Part 3 – Rhiwleddyn Nature Reserve

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

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

Common Sorrel Rumex acetosa

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

Great Mullein – Verbascum thrapsis

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

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

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

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

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

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

Brown Argus Aricia argestis

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

Banded burdock fly-Terellia tussilaginis

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

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

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

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

Limping pheasant

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

Spiked Speedwell-Veronica spicata

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

Dropwort – Filipendula vulgaris

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

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

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

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

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

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

First week

The weather up here in our part of North Wales has been variable this week. We have had a good bit of rain which has freshened everywhere up and just about enough warm sunshine to allow us to keep the faith that this is indeed high summer. It may not be the perfect weather for people here on holiday, but the local wildflowers and insects seem to be appreciating it.

Habitat: Long meadow grass

There is a whole other world existing in areas where grass is allowed to grow long and during the past couple of weeks I’ve begun to appreciate its importance as a home and a refuge for wildlife, particularly insects and spiders.

All journeys need a starting point and the following journey of discovery into the dimension of long grass began when I went to Bryn Euryn to see if a particular plant was in flower.

I’ve mentioned before that we have a few less-usual species of wildflowers growing in our locality and on Bryn Euryn this is the time to find one of them; the pink/purple flowered Keeled Garlic. I headed for the spot I had seen it in previous years and there it was, buzzing with bumblebees and more surprisingly attracting several beautiful little Common Blue butterflies.

Keeled Garlic

I wondered at the attraction of this particular flower to the butterflies and thought perhaps they were just resting on the tiny flowers to sunbathe. A little later though I came upon another patch of the flowers with more Common Blues fluttering over and settling upon it, so maybe they were taking nectar from them. I was more than happy to see this many of the butterflies in the same place at the same time; I haven’t seen that for a long time.

I was not the only one to recognise the attraction of insects to the garlic flowers. Lurking on top of her tent-like web, built to protect her eggs and then babies, sat a long-legged Nursery Web spider.

Nursery Web spider-

Nursery Web spiders are the spinners of the many web ‘tents’ seen in grassy places at this time of year. They take their common name from the way in which they care for their offspring. The female carries her large egg sac beneath her body, held in her jaws. Before the eggs hatch she spins the silken tent around the egg sac and stands guard over them. She remains on duty until the spiderlings are big enough to live independently. The spiders are active hunters and search for prey amongst grasses and low vegetation.

A neighbour

Walking carefully through the long grass, every step seems to disturb a dry-grass coloured moth. They are so well camouflaged that should you manage to keep track of where they land, it’s not easy to find them again; then if you manage a picture of sorts identifying them afterwards is even harder. The one below, which landed on the pupa of a 6-Spot Burnet moth which I would otherwise not have spotted, maybe Crambus pascuella (?) As always, I’m more than happy to be corrected.

This one landed on the pupa of a 6-spot Burnet Moth

In places amongst the grass knapweed is beginning to open up it tight dark knots of buds to allow the purple brush-head of petals to escape. Knapweed is a hugely important source of nectar for a wide variety of insects, but more about the plant and its visitors later.

Knapweed in long grass

Long grass on dry slope of ‘downland’

The area of long grass at the bottom of the summit slope on the drier, chalkier downland side of the Bryn has a different character to the flatter, damper meadow area. Some species of butterfly you may see here, although found in other parts of the Reserve, show a definite preference for the conditions it offers and may be more numerous. It is especially good for seeing the smaller species that gain protection from predators amongst the grass stems and include Small Heath, Small Skipper, Common Blue and the less-common Brown Argus.

The larval host plant of the Brown Argus is Rock Rose, which has been prolific in its flowering here this year and the leaves of the plants are still evident in the ‘under-story’ of this grassy forest. I was once again lucky with the timing of my visit this week; after a few minutes of pursuing little butterflies through the tangle of dry grass laced across with long outreaching bramble runners, I spotted a newly emerged Brown Argus balanced on top of a dry stem.

5/8/14 – Brown Argus- Aricia agestis

It stayed perfectly still, wings outstretched for quite a long time and made no attempt to fly off although I was very close and holding the camera lens just a few inches from it. I was almost certain this was in fact a Brown Argus and not a female Common Blue, but was compelled to wait and hope it would close its wings for me to see its underside. It eventually obliged and although the angle it presented wasn’t the best, thankfully it did confirm its identity with its diagnostic pattern of spots.

Spot the difference:

Text & diagram from the UK Butterflies web site demonstrates the differences:

Of the two sexes, it is the female Common Blue that causes most confusion with the Brown Argus. The blue present in a female Common Blue is highly variable, with individuals ranging from almost completely blue through to completely brown. It is this latter colouring that causes the most confusion. Even so, the Brown Argus has no blue scales, but may give off a blue sheen from the wings and the hairs found on the thorax and abdomen. Another diagnostic is that the Brown Argus normally has a prominent dark spot in the centre of the forewings.

The North Wales Wildlife Trust reserve at Bryn Pydew is becoming one of my new favourite places to visit, especially to see some of our less-common wildflowers and a variety of insects.

The first thing to attract my attention today was a Small Heath butterfly. Fluttering along low to the ground it kept disappearing from my sight as it landed amongst the stems of long grass, but I managed to follow it along the woodland edge for a short way until I was distracted by the corpse of a little shrew. It didn’t appear to have been there for long, but there were puncture wounds around its back so had clearly been caught by something with sharp teeth and the fact that it had not been eaten suggests a domestic cat; they don’t like the taste of shrew and often leave their victims lying at the side of paths etc.

Common Shrew – Sorex araneus Welsh: Llyg Cyffredin

British shrews are protected by the Wildlife and Countryside Act 1981, and it is an offence to kill them without a special licence.

Description: As with all shrews, the common shrew has a long, flexible snout, small eyes and tiny ears. They have dark brown fur on their backs, paler sides and an even paler underside. Their heads are not as domed in shape as that of the even smaller pygmy shrew and the tail is proportionately shorter than that of the smaller species.

Food: All shrews have voracious appetites; they need to feed every 2-3 hours and consume up to 90% of their body weight in any 24 hour period. They eat most terrestrial insects, but also take worms, slugs and snails; they have a good sense of smell and feeling, but they do not dig for their prey.They lack the fat reserves to see them though the winter so do not hibernate and can be seen all year round. Apart from those killed by cats, shrew corpses may also be those of animals that have not been able to find enough food.

Behaviour: They are solitary, territorial animals and often fight when they come into contact with their neighbours. The high pitched squeaking sound that they make can often be heard as you walk along footpaths; they are most active at night and during dawn and dusk and intersperse periods of intense activity with resting.

Reproduction

Shrews build nests below the ground or under dense vegetation. After a gestation period of 22-25 days, females give birth to 4-7 young, which are weaned after 22 days. They breed from April to October, with a peak in the summer.

_______________________________________________________

I lost the butterfly but was soon compensated with a lovely bright metallic green beetle rummaging around in the stamens of a Welsh poppy.

Oedemera nobilis feeding on pollen

This was the first, rather hasty photograph I took of the handsome beetle and followed it with a number of what I thought would be much better shots, but when I downloaded the day’s bounty I discovered all of them were unreadable, so goodness knows what happened there. Hopefully I will find more another day.

Dog Rose- Rosa canina

The open patch of ground just inside the site boundary is lovely now, lush with a mix of tall meadow grasses swaying gently in the day’s light breeze and catching the sunlight. Dog rose shrubs are in glorious full bloom.

In a sunny patch of shorter turf where there was Red Clover and Bird’s-foot Trefoil growing I stopped to watch Common Blue and Brown Argus butterflies and bumblebees. Both species of butterfly are territorial despite their tiny size and were chasing off anything and everything that dared enter their airspace.

There’s not much to see in the woodland here, the trees, including a good number of yews grow closely together, shutting out much of the sunlight, so it is very dark and quiet in there. I did spot a young Wren demanding attention from a parent though, calling loudly and flapping its wings wildly to try to maintain its balance on a fence post. It is only a short downhill walk to take before reaching the open area of Limestone Pavement. It’s a little more overgrown now than the last time I saw it, with quite a few tree saplings and brambles getting a foothold. I know little or nothing about how you would go about maintaining a limestone pavement though, so have no idea what would be removed, or when, but there are some lovely wildflowers here currently and it would be a shame if they were smothered by brambles.

The main expanse of Limestone Pavement

Common Rockrose

There is quite a bit of rockrose, interspersed with salad burnet with its curious flowerheads.

Salad Burnet– Sanguisorba minor is a low-growing herb of chalk and limestone grasslands which produces rounded, reddish flower heads from May to September. The leaves of Salad Burnet comprise up to 12 pairs of rounded, toothed leaflets, and form a rosette at the base of the flower stem. The rounded flower heads are reddish and speckled.

The leaves are famous for smelling of cucumber if crushed or walked upon, and this plant lives up to its name as a popular addition to salads and summer drinks.

I try not to plan my outings too much, preferring to take things as they come at the time, but I was hoping to find one of this site’s ‘special’ plants in flower today. Dropwort-filipendula vulgaris is a clumsy (pardon the pun) name for a very elegant and rather ‘frothy’ plant. I found a couple of stems at the end of their flowering late last summer, but hoped to find more today. I was pleased then to find the first ones, which I recognised by the pretty fern-like leaves, but alas the flowers were still tightly budded. Once I had spotted one I found more, but all were tightly closed.

Dropwort in bud

Again there was compensation for not finding what I was hoping for; this time it was Bloody Cranesbill –Geranium Sanguinem, which is not at all a common plant and in Wales restricted to a few limestone-rich coastal areas. It grows also on the Great Orme, a few miles away in Llandudno and I have also seen it on Llanddwyn Island in Anglesey.

There are many colour variations of this plant species, but it takes the ‘Bloody’ part of its name from the blood-red sepals that remain after the petals have fallen.

Broad-leaved Willowherb, one of the more ‘ordinary’ wildflowers to be found here

Wood Avens

Leaving this main area of the limestone pavement and continuing downhill through a narrow belt of woodland you emerge into an open grassy area that is so pretty I was half-expecting Bambi and friends to pop out. There were a few Purple Spotted Orchids here, very nearly finished, an impressive group of Bloody Cranesbill and more Rockroses.

At the far end of this small woodland glade is another smaller section of pavement, which is where I found the Dropwort last year. There was no sign of the plant in the exact same place, but I did spot a couple of little pale pink orchids. Once again, as I got my eye in, I found more of them, most not quite fully out yet.

Heath-spotted Orchid- Dactylorhiza maculata

I sat in the sunshine on the edge of the rocky pavement for a while, admiring the view across to Penrhyn Bay and watching more Small Heath butterflies fluttering over the stony ground where they settled to bask occasionally. I realised then that the reason I was finding it difficult to spot them earlier was because they settle very low to the ground, almost horizontal to it. As I got up to leave one fluttered along the grass in front of me, settling some metres ahead, so I took a series of photographs as I inched towards it, each one a little closer. It allowed me to get very close before flying off from here.

Small Heath – Coenonympha pamphilus

Quite unexpectedly then, just a short distance away from the butterfly I glanced up to see the flower I was hoping for in peachy pink and creamy white frothy glory. A Dropwort in almost full glorious bloom. What a treat.

Dropwort in full peaches and cream frothy glory

Dropwort (Filipendula vulgaris), also known as Fern-leaf Dropwort, is a perennial herb of the family Rosaceae and closely related to Meadowsweet. It is found in dry pastures across much of Europe and central and northern Asia, preferring full sun to partial shade and is more tolerant of dry conditions than most other members of its genus.

It has finely-cut, radical leaves, fern-like in appearance, and an erect stem 20–50 centimetres (8–20 in) tall. The tiny creamy white flowers appear in dense clusters from late spring to mid summer. The crushed leaves and roots have a scent of oil of wintergreen (Methyl salicylate).
