In UK waters Grey Seals breed during the autumn. Although the entire breeding season spans approximately 8 weeks, individual females will spend 18-20 days ashore, during which time they each bear and suckle one pup. Towards the end of lactation they come into oestrus, as soon as 16 days after giving birth, and are mated.

August 28th

Another windy day on the headland of the Little Orme, but sunny too and the tide was out. Perfect conditions for seeing Grey Seals hauled out on the small pebbly beach of Angel Bay.

Angel Bay is an inlet on the Little Orme’s Headland on the North Wales Coast. Known locally as Angel Bay, on Ordnance Survey maps it is named in Welsh as Porth Dyniewaid.

Spotting one a short distance offshore in Penrhyn Bay was encouraging. The seal was suspended in the water with just it head above the surface facing towards the shore. They do this often and I’m sure they are ‘people watching’, as curious about us as we are about them.

There were boys in the bay, enjoying themselves greatly by jumping off rocks into the calm sea. I’m sure they were unaware of the seals not far away from them, hidden from their view as they were by an outcrop of rock . Unwilling to risk venturing ashore as they would normally have done, some were making the best of small islands of rock uncovered by the low tide, hauling out their bulky bodies to enjoy the warmth of the sun. Unfortunately there wasn’t room for all of them and some were left to drift around keeping a watchful eye out for a space to become available. Grey Seals are the largest breeding seals we have in the UK and those on view were definitely large, quite possibly pregnant females as they do congregate at traditional pupping sites in the autumn.

One had secured a rock of her own. She was rather beautiful, wearing a mantle of silvery grey velvet.

These three were more sociable and had left room for another.

After a bit of heaving and hauling the smaller one squeezed in, but there was no room left for more boarders.

There are nine seals in this picture – 6 on rocks and three swimming around hopefully.

The driver of one of the jet boats that take out sightseers from Llandudno pier spotted the seals and pulled in so people could have a closer look and take photographs of the seals. He must have passed the info on to other drivers as another boatload arrived a few minutes later. Then another who was a bit more intrusive and that got too close.

As the boat was leaving I took a short video as it is unusual to see the seals awake and moving, although they still weren’t doing much. Perhaps because they were rather put out about their lack of space the seals were quite vocal too, although most of the noise here was made by the departing boat & the wind!

An hour or so later the smaller rock had been taken over by a much larger seal; poor thing looks like she’s about to burst!

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.

Large White butterfly (male)

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

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.

: Male flying in

: Male approaching female

: Male approaching female to mate

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.

Red Bartsia

Berries of Lords & Ladies

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.

Upright Hedge Parsley

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).

Tree Bumblebee (male)

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.

: Damaged 6-spot Burnet

: Male bombus praetorum

: Small striped flower 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.

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.

First sight of a worn and battered female

Mating pair attracted others

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.

Silver-studded Blue male

Silver-studded Blue female

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.

160714-GO-Silver studded blue underside (s) 3

Weathered male mating with a fresher female

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.

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.

Cinnabar Moth

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.

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.

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.

Summit Cliffs

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.

Grayling –Hipparchia semele

I 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!

Eyebright with purple leaves

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.

Dark Green Fritillary-Argynnis aglaja

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.

A thick-headed fly-Sicus ferrugineus

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.

Bramble flowers are an important source of nectar and pollen for many species of insects and today, a large tangled patch of blackberry brambles in a sunny spot on the sheltered Woodland Trail was alive with an array of bumblebees and hoverflies.

Hoverflies

Since living here I have begun to recognise the most obvious and more commonly-occurring species of hoverflies, and they don’t come much bigger or more obvious than the handsome Pellucid Fly (Volucella pellucens), aka the Great Pied Hoverfly. This is one of the largest most obvious and recognisable of our British hoverflies.

Myathropa florea

Yellow-and-black stripes are the well-used livery of many hoverfly species and sorting out the different species accurately, especially the small ones, requires more skill and knowledge than I have at the moment, or at least some crystal clear images of certain parts of them.

Bigger yellow and black species are a little easier, especially if they have good clear markings, such as sported by this new-to-me, or at least newly identified Myathropa florea (no common name). I was aided and amused in this ID by a tip from the author of my Hoverfly bible¹, who suggests that the lower marking on the thoracic dorsum (part behind the head) resembles the Batman logo. Well, in a nice fresh clearly marked individual it does!

One of the only small hoverflies that is unique and distinctive in its markings and has earned a common name is the Marmalade Fly Episyrphus Baltaetus. This one was hovering at just about my head height, darting hither and thither in a patch of sunlight in defence of his territory. The image of him in the photograph is still bigger than he was.

Bumblebees

There were bumblebees aplenty, mostly Red-tailed, White tailed and Common Carders, but also Tree Bumblebees and a few little Early Bumblebee workers.

Tree bumblebee-Bombus hypnorum

The number of Tree Bumblebees here has increased greatly over the last few years. I used to see them mainly in early Spring in the Quarry field on Green Alkanet flowers, and maybe the odd one or two further afield. Now they are present in all parts of the site and can be spotted on an array of flowers through to the end of the summer.

Not bramble related, but a special treat was a very brief encounter with a Grayling. On the track up to the summit it literally landed in front of me, sat on a small rock for a few seconds then took off into the breeze.

Grayling-Hipparchia semele

The same strong breeze that carried away the Grayling was keeping the Small Heaths tucked down in the grass, but I finally managed to get an almost-clear view of one feeding on Wild Thyme.

Small Heath-Coenonympha pamphilus

Walking back down through the woods on the way home, a Red Admiral startled me when it flew up from a bramble at the side of the track. It settled back down when I stopped, then flew out again – the feisty thing was deliberately warning me to get out of his space! He sat brazenly on a leaf at about my eye level and reared up defiantly as I approached with the camera, not giving an inch and I’m sure trying to stare me down! Loved his attitude.

June 20th-Rhos Point

13.34- A sunny day with a strong breeze made it feel cold, but I was in need of some quick-fix fresh air and for that, Rhos Point is the perfect spot. It’s also one of my favourite spots for watching wading birds, although I don’t visit it much during the breeding season as it is almost deserted by birds and becomes uncannily quiet. Today I arrived as the tide was coming in and I spotted a small group of Oystercatchers waiting patiently for today’s incoming lunch, so I waited too to see if they would be joined by others.

As I made my way down nearer to the shore I heard some lively chirruping emanating from a shrub that has taken hold on the promenade edge, then a few House Sparrows flew out and headed for the shore below to forage amongst the exposed rocks.

Two elegant Sandwich Terns flew low over the sea, close to its edge.

13.37 pm – Oystercatchers on the sea edge use the waiting time to rest or preen.

Oystercatchers are high on the list of my most favourite birds, they have great character and charisma and the more I learn more about them the more fascinating they become. They are large wading birds and when not resting are noisy. They sport large long orange or red bills, which they use for smashing or prying open molluscs.

The diet of coastal oystercatchers is varied, although dependent upon coast type; on this rocky shore with its extensive mussel beds, they will prey upon mussels of course, and also on limpets and gastropods. They also take advantage of whatever the tides bring in such as small fish and crabs.

The shape of this bird’s bill shows it to be a ‘hammerer’

The bill shape varies according to the diet. ‘Stabbers’ feed by jabbing their laterally compressed bill tips in between the valves of a mussel’s shell, while ‘hammerers’ crack open mussel shells by pounding on them. Those birds with blade-like bill tips pry open or smash mollusc shells, and those with pointed bill tips tend to probe for worms.

13.40 – The Oystercatchers were joined by a beautiful Sandwich Tern.

The Sandwich tern is a summer breeding visitor, returning to north-west Wales & Anglesey from late March to September. In the UK, many of the important colonies survive because they are on nature reserves.

This is a very white tern, which in summer breeding plumage had a full black cap on its head. The bill is long and black with a diagnostic yellow tip. The legs are short and black and the tail short and forked. In flight it shows grey wedges on its wings tips.

13.44- A small number of Curlews flew in to land on the rocky sea edge, where their cryptic plumage allows them to all but disappear.

I took this short video as the Curlews arrived – coudn’t avoid the wind noise!

The curlew is the largest European wading bird, instantly recognisable on winter estuaries or summer moors by its long, downcurved bill, brown upperparts, long legs and evocative call.

13.47- The mysterious moment that suddenly galvanises waiting wading birds into action arrived and triggered most, though not all of the Oystercatchers to begin foraging in earnest.

13.48- A Herring gull arrived to join the party.

13.52- A second Sandwich Tern flew in, closely followed by a third.

The terns also settled down to preen.

13.59- A Cormorant flew past at speed.

14.04- A Herring gull- it’s good to see them down here, where away from the rooftops, rubbish tips and promenades they are not upsetting anyone!

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 and shadow

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.

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!

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.

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.

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.
