bryn Euryn, it being 108m, (354 feet) while the Bryn is 131m (365 feet). It was once home to fortifications that included Deganwy Castle.

On the woodland edge leaves are beginning to change colour. Hawthorn is one of the first to go

along with Silver birch as I mentioned in the previous post. Out here in the open it was easier to appreciate the combination of yellow leaves against a clear blue sky.

Next to the Silver birch is a single Whitebeam, which bears berries. The berries are orange in colour now but will gradually turn red.

In the short grass there are still a few Rock-roses in flower and here and there are big fat ‘penny-bun’, or Bolete mushrooms. At least they would have been big and fat before they were nibbled away. I like the different shades and textures such nibbling has left on this one; there was a little black spider on it too.

I have often wondered what nibbled the mushrooms. A picture I took a few weeks ago, at the end of July may have the answer. The sight amused me and I wondered if it was a romantic al-fresco lunch for two? Of course there is more to slugs than meets the eye. No gardener is ever going to welcome them onto their plot, but out in the wild they are another important cog in the wheel of the natural waste-disposal system. Although one slug may look rather like another, there are rather a lot of different species of them in our British Isles. I submitted this image to the very helpful folk that run the Slugs and Snails of the British Isles Facebook Group, who responded that to be accurate they need to see the undersides of the slugs too, but from other features that it is likely they are juvenile Arion flagellus – the Green-soled slug.

poss. Arion flagellus- the Green-soled slug

The bottom of the grassy ‘downland’ hill was still flowery with Hemp Agrimony, Knapweed, touches of Scabious and a sprinkling of Ragwort.

I walked down to where it meets with the woodland edge and lo and behold, for a few glorious minutes the sun came out. Suddenly it was warm and bright and the scene came alive with a whole host of insects vying with one another for the best blossoms.

Speckled wood on Hemp agrimony

I hardly knew where to look first, but then couldn’t resist the sight of a pristine Speckled wood feasting on Hemp agrimony. There were several of them, all looking freshly beautiful; most were nectaring on various flowers while some rested on the leaves of nearby trees basking in the sunshine. The only other butterflies in evidence were Red Admirals which unusually stayed out of range of the camera.

There was a good variety of hoverflies,large and small, a Common wasp and more Common carder bees too.

Volucella zonaria

A beautiful cast of insects, but the star of today’s show was a big handsome hoverfly, which surprisingly doesn’t have a common name, but whose scientific name, Volucella zonaria makes it sound a bit like an Italian pasta dish. This is the largest British hoverfly and is quite a recent addition to our native list, appearing on the south coast of England during the late 1930s. According to my Hoverfly bible, from there it has spread upwards and outwards across the country as far as Cheshire and Humberside and South Wales in the West. We’re not so far from the Cheshire border here, so they must still be spreading, this is the second one I’ve seen this year, the other was in my daughter’s garden a few weeks ago.

The spell of sunshine didn’t last long and the wind was still blowing relentlessly; time to set off in the direction of home.

Part 3 – Rhiwleddyn Nature Reserve

It is wonderful to wander through places that have been left alone and to find indigenous plants that could have been growing there for hundreds of years, or in some cases, even thousands. But areas that have in one way or another been ‘disturbed’ often bring forth species of flora and fauna not seen in areas that haven’t, as in the next part of my wander around the reserve.

Brambles and nettles threaten to take over this small, scrubby area in the midst of the reserve, but there are plants tough enough to hold their own there, one being Common Sorrel.

Common Sorrel Rumex acetosa

The tall stately Great Mullein with its large beautiful grey-green velvety leaves sometimes graces a disturbed scrubby patch. It’s a biennial plant, so flowers appear during each plant’s second year. It is a locally common plant, but its appearance in a specific area each year is not predictable; which makes it more of a treat when you do find it. Each plant usually produces a single flowering spike; one with multiple spikes may indicate that it was nibbled by rabbits in the early stages of its growth.

Great Mullein – Verbascum thrapsis

White horehound, is one of the scarcer plants to be found within the reserve. Its presence here is tenuous year on year, as it is constantly under threat of being out-competed by rampant ‘coarse’ vegetation such as nettles and brambles; its survival largely dependent upon diligent scrub-clearing and management by the reserve management team and Wildlife Trust volunteers. The plant is also found, in greater amounts, on the Great Orme.

June 2017-larva of the Horehound Moth – Wheeleria spilodactylus on foodplant

White horehound is important as it is the only food plant of the larvae of the Horehound Moth Wheeleria spilodactylus. Inhabiting chalky soils, this is a localised species of plume moth, largely confined to the Isle of Wight and a few scattered localities in Wales and Southern England. The exceptionally well-camouflaged caterpillars appeared on plants here earlier in the year when I took this photograph; they are evidence that the battle to maintain its ongoing presence is important to this species of moth.

I haven’t seen the moth myself, but found this perfect picture of one, appropriately taken on the foodplant on the Great Orme by John Martin. Respecting the copyright of the image, this is the link to it. http://www.ukmoths.org.uk/species/wheeleria-spilodactylus/adult-on-foodplant-2/

A little grasshopper sat basking, sheltered from the wind and very well camouflaged on a bramble leaf. I doubt I’d have seen him if I’d not caught sight of him land there.

Grasshopper on bramble leaf

This is him/her greatly enlarged

Another tough plant here is the Lesser Burdock. I like the plant with its round prickly flower heads and tufts of purple flowers that will soon dry into ‘burrs’ and stick to anything that brushes against them. I approached the plant to photograph it; as I did so, I got excited to see that a little butterfly had the same idea and had only my second sighting so far this year of a perfect little Brown Argus.

Brown Argus Aricia argestis

The poor thing was fighting to stay put in the strong wind and I was struggling to keep my camera lens focussed on it. I was vaguely aware of a small fly sharing the same space on the plant as the butterfly, but was too intent on the matter in hand to pay much heed to it. It was small and yellowish and flitting about a fair bit, but at the time it didn’t click that this might be a fly I’d been hoping to find for the past few years that is a burdock specialist.

Brown Argus & Banded burdock fly

Banded burdock fly-Terellia tussilaginis

It wasn’t until the next day, when I looked at my images properly that I realised this little fly was indeed most likely a Banded burdock fly-Terellia tussilaginis and that I’d almost missed it!

At least it gives me good reason to show more images of the lovely little butterfly.

Brown Argus & Banded burdock fly

I was getting a bit fed up with the wind now but battled on towards the top as I wanted to get an image of the stunning view of Llandudno that you get from this side of the Little Orme headland. It was only when I got there I remembered that I had actually been somewhat sheltered from the full force of the wind! it was still so strong it took my breath away and I had to lean against a rock to brace myself, not only to steady the camera but also myself. Worth it though, what a view!

I didn’t stay to lingeringly admire the view, and was quickly on the way back down to seek a calmer spot. Facing now in the other direction and looking down onto the fields below I had the random sight of a male Pheasant, not a bird I see often. He was looking a bit bedraggled and was clearly limping. Had he been been shot and survived, hit by a car, or even attacked by a fox or dog? Fortunately he seemed still to be able to fly well enough.

Limping pheasant

A little further on I spotted a little splash of blue in the short grass in front of me and much to my surprise here was one of the Reserve’s special treasures – a single stem of the lovely little Spiked Speedwell. This is a plant that is cultivated and grown in gardens, but only grows in the wild in the Breckland grasslands of East Anglia and very locally in Wales and Western England.

Spiked Speedwell-Veronica spicata

A few metres away, standing a little taller, a single flower stem of Dropwort, another specialist of calcareous grassland, this one being bent almost to the ground by the strength of the wind.

Dropwort – Filipendula vulgaris

Hawthorn is one of the few species of tree that is not nibbled by rabbits or sheep in its early stages and that can also withstand exposure to the strong, salt-laden winds the headland is subject to. Most are contorted into weird and wonderful shapes, but this one, although short has grown large and spread fairly evenly.

I met up with the young Robin again on my way back down.

Young Robin

And a beautiful Comma butterfly landed on the bare earth of the track.

Comma

The sheep were where I’d left them, settled down comfortably now for an afternoon siesta in the sunshine.

Looking up from the track below I saw they were still watching me, with definite smug, self-satisfied smiles on their faces.

I was more than happy with my final wildflower tally for this walk, which included (in no particular order!): Common calamint; Common rock-rose; Black horehound; White horehound; Hedge woundwort; Water mint; Lady’s bedstraw; Spiked speedwell; Dropwort; Wild thyme; Common cinquefoil; Centaury; Carline thistle; Goldenrod; Lesser burdock; Common sorrel; Great mullein; Harebell; Perforate St John’s Wort; Wild clematis; Yellow-wort; Wild fennel; Marjoram; Wild carrot; Hemlock; Ragwort; Ploughman’s spikenard; Yarrow

Part 2 – Rhiwledyn Nature Reserve -The main track

Onwards and upwards; a flight of shallow stone steps make a steep rocky section of the path a little easier to climb (except when it’s wet & they get a bit slippery).

Pause here to admire the views back down onto the road and the many shades of green of the fields and woodland on its opposite side.

Looking down onto the road into Llandudno

Facing around to the way I’m going, the views to the right of me, seen over a rampant tangle of brambles and wild clematis on the reserve boundary, are extensive and stunning. At once pastoral and contained and wild and open to the elements.

On the other side of the track is the biggest and best patch of harebells that I have seen for years, a truly beautiful sight.

Harebell- Campanula rotundifolia

I can’t resist sitting to watch them being blown and rippled by the wind and am captivated by their charm. For me this little flower has it all. Beautiful in colour and form, they have delicacy and fragility but also great adaptability and resilience to an often hostile environment. Each flower had turned its bell back to the wind to reduce its impact; their slender but tough and wiry stems having the flexibility to bend to the wind, not break. A life lesson in a wildflower!

There were yet more of the little beauties a little higher up on the slope contrasting delightfully in colour and form with frothy lemon-yellow Lady’s bedstraw. I clambered up rather inelegantly to take a closer look. Amongst other plants, these had grown taller and in a more sheltered spot, their bells were turned to the light rather than away from the wind.

Before going back down to the track, I take another look at the glorious view across the bays to the Clwydian Hills and with sheep where they are supposed be.

click to enlarge

Back on track there is a change in ambience and habitat. There are small trees and shrubs on the boundary with the farmland sufficient to cast shade, and the sloping ground on the other side provides a windbreak. The trees are mostly hawthorn, prevalent throughout the headland as its one of the few plants not grazed by sheep or rabbits and again, tough enough to withstand exposure to fierce salty winds.

I spot a movement and see a small Grasshopper jump onto a lichen speckled rock catching dappled sunlight; the perfect place to soak up a little warmth whilst staying camouflaged.

I round a bend in the track and see – sheep! Five naughty trespassing sheep! They are strictly banned from the reserve unless invited in as their indiscriminate grazing may damage or even destroy the rarer wildflowers that grow here. Fencing prevents them wandering into the higher part of the reserve from the rest of the Little Orme where they are not restricted, so I think they got in at this field level, no doubt irresistibly tempted by the sight of the lush long grass over here. I tell them they should return to their field, but can’t see where they may have got through and they pay me no heed anyway, just amble away showing me their bottoms.

I let them get ahead, the last thing I want to do is frighten them and send them scattering and concentrate on the patch of golden flowers I see amongst the long grass on the slope. I thought at first it may be Goldenrod as I’d seen some on the roadside earlier, but soon realised it was a Hypericum – St.John’s Wort.

Another plant with several species that share the same common name, but this is the one I am most familiar with and has all the right features to be Perforate St John’s Wort – Hypericum perforatum.

St John’s Wort-Hypericum perforatum

Black horehound – Ballota nigra

I apologise, but need to digress a little here to explain the significance of my next plant. Earlier on in the summer a group of NWWT members were treated to a walk around this reserve guided by its manager, Rob and a guest expert botanist, Nigel. It was a brilliant walk on many levels and we learnt a lot about our special flora and its history, about its fauna and the trials and tribulations of modern Reserve management. Typically as on any walk, even guided group ones, I lagged behind snapping interesting stuff and in a rough bramble-and- nettle patch (in the pic above), spotted the plant to the right, which is still going strong. Yet another minty-looking one I didn’t recognise. I took hasty photographs and hurried after the rest of the group. No-one else immediately recognised it either, so Nigel suggested I email the pics to him later on so he could have a better look. From them his best guess was that it was Black Horehound, reservations having been that this was a vigorous, tall specimen of a plant that usually is, in his words, ‘much scruffier-looking’ He also mentioned it smells unpleasant, so this time I had a closer look and bruised and smelt a leaf. It definitely did not smell pleasant and as all its other important bits match the botanical specs, I’m taking that as another one to add to my list of wildflowers-I-will-know-how-to-identify in the future. (Unless anyone has a different idea……?)

It’s amazing what you can see in five minutes along a short shady stretch of track. I watched a dragonfly patrol up and down at speed, pausing only in his labour several times to ‘buzz’ me and let me know I was in his space. I was hoping he’d stop so I could at least see what he was, but no, much too busy. There was yet more mint here, and one I recognised from the distinctive scent of a crushed leaf – this is Water Mint-Mentha aquatic. A similar-looking plant is Corn Mint, but it grows shorter than this and doesn’t have a ‘terminal’ flowerhead (one that crowns the top of the stalk).

Water mint-Mentha aquatica

A fresh-looking Speckled Wood rested on a sun-warmed stone on the path

Speckled Wood

and a Red Admiral flew across to seek out the nectar of bramble flowers

Red Admiral – Vanessa atalanta

There is a farm gate here which I checked for security, but tightly closed there would have been no exit for sheep. Another great Clematis-framed view from here, considerably enhanced by the clouds I think, although they were blocking out the sun at this point.

click to enlarge

At the side of the gate another member of the Lamiceae (mints & dead-nettles) family, this one I know well, the Hedge Woundwort Stachys arvensis.

Yellow Dung Fly – Scathophaga stercoraria

I moved on and round the next bend found evidence I was still on the trail of the errant sheep; a smallish neat and fairly recent deposit of fresh dung. And where there is dung there may be Dung-flies, one of my favourite insects, although I’m not exactly sure why. Perhaps because I’m keen on recycling? As I hoped, a single male Yellow Dung Fly had laid claim to the heap of treasure and was intent on guarding it. A bit of a drama then ensued, but I’m saving that for later.

To the top

I had reached the Reserve boundary, marked by a gate through which the two marked ‘Trails’ continue on to cross the rest of the Little Orme headland. There is no marked official track up to the top reaches of the reserve from here though, so getting up there is a matter of a)wanting to; b) paying attention to where you are putting your feet; c)taking care not to slip on damp grass and d) watching out for rabbit holes.

Rock-roses are still fresh and lovely up here, as is the fragrant Lady’s Bedstraw.

I followed the path chosen by the sheep; they almost always know how to find the best way upwards. They were up there now, all standing facing the view. I may have thought they were admiring it, but one of them who seemed to be in charge, maybe the mother of some of them, was bleating loudly, eliciting a response from the field below. Was she calling to her friends telling them about the feast to be had on this side and inviting them over?

Once more I reminded them they were not welcome here, but Mrs Boss Sheep just gave me ‘the look’ that clearly said “mind your own business and what are you doing up here yourself?” Once past them it became more overgrown and not as clear where to head, but I kept going in the general direction of where I wanted to be and hoped for the best. I heard a bird making some squeaky sounds and spotted him as he perched atop a gorse bush, a speckly young Robin beginning to get his adult feathers. I realised this was the first bird I’d seen and heard so far on this walk apart from gulls and the occasional cormorant flying overhead.

I also realised it was lunchtime, so time to find a sheltered spot, take a break and sit and admire the sheep’s-eye view.

A Windy Wildflower Trail

August 3rd – Weather – intermittently sunny, warm but with a very strong cooling wind.

As August began I wanted to get out to see wildflowers. This is one of my favourite times of year for that, when there is every chance that there may be earlier flowering plants still around and the late-summer bloomers should be at or reaching their best. Most of the sites I visit regularly are good for wildflowers, but as they are mostly located on hills or headlands and exposed to the elements, they would not be particularly enjoyable on a strongly windy day like today and taking photographs would be difficult. I decided on Rhiwledyn Nature Reserve, one of my favourites as it covers a range of interesting habitats within its 12 acre site and as it is located on the eastern side of the Little Orme there was a chance that much of it would be sheltered from the worst of the wind.

There are three ways to access the reserve, all of which require a bit of an uphill hike. One route is from Llandudno, another from the other side of the Little Orme, but for me the most interesting route to its main entrance is along the path at the base of a section of the Orme that runs up Penrhyn Hill. Marked as a 10% gradient, this is a steepish stretch to walk, but worth the effort as the rock supports an array of plants, both wildflowers and some garden escapees, and is a nature trail in itself. This provides me with the perfect excuse to amble up the hill and take frequent excusable pauses for breath rather than stride purposefully along.

Looking back along Penrhyn Hill towards Penrhyn Bay. The hill in the centre background is Bryn Euryn

Part 1 – Penrhyn Hill roadside to the reserve

My first sighting was of a male Common blue butterfly taking a break from his battle with the wind on the flower of a hop trefoil, low down in the vegetation. Amongst long grass and ivy, a grey leaved Yellow-wort; this is an annual favouring short calcareous grassland but is found in a variety of spots throughout the headland.

Common blue

Yellow wort-Blackstonia perfoliata

There were several clumps of a plant that was definitely a member of the mint family with strongly aromatic leaves. I don’t know what it is yet.

since publishing this Suzanne has kindly suggested in a comment that it is Common calamint Clinopodium ascendens. This is a mint that grows in dry grassland, hedgerows and verges, often on chalk or limestone soils, so habitat fits perfectly.

Common calamint – Clinopodium ascendens

And another aromatic plant – Wild Fennel, growing as tall as me, in front of gorse.

A pretty snail clung to the leaf of a Valerian plant; I lifted it gently to check the colour of its underside lip – brown – then replaced it. A few bees were braving the breeze, mostly Buff-tailed bumblebees. I photographed one on marjoram, which may or may not be a wild plant.

: Brown-lipped snail

: Buff-tailed bumblebee on marjoram

There is Wild Carrot in various stages of flowering from tight buds to maturing seedheads. Most often found in rough grassland, near the sea and again mostly on chalky soil. This is one of the easier of the white umbellifers to identify, with feathery leaves and bracts beneath the flowerheads and always a red flower in its centre.

: Wild Carrot-Daucus carota

Windy days are not good for butterflies, but I did see a couple of Gatekeepers. Both sticking close within the vegetation, one found Marjoram to nectar on, the other attempted to bask on a Wild Clematis leaf. Both were faded and looking a little the worse for wear.

A flowering Goldenrod plant sprawled out across the edge of the path.

Goldenrod – Solidago virgaurea

So too a sprawling patch of Montbretia

Montbretia

and this one with its flowers like small dandelions, which I think may be one of the Hawkweeds. Another one to work on.

A stone wall marking the boundary of the farm’s land breaks the vegetated path edge, but behind it the small field is golden with Ragwort and long seeding grass. There were butterflies in there, mostly Whites, but it’s off-limits so couldn’t get a closer look.

Trees on the edge of the small wood in the background of the photograph now cast shade over the path and its edge and there are less flowering plants. There is plenty of ivy, Wild Clematis a flourishing Wild Cabbage, more of the not yet id’d mint and a clump of the usually sun-seeking Rockrose.

Rhiwledyn Nature Reserve

Half an hour after parking my car I finally reach the entrance to the reserve. The sun is shining and a fly basks in the warmth reflected by the glass of the narrative board.

A pretty clump of Marjoram flowers at its base.

I turned left to first walk the short length of the path at the base of the headland where it meets Llandudno Bay. The strength of the wind here took my breath away and walking into it head on was a challenge, but now I’d got this far I wanted to carry on to the far end of this eastern side of the headland as far as I could.

Up on the cliff a patch of harebells gave a rare opportunity to get close to these lovely little flowers without having to lie on the ground. They look delicate and their thin stems seem fragile, but they are tougher than they look and were holding their own in today’s wind.

Spiky starry Carline thistles caught my eye. Kneeling to photograph them I see they are growing amongst bird’s-foot trefoil and that there is another little star there too – a tiny white flower of Pearlwort.

There is Yellow-wort flowering next to Wood sage which is setting seed.

Another Carline thistle, this time with Eyebright and an unwelcome invader, cotoneaster, one of the banes of the lives of hard-pressed reserve managers.

Nearby, more Harebells with a little pink Centaury and the grey felty leaves of Mouse-eared Hawkweed.

I was almost relieved to reach the end of the track and be blown back to retrace my steps to the beginning of the upward track.

First I went ‘off piste’ a little to reach a stand of golden yellow Ploughman’s Spikenard.

Ploughman’s Spikenard – Inula conyzae

Then a scramble back down to the start of the track proper. A badged wooden post here reassures you that you are officially following both the Wales Coast Path and the North Wales Path.

Of Cabbages and Butterflies

In these days of declining numbers of many, if not most of our butterfly species, I wonder if we will ever be persuaded to look more fondly, or at least a little more appreciatively upon our more common White ones? Might it have helped if those early entymologists and pioneer collectors had bestowed them with pretty common names, rather than the functional ones of Large or Small Whites?

The truth is, probably not. The butterflies downfall from our grace, supposing they were once in that state, coincided with our cultivation of cabbages and other related members of the brassiceae family for our own consumption. Plants that contain the stuff essential to the health and well-being of these butterflies’ larvae, as decreed by their evolution. The plants became abundant and readily accessible to the opportunistic butterflies and why would they not take advantage? They dared to invade our space though and became a serious pest, even an enemy. This is why many of us have grown up still calling both Large and Small Whites ‘Cabbage Whites’, especially if our parents grew our family’s veg. And why school cabbage often had a boiled green caterpillar in it.

In 1717 James Petiver published the first book devoted exclusively to British butterflies, entitled Papilionum Brittaniae Icones. In it Petiver gave English names to a number of species, some that he made up himself. Others were taken from existing common useage, including Pieris rapis (brassicae), which he called the ‘Great White Cabbage Butterfly’ and/or the ‘Great Female Cabbage Butterfly’.

2016 has not been the best year for butterflies in general and my collection of species photographed so far had several gaps in it compared to last year’s, two of which were reserved for the Large and Small White. A walk on the Little Orme today filled one of those gaps. I was walking around the base of the cliffs, mostly looking up as I had spotted a Raven perched on a ledge and was trying to get close without disturbing it. It flew off of course, but below where it had been was a large bramble bush smothered in late blossom. Only as I got close to it did I realise it was attracting a crowd of White butterflies; so well camouflaged against the pale flowers in bright sunlight that I hadn’t noticed them.

Most of the butterflies were females, newly emerged, in need of food and clearly available to male interest. It took a few minutes for me to realise why there were so many here and where they had come from: until I spotted one fluttering around the leaf of a Wild Cabbage plant in fact! I couldn’t believe it had taken me till now to make such an obvious connection; the amount of times I have seen White butterflies here before, have noticed (and blogged about) the abundance of Wild Cabbage plants …… Oh well, I got there in the end!

The Wild Cabbage (Brassica oleracea), sometimes known as Sea Cabbage, is regarded as scarce by botanists as it is found in only 100 x 10km squares in the UK. The Little Orme and Great Orme in North Wales and the Gower Peninsular in South Wales are strongholds of the plant. Where it does occur, the plant is found on maritime cliffs, usually of limestone or chalk, typically growing on or near to cliff tops or cliff bases, often on ledges containing other mixed herb communities.

The Large White Pieris brassicae is a strong-flying butterfly. It is indeed large; males have a wingspan of up to 63mm & females of up to 70mm. Both have bright white wings with black tips to the forewings that extend down the wing edges. Females have two large black spots and a dash on both sides of each forewing that are absent from the upper surface of the males. The undersides are creamy-yellow.

In the British Isles the Large White is double brooded and females lay eggs any time from March to October. Most are laid during July and August when the numbers of resident butterflies may be increased significantly by migrants arriving from Europe. This also happens to coincide with maturing brassica crops.

Plants and insects have evolved together: plants needed butterflies for pollination and in return plants provided foliage for their caterpillars. The plants chosen as egg-laying sites by the Large White typically contain mustard oil glucosides, whose primary function when subsequently eaten by the larvae, is to make them distasteful to predators such as birds and protect them from attack. The preferred larval food plants are primarily various Crucifers, but they will also use Wild Mignonette and in parks and gardens Nasturtiums may be targeted.

August 26th

Back on the Little Orme to see if I could find Large White eggs and/or caterpillars on any of the plants around the bramble bush.

The butterflies avoid putting too many eggs on one plant to prevent the caterpillars running out of food and it took me a while to find an intact leaf that had an egg cluster beneath it. I only managed to find one caterpillar in a very early stage of its development, and as Small Whites also use the plants I can’t be sure which species it belongs to.

I finally found a well-grown Large White caterpillar on 10th September on a Wild cabbage leaf on an exposed part of the cliff directly overlooking the sea. It was a sunny day but with a chilly breeze and it wasn’t moving much. Clearly confident nothing would try to eat it.

The Butterfly’s Status as a Pest species

In the present day, areas such as Great Britain, P. brassicae are now less threatening as pests because of natural and chemical control reasons. However, it is still considered a pest in other European countries, in China, India, Nepal, and Russia.

The most susceptible crops to P. brassicae damage in areas in Europe include Brussels sprouts, cabbage, cauliflower, Kohlrabi, rape, swede, and turnip. The attacks to crops tend to be localised, but can lead to 100% crop loss in a certain area. In addition, because of its strong inclination to migrate, adults may infest new areas that were previously free from attack. It is estimated to cause over 40% yield loss annually on different crop vegetables in India and Turkey.

August 3rd

Did I mention the strong west wind that was pushing the rain clouds across the mountains towards us? Only once I’d left the shelter of the trees to continue upwards did I realise how strong it was, with sustained gusts forcing the long grasses and wildflowers to bend to its will.

The grassy edges of the lower summit are full of wildflowers. On the exposed side there is mostly Knapweed, with touches of Ragwort and a white umbellifer I think is Upright Hedge Parsley. There was more Red Bartsia, just one plant as far as I could see, but a better one to see properly than the one lower down. On the other side, sheltered by a belt of Blackthorn, the red berries of Lords and Ladies, Cuckoo Pint if you prefer or plain old Wild Arum.

I didn’t take this exposed path to the summit today, but ‘turned left’ to continue into the sheltered hollow where I thought there may be more insect activity.

A wasp clung on to a lone Hogweed flowerhead swaying in the wind amidst a sea of waving long grass.

There was a sizeable patch of the umbellifer that may be Upright Hedge Parsley amongst dry long grass, but as I photographed the flower it was visited only by a single, quite faded Sun Fly hoverfly.

There were a few Meadow Brown butterflies doing what they do – suddenly flying up in front of you from where they had been basking on the warm earth of the track and heading into the safety of the grass. There were a couple of Gatekeepers too, sheltering from the wind to bask low in the brambles. The one I photographed had a wing-tip missing; maybe a narrow escape from a predator, but such damage can be one of the hazards of territorial scraps and of frequenting thorny brambles.

And just for some colour, Rosebay willowherb, which I always think is quite out of context here, even if it does look pretty. Today at least it was giving nectar to a few little bumblebees.

From the summit the views are always spectacular and today you could clearly see the low clouds skimming the tops of the higher Carneddau mountains to the west and heading our way.

The effect on the seascape was strangely beautiful too. Looking to what is roughly the south-east across Colwyn Bay, the distant hills were obscured by a mist hazeand although the sea appears to be flat calm; the wind was rippling back the surface, giving it texture, while the moving clouds created dynamic areas of light and shade. Mesmerising.

Back to earth I headed across the hilltop to make my way back down the other side. Mushrooms continue to pop up from the short turf and are still being nibbled. I’ve done a bit of research and from their shape I think they are a species of Boletus. This one was encircled by another of my favourite wildflowers of late summer, the lovely and semi-parasitic Eyebright. There are two variations here – plants with flowers blotched wih purple and others the more usual white with yellow centres.

Further down the slope where Knapweed grows in the longer grass, there were a few nectaring insects. A Common Carder bumblebee, a male Red-tailed Bumblebee and a few hoverflies. There was also a badly-damaged Burnet moth that had somehow managed to haul itself up a flower stem to feed, despite having lost at least half of all of its wings.

As I reached the bottom of the hill I stopped by a patch of Hogweed growing right on the edge of the woodland. The clouds finally cleared the way for some sun to shine through, which encouraged out a little flush of hoverflies. There was a lovely fresh female Myathropa florea – mentioned in a previous post as having the memorable and distinguishing ‘batman logo’ marking on its thorax. It was extremely mobile, but clearly hungry and from a distance I managed to get some images showing it from several angles.

Then a treat to end the walk – a petite and dainty hoverfly with black and white markings, another new-to-me species.

This insect was tiny, highly mobile and flying frequently between adjacent flowerheads, so my photo opportunities were few and some of the images I did get were a bit blurry. I’m not sure if its a Leucozona glaucia or similar looking Leucozona laternaria. My book tells me the former are ‘abundant’ in this part of the country and the latter more so here than further east.

Historically August can be quite a wet month and is statistically less likely to have long spells of sunny holiday weather than July. This August of 2016 is certainly following the trend.

August is the traditional month for the harvest in the British Isles, which is the reason it became the main school holiday month. In the past village children were recruited to help with the then labour-intensive process and the first general Education Acts drawn up in Victorian times, providing general primary education for all, took this into account. Even the youngest child could play a useful role in keeping the pigeons and crows away from the gleanings (spilt grains).

August 5th

Finally, this mid-afternoon, having waited patiently all day for an interval of more than half-an-hour without signs of imminent rain, I seized my moment and headed for the hill. Not confident the break in the rain would last long, I didn’t linger on the pathway up through the woods, only stopping to photograph a Sycamore leaf afflicted with Tar-Spot fungus …..

…. and those of a shrubby plant I don’t recognise, well-patterned by leaf mines.

A quick look over the fence on the wood’s edge didn’t look too promising; the Carneddau mountains to the west were veiled heavily by approaching rain clouds.

Incoming rain

I reached the Woodland Trail in record time for me, again stopping only briefly by the big bramble to note any activity on the late flush of newly-opening flowers. Just a male Tree bumblebee and a Meadow Brown butterfly. (It’s fairly easy to spot male bumblebees as they have no pollen baskets and no real purpose other than to eat to stay alive for as long as possible, so they don’t rush about like workers).

I had reached the line of used-to-be-coppiced Hazels when the rain arrived. Fortunately the foliage of the tree canopy is so dense there that hardly a drop got through, so I was kept dry even minus a waterproof. The Hazels here produce few nuts; perhaps because they know their efforts will be squandered by Grey Squirrels; they take them while still green, have a quick nibble to reach the soft kernel inside, then cast them to the ground when they are done.

I waited until I could no longer hear rain on the tree leaves and carried on walking, noting how surprisingly green and fresh-looking the greenery was for this time of year.

However, despite the greenery there are sure signs that this summer is past its peak. In Adder’s Field the Burnet roses are bearing fruits; the hips already dark red although not yet as dark as they will become. The Wild onion flowers are coming to an end and they too are producing fruits; tiny bulbils which will sprout in situ, then drop to the ground and produce roots ready to grow into a new plant.

Stretched vertically between the rose stems was the tightly woven web-tent of a Nursery-web Spider. Peering down to its base I tracked down the weaver to where she was hiding, only some of her legs properly visible. These spiders are quite big and clumsy-looking yet produce such surprisingly fine web fabric; it’s like a piece of silk organza. (Arachnaphobes maybe scroll down quickly now!)

The Wild clematis, or Old-man’s Beard as it will become, is in flower too, another signaller of the slide into Autumn.

On the opposite side of the field the swathe of Hemp Agrimony is in full flower and after the rain, the warming sunshine was drawing out a crowd of insects, literally buzzing with excitement at the abundance of nectar and pollen on offer.

Again, takers were mostly male bumblebees with a few hoverflies and butterflies.

Sightings of Gatekeeper butterflies were top of my wish-list for today. I had already seen a few flying about in the last few days, but was pleased to find my first photographable one of this year. Its tiny size was emphasized by the proximity of a large Red Admiral on a neighbouring flower.

Nearby, ragwort was also working to attract pollinators. A damaged 6-spot Burnet had taken respite on a flowerhead and was still there hours later when I passed it on my way home. There were more male bumblebees, hoverflies and a tiny black-and-white striped bee.

At the top end of the field a patch of umbellifers – tall Hogweed amongst shorter Upright Hedge Parsley.

In previous years I have found a few stems of Red bartsia in flower amongst the long grass at this end of the field; this year there is a significantly larger patch of this interesting semi-parasitic plant.

Given a week or two to finish ripening, a good crop of berries on the Rowan tree should keep the blackbirds going for a while.

Break here to sit on my favourite rock (still slightly damp), have a drink of water, eat a peach and scribble down notes before heading up towards the summit.
