Beauty is where you find it and often in the least likely of places, but in nature it may also be fleeting, so needs to be appreciated when the opportunity presents itself. Here are a few images of some things I found beautiful along the way of a short walk I made from home into Rhos-on-Sea village on a windy, sunny-ish morning last week. Some would most definitely not be there if I were to look for them again.

I had set off to see if there was anything interesting to see down on the seashore and walked along the promenade to reach a point from which to access it. The promenade is on a lower level to the road and pavement for a short stretch here and the intervening space between the two is a steep slope covered with grass. This grassy embankment is mowed every now and then, but the times between cuts are often long enough to allow opportunistic weed wildflowers to pop up and bloom and in different seasons I have spotted a good variety of species here.

Reaching the top of the path leading down to the prom I heard first, then saw a man on a sit-on mower working on the flatter grass verge going in the opposite direction towards Penrhyn Bay. This prompted me to get a move on and have a look to see what might be flowering lower down as it clearly would not be there for much longer.

First to catch my eye was a tangle of white-flowered bindweed. Generally similar to the large flowered bindweed that abounds in waste places and on road verges, as well as being the bane of many a gardener’s life, this was the smaller-flowered Hedge Bindweed.

Flowers are smaller than those of Large Bindweed

Lower down in the grass there was Creeping Cinquefoil, some of the golden yellow flowers fading around the edges.

Small flowers attract small insects

There were insects nectaring on most of the available flowers, including bumblebees, hoverflies and various other flies.

I hope they all escaped the blades of the mower that was about two minutes behind me as I took these photographs. I’m glad I got there when I did, otherwise I would not have seen the flowers at all.

The tide was turning and beginning its journey back into the shore and although I could see and hear a lot of birds out on the tide-line, including curlew, redshank & oystercatcher, they were way too far away to see properly.

With or without the added interest of birds though, I can meander contentedly along this rocky seashore at any time, finding the rocks themselves endlessly fascinating.

Perhaps the rounded shapes on this rock were made by molluscs attached to it

We don’t get much variety in the seashells on the shore here, although not surprisingly there are an awful lot of mussel shells.

I spent a few minutes watching a cluster of Kelp Flies, appropriately on a length of brown, leathery Kelp seaweed.These are the insects that fly up if you walk through or even past clumps of dryish seaweed. They are quite tiny, so I thought it might be interesting to have a closer look at one. Not beautiful maybe, unless you are another Kelp Fly, but the wings are nice and they have dainty white feet.

Kelp Fly – Coelopa frigida

So I travelled slowly along and eventually arrived at the sandy beach area next to the small harbour area of the village. The beach is protected by a barrage of more large rocks that has to be surmounted to reach it and as I clambered over them I spotted a colourful splash of flowering plants growing at the back of the building that is now a fishing-tackle shop and kayaking centre. This is not a particularly attractive spot and any wind-blown rubbish from the beach tends to get caught up here, but I have come across some interesting plants here, so is always worth a closer look at.

What had caught my eye today was a large clump of Common Mallow that had found shelter in a corner tight against a wall and was clearly thriving there.

Another common plant in waste places, especially on sandy soils is Annual Wall-Rocket and there are usually a few of these plants growing around this location.

There was a large plant of Fat-hen too, and another one right on the edge of the sand just a short way from the sea.

Amongst the commoner plants I was pleased to find this Ray’s Knotgrass, an annual plant that is most often found on undisturbed coastal sand and shingle beaches.

There was Sea Plantain, whose flowers are almost over now.

Then the prettiest of them all, the lovely Sea Mayweed.

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.

Some days the intention of a walk is at the forefront of my mind, then ‘stuff’ crops up and before I know it the day is almost over and the momentum needed to get me out of the door is fading fast. This was almost one of those days, when at six thirty-something I was still preoccupied with getting things done in the house. Luckily I finally acknowledged the little nagging voice in the back of my mind that was insisting I got out for some fresh air. I almost ignored it, then gave in, grabbed my camera, put on walking shoes and headed out with no real idea where I was heading for.

At around seven I arrived at the Little Orme. I knew before I arrived that by this time in the evening most of the area on this most accessible side of the headland would be in the shadow of its bulk, as the late sun slips down and slides around it to set just about behind its tip. There were quite a few people about too; dog walkers of course, some holidaymakers dressed up for the evening, maybe taking an evening constitutional before dinner & a couple of groups of teenagers, one lot jumping, diving, shouting and laughing from a rocky ledge into the sea. I quickly judged that this was not a scenario I would normally enter into if hoping to spot any wildlife and on that basis decided this outing would be for the purpose of exercise. So a brisk walk to the cliff edge, an about turn and a concerted effort to get to the top of Rabbit Hill with minimum stops to catch breath, back down again and home ought to do it.

A group of people with two dogs was heading toward me, so to avoid them momentarily I stepped off the main path onto a narrow track that leads around the cliff, skirting what is currently a large patch of long grass. It took less than a minute of being there to spot that a good number of Meadow Brown butterflies were flitting about amongst the grass stems and settling there. It took slightly longer to realise they were there to roost for the night.

I tried to approach several butterflies, treading slowly and carefully through the grass, but I couldn’t get close enough to them to photograph and hadn’t picked up my more powerful zoom lens when I left the house as I didn’t expect to need it. I continued to try until following one individual led me to discover a cluster of Six-spot Burnet Moths on a single grass-head.

It was clear that the Moths were in differing conditions, with one n particular looking a bit battered and with most of the colour gone from its wings. I assumed that as with the Meadow Browns the Burnets were also seeking to roost for the night and turned my attention to a passing Small Skipper that settled obligingly on another nearby grass-head.

Small Skipper- Thymelicus sylvestris

I was happy now, especially as in the cool of the evening the butterflies and moths were not as mobile as they are during the day and were allowing me to get quite close to them with the camera.

Another Small Skipper

As I moved through the grass and further towards the cliff edge I began seeing more Burnet moths. And more.

It slowly dawned upon me that although the butterflies were roosting, the moths were not. They were out intent on mating.

I could hardly believe the numbers of moths that were gathered here in this relatively small area of long grass. I have been to visit this reserve many times and felt lucky to see half a dozen individuals on a sunny afternoon, now I was surrounded by them. They were literally everywhere I looked. It still took a further while though to realise that even more amazingly, I had arrived at exactly the time the new moths were almost simultaneously emerging from their cocoons.

6-spot Burnet Moth emerging from its pupa

I had begun to spot the yellow cocoons with something black and alien-looking emerging from them, but couldn’t quite imagine it ending up as a moth at all, so at first thought they were something else. I don’t what, just something else.

A closer view of an emerging moth still doesn’t look like one

It was only when I spotted other Burnet moths perched on top of cocoons from which another was emerging that I was convinced that somehow these crumpled black forms would indeed eventually look just like them.

I began to wonder then why the moths were sitting on top of the pupae. I’m afraid the only theory I could come up with was that they were male moths staking a claim on emerging females to mate with them as soon as they became viable. Not pretty, but probably not far off the mark. (more about 6-spot Burnet Moth)

I tried watching an emergence for a while, but it seemed like a lengthy process, so still marvelling at my luck in witnessing this epic event, I left the moths to their nuptials and moved on. I would have been happy to have taken my previously outlined walk now and returned home, but it turned out there were still a few things to see in the gathering dusk.

Ragwort is in full vibrant bloom now and I just had to look for black and yellow striped caterpillars of the Cinnabar moth. I was not disappointed, there were plenty in sizes varying from very tiny to very large.

I was also fortunate to spot a prettily marked moth : this is an Antler moth, so called because of the distinctive antler-shaped markings on its forewings. One of the species that flies in daylight.

On the cliff above Angel Bay is another patch of long grass, but here it is mixed with wildflowers such as hogweed, ragwort and a sprinkling of knapweed, all important nectar plants for insects. This evening there were still a few to be found out dining including bumblebees and one little Sulphur beetle.

Sulphur beetle- Cteniopus sulphureus

I left for home happily and exercised – I made it up to the top of Rabbit Hill, admittedly pausing a couple of times, but why wouldn’t you when the view is so spectacular and the sun is setting so beautifully over the sea?

The strangely beautiful Carline Thistle

Carline thistle plant growing amongst rocks on Bryn Euryn

The Carline thistle is one of a handful of more unusual plants occurring in several of our nature reserves that have areas of dry calcareous grassland. It is a biennial plant so its appearance can be rather unpredictable both in exact location and in numbers of individual plants; it is never what you could call abundant. The plant can be seen throughout most of the year as when it’s finished flowering it persists as a very dry skeletal form of itself.

In past years I have found them on both ‘Ormes’, Little and Great but the best specimens, this year at least, are to be found growing on the top, rocky areas of Bryn Euryn.

Carline Thistle

Carlina vulgaris

Family: Daisy & Dandelion Asteraceae; biennial to 80cm; flowering June to September

The Common Carline Thistle is a short, stout and prickly little thistle with intriguing golden-brown-tinged-purple, rayless flowers (15-40mm across) that are surrounded by conspicuous, spiny, sepal-like yellow bracts which spread widely apart beneath. In the bright sunshine, they glisten silver and gold and in wet weather they close up.

The flowerheads are carried on densely prickly, leafy stems. The oblong leaves have toothed or lobed blades with spiny edges.

In bud the flower is contained by a tight mass of dark purplish brown or black spines intertwined with a net of white fibres resembling cotton wool.

At first, the opening heads look rather like dead or dying daisies, but this is their normal appearance.

The inner florets are straw yellow at first, but then purple petals start to emerge from the periphery, gradually proceeding towards the centre.

The dead flower, after the season is over, appears much as it did when it was alive.

Traditional uses

The flower head was once used as a humidity gauge because the bracts close in the higher humidity typical of impending rain.

This plant had some uses in folk medicine and legend has it that it got its common name ‘Carline’ because the Emperor Charlemagne used the plant to cure his army of pestilence.

Subsequently it has been discovered that both Stemless Carline Thistle(Carlina aucalis) (where it was first found) and Carline Thistle contain the acetylide Carlina Oxide orCarlinoxide (furylbenzylacetylene), the main compound (85% – 90%) of the essential oil from the plant, which has a long history of medicinal use in Europe due to its anti-microbial properties. It is active against two strains of MRSA and a number of other difficult infections. It is stomachic, carminative, diaphoretic and an antibiotic.
