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

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

August 5th

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

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

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

Incoming rain

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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.

There are tiny acorns on the Oaks; stalked ones on the Pedunculate Oaks and tight-to-the-twig ones on the Sessile Oaks.

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.

Downland slope

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.

23/6/16-Pyramidal Orchid-Bryn Euryn

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.

June 23rd- Bryn Euryn

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.

23/6/16-Pellucid fly-Volucella pellucens on bramble flower

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!

Syrphus sp hoverfly in a Dog Rose

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 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.

A Carder bumblebee in action on red and then white clover:

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.

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.

And to finish, a female Common Blue.

Foxglove-Digitalis

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.

Wild Strawberry

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.

A Blackbird male paused from singing to hunt on the woodland track

False Brome-Brachypodium sylvaticum

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.

Oak leaves are already being eaten

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.

A variety of meadow grasses with Common rockrose and 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.

Burnet rose with Tree bumblebee

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.

Burnet roses with Rust fungus

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

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.

Summit Trail

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 from a distance

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!

Dingy Skipper-Erynnis tages

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.

Dingy Skipper underside

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. For more about the Dingy Skipper, go to http://butterfly-conservation.org/679-1101/dingy-skipper.html

Fairy Moths & Sainted Flies

Adela reaumurella, bibio marci, black fly with long dangling legs, fairy long-horn moth, green long-horn moth, St Mark's fly, swarm of black flies in Spring

I first saw the delightfully strange little Green Longhorn moths on Bryn Euryn on the 13th May last year, where a fairly large number of them were dancing around an oak tree in the sunshine. Initially I thought they may be St Mark’s flies, but as I got closer I could see these insects were much tinier, had ridiculously long white antennae and wings that had a metallic greeny-bronze sheen to them. It took me a while after that to discover their identity, but finally learnt that they were Long-horn moths, also known as Fairy Long-horn moths and this particular species was the Green Long-horn moth, Adela reaumurella.

Finding them in the exact same location yesterday (May 9th), was a surprise and a treat, more so as this time they were mixed in with a largish number of St Mark’s flies and were behaving differently. No group dancing today, the combined species, all male, were travelling along rather erratically in a wide ribbon, staying within the cover of the oak leaves and making frequent individual brief stops on leaves. They were maintaining a consistent height above the ground at about my head height (I’m 5′ 3″), and progressing along the band of trees and shrubs that border one side of the meadow. I’d love to know what was happening.

GREEN (FAIRY) LONG-HORN MOTH-Adela reaumurella

DESCRIPTION

Wingspan: 14-18mm; both sexes have rough black hair on their heads and thorax, giving them a furry appearance when seen close-up. Upperwings are a metallic green-bronze and underwings are metallic bronze. Males have extremely long, whitish antennae; the females’ antennae are shorter.

HABITAT

Open areas such as heathland, moorland, country gardens, parks and wherever the larval foodplant is found.

The moths fly in the daytime during May and June, sometimes occurring in swarms and often around the tops of trees and bushes.

LIFE HISTORY

The larvae feed on leaf litter of Oak and Birch and make themselves portable cases with leaf fragments. The larvae have no prolegs and pupate in their larval cases.

ST MARK’S FLY – Bibio marci

The St. Mark’s Fly is a species of true fly, also known as Hawthorn flies and belongs to the family Bibionidae.

This jet-black fly is so-named as it frequently appears on or around the feast day of St Mark, which falls on April 25th and is seen in flight in May. They are found around woodland edges, hedges, rough grassland and wetlands and can be seen throughout the UK in spring. The males are often encountered in a swarm drifting slowly up and down at about a person’s head height, long legs dangling, trying to attract females. The swarms can be annoying, especially if you have to walk through one, and the insects are not averse to landing on people. However, they are harmless and as insects that feed on nectar, they are important pollinators, particularly of fruit trees and crops.

DESCRIPTION

Length: The male is about 12 mm and the female 14 mm long. Although appearing black and shiny, this is quite a hairy black insect. Wings: The wings have a black front edge. The compound eyes are large and bulbous and they have a rather tubular segmented body and black legs. The front legs have a stout spine at the tip of the tibia.

The females are larger, have smoky wings and much a smaller head and eyes.

LIFE HISTORY

The St. Mark’s Fly has a very short adult life cycle, being in flight for approximately only one week. The majority of their time is spent as larva in the soil. During autumn and winter, larvae feed on rotting vegetation which they chew with their strong mouthparts. In springtime the males emerge first and the females a few days later. After mating, females lay their eggs in the soil and die soon afterwards.

Welcome back to the Mistle Thrush

At 7.10 am it was barely light, but from high in a cherry tree, easily piercing the double glazing of my living room window, a Mistle thrush exuberantly proclaimed his return. He sang long and loud for at least the next hour before crossing the building to announce his presence from the woodland edge behind us. I was out for most of the day, but arriving home at 5 pm, again in the fading light, he was back in the same place reinforcing his presence.

I could barely see him, so much to dark to photograph him, so the photograph is one from last year that I took of a bird in the neighbouring tree that arrived here on a similar date and behaved in a very similar way. I would like to believe it was the same bird returning to reclaim his breeding territory, especially as the Mistle thrush has moved from the amber list to red-listed status as a bird of conservation concern, with 170,000 breeding territories recorded.

Mistle thrushes are early nesters and many nests are built in late February. typically they favour sites in woodland as high as 30ft up on the top of a snapped-off tree. Each pair raises two or occasionally three broods and they may sometimes use the same nest. To my knowledge at least one pair bred successfully here on Bryn Euryn last year and similarly the previous year, so this is clearly a well-established breeding site – fingers crossed for this year too.

Wildflowers in Winter

Daisies look delicate, but they’re tough little plants and flower more-or-less continuously from December to January. I love them so am happy they can decorate grassy areas in peace before the lawn-mowers emerge from hibernation.

Daisy-Bellis perennis

Celandines are one of the first heralds of Spring, but I was taken by surprise to find some this early in the year.

Lesser Celandine-Ficaria verna

Herb Robert was also a surprise, its flowering season is more April-November, so this is probably a plant that has not died down and carried on growing.

Another survivor is this Nipplewort which is growing in a sheltered corner against a wall on the roadside.

There are some wildflowers that are truly winter flowering. The bright green leaves of Winter heliotrope are present here throughout the year and the lilac flowers, which have a fragrant, vanilla-like scent appear from November to March.

January 26th was a mild sunny day, warm enough to coax out this little Red-tailed bumblebee, but it seemed to be struggling to take off from the flower, so maybe it wasn’t quite warm enough.

Three-cornered Garlic is named for the shape of its flower stems, which are triangular. It is also known as White bluebell and does resemble one, until you smell it. It’s flowering season is February- June but has been in flower here since last December.

“When gorse is out of bloom, kissing is out of season“. In other words, gorse pretty much flowers all year round to some extent. Now, at the end of this mild January many bushes are well-covered with the lusciously coconut-scented blossom.

Gorse

Hazel catkins have also been present on some trees since last month.

Sycamore buds are greening

A few trees have retained their dried leaves for some reason, this is a small oak.

Some plants characteristically hang on to their berries well into the winter, one such is the unfortunately-named Stinking iris that has bright orange berries

and another is Black bryony, whose bright scarlet berries garland shrubs like strings of shiny beads.

A surprising number of ferns are still green

Both the Male fern and the Hart’s Tongue fern are semi-evergreen, but this group shows no sign of dying down at all.

Winter is a good time to appreciate mosses. Looking closely at this one it has fern-like leaves.

On a fallen Scots pine a colony of tiny bright yellow coloured fungi has established itself; it seems to be a bracket fungi, maybe a turkeytail?

Autumn in North Wales is glorious this year thanks to a prolonged sunny and mild spell of weather, as yet broken only occasionally by rain. Walking between the trees in the dappled shade of the woodland along sun-striped paths thickly carpeted with fallen leaves in all the shades of the season, has been truly joyful. As October draws to an end, here are some of my views of the month.

Ivy is flowering now providing vital supplies of pollen and nectar to late-flying insects.

Ash trees leaves have mostly turned to a bright yellow.

Many have already fallen.

Oak trees are in varying shades, some still retaining a lot of green where they are in shade while those exposed to more sunlight have turned golden.

Last year there was a national shortage of acorns and here at least it doesn’t look as though this year is going to be any more productive.

In a sunny spot I watched a gathering of a dozen or so hoverflies. Some were hovering and darting around, others were attempting to bask in the sunshine but were deliberately disturbed by their dive-bombing peers.
