Cormorants flying overhead refocussed my attention and I began the climb up the steep slope to the next level of the cliff.

I didn’t get far before stopping to watch the Whitethroat I had been heading for pre-Chough. He was singing from an old bramble stem close by and was nicely visible apart from being seemingly garotted by a twiggy branch. Song done, he flew across the track into the base of a huge bramble shortly followed in by his mate coming from the other direction, carrying food in her beak. So this is where they are nesting, no doubt tucked low down in the protective thorny thicket.

About half-way up I welcomed the excuse to pause, granted by the sight of another Swollen-thighed Beetle, this time a male sporting a splendid pair of said swollen thighs.

At the top is a reminder that the slope’s purpose was not originally as a walking track. Here stand the remains of supports and cogs for winding gear, once employed to steady trucks full of quarried stone on tracks down the steep slope, then to haul back empty ones.

This quarry face accommodates many nesting pairs of Jackdaws, whose cries often echo loudly around the bare stone cliffs. They were quiet today, the only sound made by a sheep bleating from the edge of the wall towering above. Clearly a mother, she may have been calling for her young one; I hoped he hadn’t been hauled off to market to end up as Welsh Spring Lamb in a butcher’s shop.

I took a very quick look at nesting Fulmars, didn’t want to disturb them so stayed well back.

Attractive birds with an elegant stiff-winged flight, it’s hard to believe they produce such a loud, rather harsh cry and that their tube-like nostrils are designed to allow them, inelegantly, to snort out salty water.

From up here you can look down on the flat quarried-out ‘Level 1’ of the site, with the cove of Angel Bay at its edge. The dry grassed areas are already showing signs of wear and tear.

Onwards and upwards, following the track that is both on the routes of the North Wales Coastal Path and the national Wales Coast Path. It is heavily eroded in parts, and bridged by gnarled old roots, (or branches?) of gorse.

Ravens had made me aware of their presence since arriving here today, being more mobile and noisier than usual and as I ambled along this part of the track an outburst of their calls broke out from somewhere ahead of me. I had just seen birds harrassing what I assumed to be a Buzzard and thought that may have escalated into a bit more of an incident. Getting closer I saw three birds having a bit of a to-do; two of them seemed to be attacking a third that was sitting atop a fence. Not a Buzzard.

I was still too far away to see properly, but this may have been a pair of Raven upset with an intruding one. Does it have something in its beak in the first picture, an egg maybe? I have no idea but they took off from here and continued to express their annoyance from the field below for some time.

None the wiser as to what I’d witnessed I carried on, scanning the track ahead of me, as I am wont to do at this time of year, checking for sheep poo; you never know when there may be something interesting dining out thereon. I got lucky, a fairly fresh deposit yielded a little male Yellow Dung-fly. In an awkward spot to photograph, I had no option than to kneel down in front of the dung, then almost had my nose in it to get him in close up without using the lens zoom, quietly hoping no-one came along the path to witness my odd behaviour. It was worth it; I realised he hadn’t flown off as he was otherwise occupied with a lady Dung-fly. Females are far fewer in number than males, so there was no chance he was leaving, whatever I was doing.

THE CORMORANT COLONY

Reputedly the largest Cormorant breeding colony in the British Isles, this is an impressive sight, even from this distance and this is only a part of it; it continues around to the other side of the rocky outcrop in the photograph below, where there are even more of them.

I’ve shown this aspect of the Cormorant colony several times before, but this is the first time I’ve visited it at the right time to catch the birds on their nests. I was thrilled to get a glimpse of young birds in some of the nests; Cormorants usually lay 2-3 eggs, and from those I could see most seem to have hatched and grown successfully, so there must be plenty of food available locally to keep offspring and parents well fed.

Some of the young birds seemed a bit more advanced than others and were already out of the nest exercising their wings, but many birds were still sitting.

The bulk of the colony is not as easy to see, and viewing the birds involves a bit of rambling up and down the uneven cliff top, then peering down from cliff edge, but it is well worth the effort. The photograph below shows the colony to be situated well out of reach of nosy people.

Around the rock I was now upwind of the birds, so as well as amazing sights and sounds I was greeted with the equally amazing smell produced by a large number of fish-eating birds confined to a relatively small space. I wish I could share it with you!

But pungent aromas aside,the colony on this side holds another treat; right in its centre is another smaller colony – of smart little penguin-like Guillemots. Surrounded by the much bigger Cormorants I imagine it is a safe haven for them from potential predators such as gulls and the Cormorants seem perfectly accepting of them.

Cormorants and Guillemots sharing fishing space on the rocks below. There were many more birds of both species flying back and forth and hunting and diving in the water too. Cormorants stay separate but Guillemots often join together in ‘rafts’ floating on the surface of the sea.

These two birds, who I fancied were enjoying some fresher air away from the colony, is my favourite Cormorant image from the day. The birds weren’t making a sound; they gape their beaks as a means of cooling down their bodies, but it seems like they’re commenting on something out at sea. Possibly the ever-encroaching turbines of the wind farm, or maybe they were sureying for likely fishing spots. 

It was a sunny day with some cloud and really strongly windy, particularly noticeable up here at the top of the headland on its sea-facing edge, but the elements’ combined effects on the water was breathtaking. I sat for some time watching the ever-changing patterns of light and shade on the surface of the blue sea as the wind rippled across its surface and clouds cast shadows above it. It really was the colour of the photograph below and quite mesmerising.

View from the Little Orme across Llandudno Bay to the Great Orme

Birds flew past the cliff at eye level; mostly Herring Gulls, but one Greater Black-backed gull too, and a Raven gronked a greeting as he passed by; all strong birds gliding effortlessly on the wind and thermals created by the cliff face. A Rock pipit popped up over the edge briefly but popped down again when he spotted me. A Jackdaw also appeared over a ridge, but disregarded me completely and carried on foraging within touching distance, even posing for a portrait.   

THE CLIFFTOP

Returning to the main track I passed a ewe and her lambs who had found a shady and sheltered place to rest with her lambs.

I watched a 7-spot ladybird scrambling through the mossy turf. Grazed by sheep and rabbits, baked by the sun and exposed regularly to strong, salt-laden winds anything that survives here has to be tough, especially the flora. Amongst the toughest of our native flora are the thistles, the two most common species of which thrive here.

The Creeping thistle has already begun flowering and even up here was being visited by bumblebees and a wind-blown Red Admiral butterfly.

The other is the fierce-looking Spear thistle with its aptly-named long sharp spikes protecting its every part, which has flower buds almost on the point of opening now.

On the ledge beneath an overhanging rocky outcrop I was surprised to spot a clump of white-flowered plants. Getting closer I saw they were Sea campion and also Moon (Ox-eye) daisies with one of the best specimens of Salad burnet I’ve seen anywhere so far this Spring. I wonder how they got there?

Sea campion – Silene maritima

Going back down I took a photograph to remind me to say that although fading fast there is still gorse in flower and also hawthorn, but the main blossom plant now is the creamy white elder.

And another to remind myself that I can never tired of looking at this view across Penrhyn and Colwyn Bays, even when on hot days like this one much of the distance is lost in a haze.

Little Orme Level 1

May 27th

The Little Orme was physically scarred and shaped by human demands and quarrying activities during the first half of the last century. Subsequently handed back to nature and a testiment to its incredible ability to regenerate, an interlocking patchwork of habitats packed into a compact space on varying levels have become a haven for a diversity of wildlife, particularly wildflowers, birds and insects. Now in part a Local Nature Reserve with areas set aside as SSSIs, its wildlife may again be under pressure as the headland is an increasingly popular recreational area for local people and visitors and is also crossed by walkers following the Wales Coastal Path or the North Wales Coast Path. 

I was here today with the intention of taking some photographs of the Cormorant colony in mind. The birds are well into their breeding season now and have well-grown offspring in their nests and I wanted to catch them there before they fledged. I thought I was focussed on the job in hand, but as anyone that has ever been out walking with me would have guessed, it took less than two minutes for me to be distracted from my mission; firstly by a Harlequin ladybird guzzling aphids on the going-to-seed Alexanders, then by a lovely shiny metallic green female Swollen-thighed Beetle – Oedemera nobilis, who confusingly doesn’t have Swollen thighs at all, it’s the males that sport them as emblems of their maleness, the thicker the better in their bid to secure mates. She was perfectly displayed in the cup of a perfect dog rose, like a little jewel.

The cliff path along to Angel Bay took a while to negotiate too. Its sea edge is lined with masses of Red Valerian in all of its shades from deep carmine through pinks to white and it looks lovely.

I know it’s not a native and crops up anywhere and everywhere, but here it doesn’t look out of place and it is great for insects like the Painted Lady I found nectaring there.

There are native wildflowers on this cliff edge too, including some good sized patches of Wild Thyme and the pretty pale lemon-yellow Mouse-ear which has colonised a large patch of the crumbly downslope of the cliff.

There’s a lot of Horsetail here too, I’m not sure of the species. It also cascades down the cliff where it looks a bit like a new plantation of tiny Christmas trees. A bit further in from the edge was a large patch of what I thought was Ground Ivy, but am now not sure about; very short-stemmed here on the dry exposed cliff and a mass of purple flowers, I will go back and check.

The Little Orme is the place to visit if you love your Corvids as I do. Ravens, Crows, Magpies, Jackdaws and occasionally Chough are all here. Seeing or even hearing ravens early on in a visit here always sets the mood for me, reminding me that despite the fact that this is now a place much used for recreation by people and their pets, it is still clinging on as a wild habitat. A pair flew overhead, ‘gronking’ as they did so and landed high up on the edge of the cliff, in the centre of the image above, one of their habitual lookouts for surveying their Kingdom.

Next a Magpie caught my attention as it landed on a bramble patch on the cliff edge, leaving quickly with an insect in its beak.

Then Jackdaws, great numbers of them nest in close colonies on the quarried-out cliff faces. Once breeding is over they disperse during the day, although plenty stay and forage around the grassy clifftops and it’s a safe haven to head back to and roost at night.

At the sea end of this first flat level there’s a little bit of original rock remaining, separating Angel Bay from Penrhyn Bay and forming one side of the little cove that is the haven of the Grey Seals often mentioned in my posts. The sea-facing ledge behind said rock can be a good place to look out for birds at sea, especially in the autumn and winter, but today it was bees I found there. I have to admit I thought they were wasps as there were several that were flying around, and once or twice, in and out of holes made by mining bees. A quick check with the wise ones at BWARS (Bee,Wasp & Ant Recording Society) though, told me they are nomad bees, Nomada goodeniana, that seek out other bee’s nests in which to lay their eggs. They are apparently quite a common species, but a first for me.

A local speciality (botanically that is, not on menus!), Wild cabbage grows here, there have been bluebells on the cliff slopes and I spotted the bees as I stopped to photograph a pretty Bloody Cranesbill flower.

Looking out over the cove, there were just a couple of seals in the water and a sizeable gang of cormorants perched up at the sea end of the headland.

 

The sight of those Cormorants spurred me on to get back on track towards their nesting site. But first a stop to admire the Thrift, perhaps my favourite coastal wildflower which despite all the hazards is thriving here.

I am finally almost at the bottom of the steep slope up to the next level of the old quarry. I was following the sound of a Whitethroat singing when from close by a black bird took off and flew away from me back in the direction of the site entrance. Something in its gis made me watch carefully to see where it would land; its upturned wingtips showed this wasn’t a crow or a jackdaw and then that distinctive call confirmed I was chasing a Chough.

Chough fly with upturned wing tips

It landed a short distance away and set about digging in the short turfy ground in pursuit of food with its long curved bill. It was a ringed bird, banded on both legs, but perhaps not quite an adult as its beak was a dark orange colour rather than the bright red of a mature adult.

Chough eat worms, caterpillars, ants and are particularly partial to the larvae of dung beetles

The bird had picked a productive spot and was so settled into its feeding it took no notice of me sitting watching it from a conveniently sited bench. But foraging close to the junction of two of the main tracks across the clifftop it was inevitable that it would be disturbed sooner rather than later, and so it was, taking off and flying off over the sea and around the headland. That was definitely my best ever Chough encounter here in North Wales; certainly the closest. And I would have missed it if it wasn’t for my slow- walking meandering habit.

Next Level of this trail to follow shortly…. there will be Cormorants!

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?

160807-LTLORME (45)-Large White female nectaring

160807-LTLORME (36)-Large White flyingThe 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’.

August 7th

160807-LTLORME (43)-Large White front view2016 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!

160807-LTLORME (34)-Wild Cabbage plant

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.

160807-LTLORME (62)-Large White (f) nectaring on bramble

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 160807-LTLORME (37a)-Lage White nectaring on brambleundersides 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.

More Signs of Summer Passing

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.

160805-Bryn Euryn (78a)-View

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.

160805-Bryn Euryn (101)-Incoming weather

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.

160805-Bryn Euryn (110a)-Mushroom with Eyebright-Euphrasia micrantha

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.

160805-Bryn Euryn (184)-Leucozona on Hogweed

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.

160805-Bryn Euryn (23)-steps up to field

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.

160805-Bryn Euryn (61)-Red Admiral front view

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.

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.

Butterflies of the Great Orme

July 14th – Great Orme

The great bulk of the west face of the Great Orme rises steeply from the shore of the Irish Sea; its scarred and fissured face testament to centuries of the relentless onslaught of invading weather fronts. Glancing upwards from its base it looks intimidating, barren save for a few patches of eroded grass and seemingly hostile as habitat for anything save the odd nimble Kashmiri goat. However, as in the best tradition of myths, legends and fairystories, looks can be deceptive and here-upon, not too far away, lies a magical kingdom populated by tiny beautiful creatures.

160714-Gt Orme 3-West Beach-Cliff face & toll house

The toll house on Marine Drive marks the beginning (or end) of the cliff path

The creatures take the form of butterflies. Two diverse species have evolved and adapted themselves to survival in this unlikely place and have been recognised and classified as ‘sub-species’. One is a variant of the rare Silver-studded Blue, classified as Plejebus argus ssp. Caernensis and the other a variant of Hipparchia semele (Grayling), classified as (ssp.Thyone). Both are ‘dwarf races’ and considered to be endemic to the site.

The ‘butterfly kingdom’ spills into the Great Orme or y Gogarth Reserve owned and managed by the North Wales Wildlife Trust, which has no paths, but there is a narrow stony path along a ledge cut about a third of the way up the cliff, which is indicated on the photograph above as a line of wire netting that both marks its edge and keeps people safe and goats in. I walked alongside the West Shore from the town end and joined the path at the back of the Toll House, but if you are coming down from the other direction, the other end of the track is waymarked to your left. A word of caution – this is a very narrow, unevenly surfaced track, so take care.

The day was sunny but windy, conditions which bring out the butterflies but often keeps them low to the ground or amongst long grass stems. I wasn’t expecting to start seeing the little Silver-studded Blues as easily as I did, but there on a patch of red valerian below the ‘dangerous cliffs’ sign I spotted my first ones. Most were looking rather worn and a bit tatty, but I was happy to see them at all.

As I watched I spotted a pair coupled together who were then joined by two others with another fresher-looking male also heading their way. Unlike their cousins, the Common Blues, these smaller butterflies don’t zoom away at speed just as you’re about to press the shutter button, but flutter gently from place to place, tending not to fly any distance away. They seem to bask quite frequently.

The uppersides of males are a glorious vivid blue with a dark border. Females’ uppersides are browner with a row of orange spots; in this sub-species they also have a variable flush of blue that extends over the hindwings and the base of the forewings. The Silver-studded Blue takes its name from the light blue reflective scales found on the underside of most adults and which are quite visible when light reflects off them in fresh butterflies, but they wear off quite quickly as the butterfly ages and can be quite difficult to see. In the main, the undersides are a brownish-grey with black spots, a row of orange spots, and small greenish flecks on the outer margin.  Males are similar to the Common Blue, which lacks greenish spots.

The Silver-studded Blue is a Priority Biodiversity Action Plan (BAP) species.

Generally they are found in close-knit colonies, most containing less than a thousand adults. Here on the Orme numbers fluctuate over the season, but may rise to a peak of a thousand or more. Today I met a warden and an assistant on the path that were assessing current numbers – in one spot alone they had counted 130 individuals, so despite the recent inclement weather, they appear to be doing OK.

The number of Graylings I saw also took me by surprise; in other locations I’ve been more than happy to come across the occasional one; along this path I encountered a good few patrolling the path. I’m hesitant to give a number as I have no idea how many times I might have seen the same one as it circumnavigated a territory. It could well be that the same one or two were circling me!

Hipparchia semele ssp. Thyone (Thompson, 1944)

H. semele ssp. Thyone flies earlier than is usual with other races of Grayling, being on the wing towards the third week in June, and disappearing by the end of July.

160714-Gt Orme 57a-West Shore-Grayling

I am not practised enough to be able to recognise subtle differences between species & sub-species of butterflies and have no desire to catch any to compare them, so I have taken points from Mr Thompson’s comparisons:

Hipparchia semele ssp. Thyone

♂ Strikingly smaller than any other British race of semele. Coloration is more uniform than in typical semele, with the pale areas more ochreous. Forewing spots are smaller than in other races, with the lower of the two frequently absent. Underside coloration duller and less contrasting than in the type, with the white areas of hindwings tinged with ochre. ♀ Also smaller than other races. Spots are smaller than in normal specimens.

The special butterflies were not alone here. In  a small sheltered quarried out area at the side of the track more red valerian was attracting some larger visitors. I was most thrilled to see a Small Tortoishell, only the second I’ve seen this year and the first to stay put long enough to photograph.

There was a Red Admiral there too, a few Meadow Browns and a single Dark Green Fritillary that was repeatedly chased away by Graylings.

Another first sighting for this year was a Cinnabar Moth. I was musing just the other day about why I rarely see the adult moths when the distinctive yellow and black caterpillars are so numerous at this time of year; perhaps they don’t over-winter well? It was tricky to get even this less-than-brilliant image as it was fighting against the wind trying to stay on the cliff edge.

Things Bright and Beautiful

July 3rd – Bryn Euryn

Adder’s Field

Frothy sunshine-yellow Lady’s Bedstraw brightens the grass and on this warm sunny day scents the air with the delicate fragrance of fresh-cut hay.

160703-Bryn Euryn (19)-Lady's Bedstraw

160703-Bryn Euryn-Lady's Bedstraw

Lady’s Bedstraw-Galium verum; Welsh-Briwydd felen

Flowering: June to September

Medieval legend has it that the Virgin Mary lay on a bed of Lady’s Bedstraw in the stable of the inn in Bethlehem, as the donkeys had eaten all the other fodder. It is from this legend that the common name for the plant was taken, and also led to the belief that a woman lying on Lady’s Bedstraw would have a safe and easy childbirth.

Lady’s Bedstraw is a plant of dry grassland, dry banks, downs and old established sand-dunes.  On warm sunny days the air surrounding the frothy yellow flowerheads is deliciously fragranced with the scent of lightly perfumed fresh hay. Lady’s bedstraw is a food source for the huge Elephant hawk-moth caterpillar, then is favoured by the adult moths as a rich source of nectar. The migrant Humming-bird Hawk Moths are attracted to it too.

Lady’s Bedstraw was once one of the most useful of the meadow flowers; it was commonly used as a ‘strewing herb’, a natural form of air-freshening and for stuffing mattresses.  In the north of England the yellow flowers were once used to curdle milk, giving rise to several associated names such as cheese rennet and cheese renning. The leaves and stems yield a yellow dye and the roots a red dye; it was said that when cattle feed on it, it reddens their bones.

Lady’s Bedstraw contains the chemical coumarin, used in the drug dicouramol, which will prevent the blood clotting. In herbal medicine it was claimed the herb was a remedy for for urinary diseases, epilepsy and gout.

Up here on the near-summit rocky cliffs I spot a single lovely Grayling. It settles on a warmed rock close by and I manage to catch it before it folds away the orange markings on its upper wings.

160703-46-Bryn Euryn-Grayling on my shoeI am fascinated by the butterfly’s cryptic camouflage, its ability to melt into the rocks it settles on to bask. If I take my eyes off it I have to wait until it flits off again to relocate it. Unless it lands on my shoe!

I was keen to get a good number of shots of this obliging subject, as in this location at least their appearances are not always predictable.This year I’ve had a few sightings, last year none at all. After a few minutes of following it from rock to rock I realised the butterfly had no immediate plans to go far, so I relaxed a little and sat for a while on a patch of grass.

There’s a whole other realm cuched down in these often- dry grassy-rocky areas. In the little patch where I chose to sit Common Milkwort was growing through Wild Thyme in a rocky crevice and nearby the tiny yellow dots of a creeping Hop Trefoil marked its presence, punctuated with taller purple-leaved Eyebright.

I spotted a bright yellow-green beetle scurrying through the vegetation, thinking this must appear to him to be a veritable jungle. I had wondered what Sulphur beetles got up to when not gorging on hogweed.

There were large mushroom-like fungi growing amongst the grass here. Many were clearly being eaten by something – voles, mice? Maybe even slugs or snails.

Then, further down the slope, the very thing I had been crossing my fingers hoping to see- a flash of orange that was a Dark Green Fritillary taking off vertically from a Common Orchid.

There is a small colony of these lovely fritillaries here; the most I’ve ever seen at the same time in a season was 10-12. That year the Knapweed and Scabious they prefer to nectar on, were more fully in flower than now . Thus far I have seen only two at the same time. Today there was just the one. I hope there are a few more to come. The butterfly returned to nectar on one of a few Knapweed flowers fully opened. It shared the space with a chunky insect I am trying to find the identity of.

The fritillaries are large, fast flying and tricky to approach. Sensibly they have also based themselves within a particularly brambly, steep and uneven part of the hill that restricts access. That means grabbing images as and when you can – but I like that, it keeps them ‘real’, so you see the butterfly as I did – mostly through a grass curtain.

5/6/16 – Pyramidal Orchid – first sighting of 2016

I photographed my first sighting of a Pyramidal Orchid on June 5th, where it was growing through a complimentary patch of Common Rockroses. Since then they have come on apace and there are many more showing their beautiful heads amongst the long grass that fringes the summit of the Bryn.

July 3rd

Ten days later the rush of blooms had slowed and whilst there were still a good number to be found, they are more scattered and most significantly smaller than the earlier ones were.

Pyramidal Orchid– Anacampsis pyramidalis; Welsh – Teigeirian bera

This orchid may be found flowering from early June through to early August, but here it is definitely at its peak now and flowering abundantly.

In general, the Pyramidal Orchid is found on grassland, usually on lime or chalk, but also on dunes. It is locally common in most of Britain, but rare in Scotland.

Pyramidal Orchid

The plant is so-named for the shape of the flowerhead: a workaday name for such an exotic-looking bloom I think, although it does help to distinguish it from the Fragrant Orchid, with which it may be confused.

The plant’s success and abundance may be due to its relationship with insects. Each flower has a long thread-like spur that holds a generous supply of nectar that attracts day and night flying butterflies and moths. When the nectar is accessed, modified stamens stick to the tongue of the insect that straighten during the insect’s flight and are then pushed directly onto the stigma of the next flower visited. This results in viable seeds being produced in 95% of the flowers.

Crossing the hill’s summit and walking through the ‘downland’ area, more Orchids are blooming prolifically, these being Common Spotted Orchids.

Flower spikes of plants on Bryn Euryn vary in colour. Most are this lilac-purple colour, others are white with a few in shades between.

The flowers vary from white to pale or dark purple and are patterned with dots or small blotches of a darker purple.

The leaves are narrow and usually dark-spotted.

Butterflies and more rare treats

June 5th

One of the most fascinating, and sometimes a little frustrating thing about observing wildlife is that no two days, even in the same location are ever the same. I know that, but I had to retrace yesterday’s steps in the hope of further sightings of a Dingy Skipper or two didn’t I?

Along the Woodland Trail, Speckled Woods seemed  even more numerous than yesterday, and a little more willing to bask with open or partially open wings.

Speckled Wood

Leaving the shelter of the trees and entering the open meadow there was a fairly strong, cool breeze blowing – not the best of conditions for photographing butterflies that tend to stay low in the grass on such days, despite today’s sunshine. That didn’t deter me from stubbornly attempting to get some images of a lovely fresh male Common Blue. It was highly mobile, but during their frantic circuiting, these butterflies frequently return to the same spot to settle for a breather and luckily this was the case with this beauty; he favoured this particular grass stem or a nearby head of clover, so I waited there and eventually caught him during moments when the breeze briefly stilled. Not as sharp an image as I’d like, but a record.

I wondered if I might see the little green jewel beetle again. Last night, looking for information about this species I read they favour yellow compositeae flowers and remembered there were a few hawkweed plants close to where I found it yesterday. Lo and behold, I found not just one there, but a mating pair. I’ve put in two images of them, one to show their real size and another enlarged one to show how beautiful they are.

After a few minutes of photographing the obligingly oblivious pair I noticed a female Swollen-thighed Beetle -Oedemera nobilis (females don’t have the swollen thighs of the male) that had landed on a nearby flowerhead.

She decided to take a closer look at what the mating pair were up to. (Sorry about blurry image-swaying flower stem!)

I couldn’t resist this patch of pretty Common Daisies in the long grass.

A slight variation on yesterdays route took me up the track that comes out the other side of the hill. It was even breezier up there, but there were insects about taking advantage of the nectar and pollen on offer from the abundant wildflowers, mainly Rock-roses and clovers.

This side of the hill’s summit was looking beautiful, carpeted with sunshine yellow Rock-rose and Bird’s-foot Trefoil.

I stood still for a few minutes scanning the flowers for butterflies. Small Heaths  were most numerous, but I did spot a single Dingy Skipper. Living up to its name, it was skipping around randomly at speed, too fast and mobile for a photograph, but at least I’d seen it. I had more luck with a lovely little iridescent green Forester Moth that landed on a Salad Burnet flowerhead and stayed there.

160605-BEMTH-Forester moth on Salad Burnet 3a160605-BEMTH-Forester moth on Salad Burnet 1

There are three similar species of Forester Moth in Britain that can be difficult to tell apart, but I think this one is a Cistus Forester-Adscita geryon. According to the Butterfly Conservation info: “This species is generally smaller than the Forester or Scarce Forester and the presence of good quantities of the Cistus Forester’s foodplant, Common Rock-rose, can be a useful indication of this species.”

Now for the ‘rare treat’! Since I came  to live here, I have been looking out for a ‘Nationally Scarce’ plant that is recorded as growing here, the fascinating Nottingham Catchfly-Silene nutans. I’d only seen pictures and read about it, imagining I would find it in a rocky place on the cliffs or in bare ground. But, much to my amazement and delight, I found it today well-hidden amongst lush long grasses near the edge of a track. Getting my eye in, I saw there were several smaller clumps of the plant further back from the track edge, so clearly a good year for it. Difficult to photograph in the strong breeze, I’ve edited and sharpened my images a little so the plant is more visible than it was on the day!

160605-BE1256-Nottingham Catchfly (5)

Nottingham Catchfly amongst swaying long grasses

The plant is so-named because it was first found on the walls of Nottingham Castle. It no longer grows there as the site was destroyed during work done on the site in the 19th century. The flower remains the County Flower for Nottinghamshire though.

160605-BE1256-Nottingham Catchfly (4)

The plant is vespertine like many of the catchflies. This means that the flowers tend to stay closed in the daytime and open in the evening or at night, when they release a heavy scent into the evening air in order to attract night-flying insects and moths.

160605-BE1256-Nottingham Catchfly (3)

Flowers are drooping, in very open clusters and all usually pointing one way. Petals white above, greenish or pinkish beneath.

Each flower opens over three successive nights revealing one whorl of stamens on the first night and another on the second and the styles on the third. This is thought to prevent self fertilisation.

160605-BE1256-Nottingham Catchfly (2)

Moving on up to the summit I found my first Pyramidal Orchid of the year, still tightly in bud.

Back in the same spot as yesterday I got another brief glimpse of a Dingy Skipper nectaring on Bird’s-foot Trefoil.

At the bottom of the ‘downland’ slope I finally caught up with a Small Heath on a buttercup.

The first week of June was full of the promise of a glorious summer to come. A  run of warm sunny days had brought forth perfect and prolific blooms and began to coax out the butterflies.

June 4th

Along the woodland trail that circuits the lower slopes of the Bryn Euryn Nature Reserve, the early summer wildflowers are peaking. Foxgloves are at their perfect best, with stems full of open blooms graduating upwards to buds. There are not many plants on this site, but they seem to be gradually increasing in number year on year.

Honeysuckle is blooming prolifically, the best I have ever seen it and it smells heavenly.

The wild strawberry patch is also full of flowers, promising a bumper crop to come,although it is in danger of becoming overwhelmed by encroaching ivy and other vegetation.

Birds were heard but not seen, concealed by the dense foliage of the tree canopy; Chiffchaff, Wren, and Blackbirds were all still singing between nesting duties.

Some of the clumps of grass that grow along the woodland tracks are flowering now. This is False Brome-Brachypodium sylvaticum, a perennial grass common in woodlands where it prefers the shade of the canopy.

One of the more severe winter storms brought down three Scots Pines. Two have been sawn up and cleared away but the largest has been left where it fell and poignantly continues to live, now producing new cones.

Beautiful fresh Speckled Wood butterflies were out in number and busy patrolling territories or sitting on leaves, wings closed in wait for intruders or potential mates.

Up the steps and into the small open meadow the first impression was of lush greenery. The grass is growing long and closer inspection reveals it is studded with purple and white clovers, yellow Common Rock-rose and buttercups and the curiously flowered salad burnet.

Along the edge of the tree-line another burnet, the beautiful Burnet Rose (visible centre left of the photograph above) is also in full flower. It too smells divine and was absolutely buzzing with a variety of bumblebee species revelling in the pollen and nectar bounty on offer.

In previous years I have noted that the Burnet roses have played host to a bright orange fungus, this is Rust fungus Phragmidium rosa-pimpinellifoliae. It doesn’t appear to harm the plants, but this year the fungus is almost as prolific as the blooms themselves.

On the small rocky outcrop at the top end of the field there are pretty clumps of Common Rock-rose-Helianthemum nummularium.

160604-BE31-Shiny emerald beetle

Cryptocephalus aureolus

A glint of emerald green drew my attention to a tiny shiny beetle in the centre of a Rock-rose flower. This little Jewel beetle doesn’t appear to have a Common name, so is known by its Scientific name of Cryptocephalus aureolus. The generic name of the beetle and its relatives refers to the insects’ heads being hidden under the pronotum. This is a new species recording for me here on the Bryn, which is not to say they haven’t always been here, just that I hadn’t seen one till now

I saw some little butterflies from here, a couple of Common Blues and Small Heaths, but all flying low in the long grass and in no mood to settle to pose for portraits.

Onwards and upwards along the Summit Trail, taking the track that comes out at the bottom of the steep ‘downland’ slope. This is often a good place to find Common Blue and Brown Argus butterflies, but not today, although there were a good number of Small Heaths to be seen, again not settling for me.

I progressed fairly slowly up the steep slope and near the summit was  attracted to a sheltered corner backed by trees, bordered by raspberry brambles and where the ground was covered by Common Rock-rose and Bird’s-foot Trefoil flowers. I was drawn there by the sight of a small brown butterfly, which I hoped may be a Brown Argus, but which turned out to be a female Common Blue.

Then I noticed a slightly larger brown flutterer that I thought at first was a moth. A closer view changed my mind, this was a butterfly and although it was rather faded and a bit tattered round the wing-edges, was the right size and shape for a Skipper. Old records for the site indicate the presence of the Dingy Skipper-Erynnis tages, whose common name may not inspire much excitement, but this is a fairly uncommon butterfly in the UK, with recorded sightings at sites in North Wales not exceeding low single figures. I hope now my ID is right – if anyone knows better, please let me know!

Dingy Skipper

I’m sure I’m not alone here, but I get nervous when I’m confronted by a new-to-me species of anything; especially when I’m aware this may be my one and only chance to record a sighting. So, I find I hold my breath, begin to panic slightly that I won’t get a photograph that will help me confirm its identity back at home and pray no-one will pass close by and disturb my target. My ‘technique’ thereafter is quite basic – to start from a distance and gradually move in closer, capturing as many images as I can before my subject takes off!

This particular butterfly was not making things easy and was restlessly flitting about amongst the flowers, staying low to the ground and frequently hidden amongst the plants. I felt quite dizzy staying focussed and following it around, probably down to lack of oxygen intake from the not-breathing. As ever, I would have liked more opportunities for photographs, but did manage to get a couple of fairly clear images that at least have given me my sighting record.

After a few moments the butterfly took off away down the hill and I lost track of it. The camera battery also chose that moment to expire and as this had been a spur of the moment, travel light walk, I had no spare with me!

I have written detailed posts about many of the subjects mentioned in this one, so rather than repeat myself, I have added links to click onto if you would like to see more about any of them.

‘But it is the common species that keep the living world ticking over and provide most of our experiences of wildlife, and I would argue that maintaining the abundance of these is as important a conservation priority as maintaining the existence of rarities’. Richard Mabey
