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

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

August 5th

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

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

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

Incoming rain

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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.

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

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.

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.

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.

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.

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!

160605-BE1256-Nottingham Catchfly (5)

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

160605-BE1256-Nottingham Catchfly (4)

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

160605-BE1256-Nottingham Catchfly (3)

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

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

160605-BE1256-Nottingham Catchfly (2)

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

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

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

Variable summer weather is perhaps more the norm here in North Wales than in some other parts of the UK, although we still feel hard done to when yet another day dawns doomed to be overcast. There are many compensations though, one of which is that when the odd sunny, or partially sunny day occurs, the insects come out in force in search of sustenance. I photographed all of the following along Bryn Euryn’s Woodland Trail during a fleeting sunny spell a couple of weeks ago.

On the edge of the trail a substantial bramble was still flowering and literally buzzing with insects, mostly hoverflies and bees. There were two butterflies, a Red Admiral and a Comma that were flying around rather frantically, both of which briefly (and separately) landed on my arm. Poor things were clearly overcome by the presence of both sun and nectar. I would have liked a more conventional shot of the Comma, this being the first I’d seen here this year, but it was taunting me from high over my head so this was my best view. I rather like it and it’s clear from the outline that it is a Comma.

The hoverflies were very active, not pausing for long but these are the ones I could get to fairly easily:

A less charming insect to many, I find the Flesh-eating fly-Sarcophaga carnaria rather attractive to look at. I think the white feet complete the look, makes it look rather dapper.

The trees are still green and fresh-looking thanks to the rain and cooler weather, although those in the top right of the next picture are looking quite lacy.

Continuing along the trail I hear a few birds letting the world know they are still about, Chiffchaff song bursts were fairly frequent, I heard Wrens and the contact calls of Blue Tits and plenty of corvid cawings. I found this feather too, maybe once belonging to a Magpie, it gleamed shades of almost peacock-blue in the dappled sunlight.

A rather unusual plant grows here in the shady woodland, delightfully named the Stinking Iris and sometimes the ‘Roast-beef Plant’, both names allude to the sweetly acrid smell, like ‘high’ meat. This is one of just two Iris species native to the UK; the other is the Yellow Flag Iris.

Are bees ‘hooked’ on nectar containing pesticides? — ScienceDaily

12 Sunday Jul 2015

Posted by theresagreen in bumblebees, Nature of Wales

≈ 2 Comments

I found this article really interesting and thought I’d share it.

Bees are attracted to nectar containing common pesticides, scientists at Newcastle University and Trinity College Dublin have discovered. This could increase their chances of exposure to high levels of pesticides.

Previous studies have suggested that exposure of this kind can affect bees’ fitness. The research, published in Nature, discovered that buff-tailed bumblebees and honeybees could not taste the three most commonly used neonicotinoid pesticides and so did not avoid them. In fact, the bees showed a preference for food which contained pesticides: when the bees were given a choice between sugar solution, and sugar solution containing neonicotinoids, they chose the neonicotinoid-laced food.

The lab-based study also showed that the bumblebees ate more of the food containing pesticides than the honeybees, and so were exposed to higher doses of toxins.

Bees and other pollinating insects are important for increasing crop yields — their value has been estimated to be worth at least €153billion per year globally. When pollinating crops, they can be exposed to pesticides in floral nectar and pollen. Several controversial studies have shown that neonicotinoids have negative effects on bee foraging and colony fitness. As a result, public concern has grown over the impact of neonicotinoids on bees and other pollinators. In April 2013, the EU introduced a temporary ban on the use of neonicotinoid pesticides on flowering crops, while further scientific and technical evidence was gathered.

Professor Geraldine Wright, lead scientist on the study at the Institute of Neuroscience at Newcastle University, said: “Bees can’t taste neonicotinoids in their food and therefore do not avoid these pesticides. This is putting them at risk of poisoning when they eat contaminated nectar.

“Even worse, we now have evidence that bees prefer to eat pesticide-contaminated food. Neonicotinoids target the same mechanisms in the bee brain that are affected by nicotine in the human brain. The fact that bees show a preference for food containing neonicotinoids is concerning as it suggests that like nicotine, neonicotinoids may act like a drug to make foods containing these substances more rewarding. “If foraging bees prefer to collect nectar containing neonicotinoids, this could have a knock-on negative impact on whole colonies and on bee populations.”

Jane Stout, Professor of Botany and Principal Investigator in the School of Natural Sciences at Trinity College Dublin, said: “Our findings imply that even if alternative food sources are provided for bees in agricultural landscapes where neonicotinoid pesticides are used, the bees may prefer to forage on the neonicotinoid-contaminated crops. Since neonicotinoids can also end up in wild plants growing adjacent to crops, they could be much more prevalent in bees’ diets than previously thought.”

The study is part of the Insect Pollinators Initiative, jointly funded by the Biotechnology and Biological Sciences Research Council (BBSRC), Defra, the Natural Environment Research Council (NERC), the Scottish Government and the Wellcome Trust under the auspices of the Living with Environmental Change (LWEC) partnership. It was also funded by Science Foundation Ireland, the Irish Research Council, and National Science Foundation.

Bumbles, Masons and Miners

Early spring is a good time to look out for some of the different species of bees found locally, catching them before they settle in to producing the next generation. On recent outings Bryn Euryn was particularly well blessed with bumblebees and some other interesting species and the Little Orme brought an unexpected treat so I thought I’d put them all together.

The Buff-tailed bumblebee- Bombus terrestris is the largest of our native bumblebees. Queens, workers and males have a dirty golden yellow collar near the head and one on the abdomen.

Buff-tailed bumblebee

Bryn Euryn – Buff-tailed bumblebee queen

The queen’s tail is an off white/buff colour which can sometimes appear orange. The queens are busy establishing new colonies and may be seen collecting pollen to stock it and crawling around on the ground where they nest in burrows underground.

Buff-tailed bumblebee queen on the ground

Bryn Euryn-Buff-tailed bumblebee queen on the ground

I didn’t spot any workers or males on the days I was out and about, if I had these would both be smaller than the queens and look slightly different as workers have a white tail and that of the males is white ringed with a buff line.

Red-tailed Bumblebee- Bombus lapidarius queens are also establishing new colonies and can be seen feeding and collecting pollen from flowers and also crawling around on the ground as they too nest underground.

Queens are distinctive with their black bodies and red tails and are large, between 20 -22mm long which is a similar length to that of the Buff-tailed bumblebee queens, but the red-tailed is less bulky.

There are Red-tailed bumblebee workers about too. They have the same colouring as the queens but are smaller, varying in size from 1-16mm in length, with some early workers being no bigger than a house fly.

They have comparatively short tongues and favour flowers that provide them with a landing platform such as dandelions and daisies and later on, thistles and ragwort. In gardens they like chive flowers and lavender.

To make things confusing there is a cuckoo-bee that closely resembles the Red-tailed bumblebee. The main differences are that the cuckoo bee has black wings and the back legs are hairy and without the shiny hairless patch, the pollen basket, of the true bee.

There were a very few Common Carder bees Bombus pascuorum about and I only managed one quick shot of one visiting a dog violet flower. There will be many more later on.

An exciting new recording for me here was of the Tree Bumblebee Bombus hypnorum, that’s is not to say they weren’t here before, just that I had never seen one. I was lucky to spot two that were taking nectar from the Green Alkanet flowers which grow in a big patch next to the car-park gate.

21/4/15 – Bryn Euryn-Tree bumblebee-Bombus hypnorum

Tree bumblebees are fairly new arrivals to the UK, first found in 2001 in Wiltshire. Since then they have spread across most of England and Wales and made it to Southern Scotland in 2013. Queens, workers and males all have a similar colour pattern; the thorax is tawny to reddish-brown, the abdomen is black and the tail is white.

Queens vary significantly in size and can reach up to 18mm in length. Males are quite chunky and can be as much as 16mm in length; fresh males have a patch of yellowish facial hair which eventually wears off. Workers, which is what I believe I photographed range from 11-16mm in length; they move around rapidly and are effective pollinators.

Basking on the leaves of the butterbur plant that also grows near the gate at the bottom end of of the car park was another little bee. I’m not positive about its identification but based on the colour of the hairs on its thorax I think it may be an Early Mining Bee – Andrena haemorrhoa.

A couple of days later I was walking on the Little Orme and came across another species of mining bee that cannot be mistaken for anything else, the Tawny Mining Bee-Andrena fulva.

There were two individuals attempting to nectar on Alexander’s while a particularly strong wind was bending and tossing the flower around. It was tricky trying to get focussed images.

Males are 10 to 12 mm and the females 8 to 10 mm long. The females are covered with fox red hair on their backs and black on the underside, whilst the males are more slender and yellower in appearance.

One of the two managed to hold on and kept searching over the florets, but the other gave up and dropped to the ground.

The bees mate in spring, after which the male dies and the female starts to build a nest. Sometimes more than a hundred females build nests in a few square metres but the Tawny Mining Bee normally does not create a colony: each female has her own nest.

Finally I’d like to mention another little bee found locally, the Red Mason Bee Osmia rufa, also most likely to be spotted around this time of year.

Fairy Glen-Red Mason Bee

The males are smaller than the females at 6 -11 mm. Both sexes are covered in dense gingery hairs, the male with white tufts on the head while the female’s head is black.

It is a solitary bee, each nest being the work of a single female bee working alone. They nest in pre-existing cavities such as hollow plant stems, old garden canes, air bricks, and even old nail holes in fence posts, lining the inside of the cavity with mud.

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

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 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.

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

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.

Brown Argus-

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.

Burnet Rose- Rosa pimpinellifolia

28 Wednesday May 2014

burnet rose, low-growing white rose, Phragmidium rosa-pimpinellifoliae, rosa pimpinellifolia

Family: Rosaceae Other English name: Pimpinell Rose Welsh name: Rhosyn Dewi (Rhosyn y Twyni) Irish name: Briúlán

There is a glorious stretch of these lovely and very prickly roses on Bryn Euryn that are fully in flower now.

Beautiful Burnet Roses

The Burnet Rose is a low-growing species, largely confined to dry sandy places near the sea; it is particularly abundant on dune systems in South Wales. Inland it may be found in calcareous areas, generally chalk downland or limestone pavement.

 Its natural distribution is limited to Europe and Asia except for part of the Atlas Mountain Range in North Africa.

It is a rather low erect deciduous plant usually growing to 20–140 cm high but it can sometimes reach up to 2 metres.

The plant spreads by suckers and can cover large areas. The stems are protected by numerous stiff bristles and many sharp straight prickles. The young stems and prickles and the mature leaves tend to be very red with young growth a bright scarlet and older growth a deep maroon.

 ‘Some people are always grumbling because roses have thorns. I am thankful that thorns have roses’.

  Alphonse Karr (1808-1890)

The flowers are cream-white although rarely also pale pink and are 2–4 cm in diameter with five petals. prominent golden stamens and they have the sweetest, most delicious scent of any of native roses.

Popular with bumblebees

Bumblebees seem to love them, perhaps because they do have a hint of honey in their scent.

Soon the petals fall off the roses but the stamens look pretty too. The leaves are small and oval, very like those of the salad burnet (hence the name).

And later in the year there will be a crop of  distinctive globular dark purple to black hips.

A brilliant-orange rust fungus Phragmidium rosa-pimpinellifoliae is also common on the plants.

The plant’s names 

R. spinosissima (pimpinellifolia) has been known by many different local names and it has attracted its own folklore. In some places, people have given it a vernacular name based on the resemblance of the leaves to a Burnet (Sanguisorba ) and therefore, for example, called it the Burnet or Pimpinell Rose in English or Rose Pimprenelle in French. In other places, it was the prickly stems that caused it to be known as Bodicasti Sipek in Slovenia, for example, or Piikkiruusu in Finland.

In Iceland, it has the name pyrinros which literally means ‘Thorny Rose’ but the same Icelandic word means ‘Sleeping Beauty’ and may refer to its early flowering – the beautiful rose waking up after the long dark Icelandic winter! In Norway, this rose is called ‘Trollnype’ – associating it with the trolls of Norwegian folklore. Elsewhere, it is named after the coastal sand-dunes where it grows so, for example, it is Klitrose in Denmark,Duinroos in The Netherlands or Dünen Rose in Germany.

Medicinal uses

The plant  was initially grown in gardens for its herbal properties and it was one of the first roses described and illustrated in 16th  century herbals of Northern Europe. Its hips and leaves have been used to make a tea and, in some places (particularly Denmark) a liqueur is still made from its hips. In recent years, it has been the subject of intense research to investigate its special pharmaceutical properties. The chemical constituents have recently been summarised by Mayland-Quellhorst et al (2012). Its dark purple or black ‘fruits’ (heps) are high in vitamins and antioxidants.

Pretty prickly Thistles

05 Monday Aug 2013

carduelis carduelis, cirsium arvensis, cirsium vulgare, creeping thistle, Goldfinch, scotch thistle, spear thistle, thistle folklore and mythology

Thistle is the common name of a group of flowering plants typically characterised by leaves bordered with sharp prickles, mostly belonging to the family Asteraceae.  Prickles or spines are not always confined to the margins of leaves, often occurring all over the plant on surfaces such as those of the stem and the flat parts of leaves. These are a defensive adaptation that protects the plant from being eaten by most herbivorous animals.

From an agriculturalist’s point of view, the most common thistles are regarded at best as troublesome weeds and at worst as noxious ones. However, ecologically, the leaves of some species provide a valuable food source to the larvae of a number of lepidopterae species and he flowerheads supply pollen and nectar to an array of adult insect species. Thistle seeds are a favoured food of many members of the finch family Fringillidae, whose genus name, Carduelis, is derived from carduus, the Latin name for thistle and includes goldfinch, greenfinch and linnet.

1- SPEAR THISTLE – Cirsium vulgare

Family: Asteraceae; Flowering: July to September; Habitat: Disturbed and cultivated land such as pastures, meadows, roadsides, arable fields, gardens, brownfield sites and waste ground.

A widespread and common thistle, the Spear Thistle has the classic thistle appearance – purple, fluffy-looking flowers sitting atop a spiny ball and may well have given rise to the Scottish national emblem. As with other thistles, it can become a nuisance on agricultural land and is often considered to be a weed. The spear thistle is usually a biennial plant although the leaf rosettes can survive as long as 4 years before finally flowering. This robust thistle can reach between half and over a metre in height under favourable conditions. The plant is often solitary.

The flowers are lilac or magenta and are larger than creeping or marsh thistle flowers, reaching up to 4 cms in diameter. Stems are winged and spiny. The leaves are spear-shaped, pinnately-lobed and spiny and give the plant its common name. The upper surface ranges from dark green to light grey. The under surface is green. The leaves are waxy and end in sharp “spear-like” prickles which are tipped with yellow.

The average number of seeds per flower head is around 100 but there can be up to 340. Seed production per plant may vary from 1,600 to 8,400 seeds. More seeds are produced when ample soil moisture is available during the growing season. Seeds are mostly dispersed during August and September.

Spear thistle seeds

Spear thistle seeds

Spear thistle spreads only by seed. Unlike creeping thistle (C. arvense), the feathery pappus remains attached firmly to the seed as an aid to wind dispersal. Most seed is dispersed less than 2 m from the parent plant and only 10% travel more that 32 m after reaching higher air currents.

Ecology

Thistle flowers are amongst the favourite nectar sources of the Pearl-bordered Fritillary, Small Pearl-bordered Fritillary, High Brown Fritillary, and Dark Green Fritillary butterflies.

The seeds are attractive to ants that may aid their dispersal and also to finches, particularly goldfinches and linnets.

Scotland’s National Emblem 

This thistle, seen throughout Scotland and the Western Isles has been Scotland’s national emblem for hundreds of years. There are several versions as to how the thistle became Scotland’s symbol, most are set around the reign of Alexander III (1249-1286) and in particular the events surrounding the Battle of Largs in 1263.

At one time, Scotland was part of the Kingdom of Norway although it attracted very little interest until 1263 when King Alexander III proposed to buy back the Western Isles and Kintyre from the Norse King Haakon IV. That provoked King Haakon of Norway and in the late summer of 1263 he set off for the Scottish coast with a large fleet of long ships, intent on conquering the Scots. Gales and fierce storms forced some of the ships onto the beach at Largs in Ayrshire, and a Norwegian force was landed.

Legend has it that at some point during the invasion the Norsemen tried to surprise the sleeping Scottish Clansmen. In order to move more stealthily under the cover of darkness the Norsemen took off their shoes, but as they crept barefoot they came across an area of ground covered in thistles and one of Haakon’s men unfortunately stood on one and shrieked out in pain, thus alerting the Clansmen to the advancing Norsemen. His shout warned the Scots who defeated the Norsemen at the Battle of Largs, thus saving Scotland from invasion. The important role that the thistle had played was recognised and so was chosen as Scotland’s national emblem.

The Order of The Thistle

In 1470 that King James III ordered that the image of this plant’s flower be placed on silver coins and also then a little later In 1540, King James V established the Order of the Thistle, a high chivalric order of Scotland. He and his 12 knights each wore a badge depicting a star, a thistle and the words “no one harms me without punishment.”

Today the thistle is found in many Scottish symbols and is used as part of the name of several Scottish football clubs. The thistle, crowned with the Scottish crown, was the symbol of seven of the eight former Scottish Police Services (from which a new national Police Service was formed in 2013), the sole exception being the former Northern Constabulary. The thistle is also the emblem of Encyclopaedia Britannica, which originated in Edinburgh, Scotland.

The Thistle is also used to symbolise connections with Scotland overseas. In Canada, it is one of the four floral emblems on the flag of Montreal; in the United States, Carnegie Mellon University features the thistle in its crest in honor of the Scottish heritage of its founder, Andrew Carnegie.

2 – CREEPING THISTLE – Cirsium arvense 

Family: Asteraceae; Flowering: June to October; Habitat: rough grassy places : pastures, meadows, roadsides, arable fields, gardens, brownfield sites and waste ground.

Creeping Thistle is a native, perennial, rhizomatous herb, which forms extensive spreading patches and grows up to 2m+ in height. It is one of our most widespread and troublesome weeds and is listed as a noxious weed in Britain under the 1959 Weeds Act, although to little effect. It appears resistant to herbicides and readily regenerates from rhizome fragments caused by ploughing. It is also a very valuable source of nectar, pollen and seed food for many insect specicies.

Flowerheads of Creeping Thistle-Cirsium arvensis

Female flowerbuds are oval  in shape

Flowerheads are pale lilac in colour and up to 2cm across. Female flower buds are oval in shape; male flower buds are slightly more spherical. Bracts are purplish with spreading spiny points. Stems are smooth and spineless. Leaves are very spiny, stiff and wavy.

Pollination

The male flowers produce abundant pollen. The fragrant female flowers are insect pollinated but the pollinators may only visit one type of flower.

The time from flowering to seeds becoming viable is around 8-10 days. Seeds ripen from June to September and are shed from August onwards. There may be 20 to 200 seeds in each flower head and an average of 680 seeds per stem. The seed number per plant ranges from 1,600 to 50,000.

Ecology

Creeping Thistle foliage is used as a food by over 20 species of Lepidoptera, including the Painted Lady butterfly and the Engrailed, a species of moth, and several species of aphids. The flowerheads provide nectar and pollen for a wide variety of insects.

Family: Asteraceae; Flowering: July to September; Habitat:
Wet habitats, woodland clearings, wet ditches and marshes.

A biennial, medium to tall plant reaching to 1.2 metres, stems spiny-winged to the top, sometimes branched above.

Flower buds are oval and bracts are purplish above and green below – sometimes cottony. Flowerheads are usually purple, 10 to 15 mm across and held in clusters of 2 to 8. Florets are reddish purple and anthers are blue-purple. The stem is winged and spiked. Leaves are linear lanceolate, pinnately lobed and very spiny, mostly unstalked, hairy above.

The pappus is slightly feathery.

This species may be confused with the Welted Thistle – Carduus crispus but can be distinguished by its feathery seeds. Welted Thistle has seeds with down that is unbranched.

Late summer on Bryn Euryn

The soggy conditions created by the rainfall this year have not been ideal for many late summer wildflowers and, perhaps as a result of that, it seems to me that there has been a drop in some insect populations. I was on the lookout for flower beetles, in particular soldier beetles, which in  previous years have been prolific, and struggled to find many at all.

I spent a couple of hours roaming the pathways of Bryn Euryn on one sunny afternoon in mid-August, ignoring grey clouds rolling in at my peril, getting caught right at the top in a proper downpour. There is  almost always something interesting to photograph here whatever the weather though, and these are my offerings for that day.

There were very few plants still flowering on the lower field edge, but the first one, the Great Willowherb, often mistaken for Rosebay Willowherb, is one I’ve wanted to mention for a while and will do at greater length soon.

Self-heal- Prunella vulgaris

In the clearing at the top of the steps that cut through the lower woodland is a bramble patch that always seems to attract an array of nectar-seeking insects. Today there were a good number of hoverflies, most the one photographed below, but there were a few other Eristalis species too.

This attractive hoverfly is Helophilus pendulus, common names are Sun Fly as it does enjoy basking in sunny patches, and The Footballer referring to its colours and stripy patterning

Eristalis on Wild Carrot- Daucus carota

I headed a bit round to the open grassy area that this time last year was covered in purple flowered knapweed and buzzing with dozens of insects,  but now was looking quite bedraggled and bereft of colourful blooms. There was some knapweed, but hardly enough to go around apparently as most of the flowers had more than one bumblebee or hoverfly competing for its bounty.

Black Knapweed-Centaurea nigra

Red-tailed Bumblebee on knapweed flower

In amongst the long damp grass was a pink flower that I recognised from last year but didn’t get around to identifying. This (I believe/hope) is an unusual plant of the allium family, common name Nodding Wild Onion or Allium. The pink bell-shaped flowers are  tiny and have protruding stamens; very pretty.

There were a few plants of Agrimony – Agrimoniia eupatoria

The other staple of late summer nectar, Ragwort, is also flowering of course. I can’t not include it here, so thought I’d just put in a close-up of an individual flower to show how pretty they really are.

One flowering plant that is relishing the damp conditions and flowering prolifically here was Hemp Agrimony. Its flat, open flowers are very attractive to insects; great for butterflies.

Hemp Agrimony-Eupatorium cannabinum

There were a few butterflies about, but as the clouds came over and the air cooled those that were out and about were not very mobile. Meadow Browns were most numerous but most were fluttering about low down in the long grass. I spotted one on Hemp Agrimony, also a single Gatekeeper and was taken by surprise when a Peacock (butterfly!) flew right in front of my face. I did photograph them all, but by now it was minutes away from the onset of the downpour and quite dark, so the resulting images are a bit grainy, but there for the record.
