Three blues

After spotting my first damselflies of the year (Large reds) on 21 April, there was quite a lull (probably dull-weather-induced) until any further species appeared. But, on a warmer, sunnier day last week (3 May), all three of the more common blue species appeared together. They are:

‘Modestly cheerful’ – this is how Richard Mabey describes Common whitlowgrass (Erophila verna) in Flora Britannica. He continues: ‘The small white flowers are amongst the first to appear in March, and are followed by seed-pods a little like miniaturised versions of honesty’s.’

He also explains that the name is due to the plant’s use by medieval herbalists to treat whitlows, not a medical condition I was familiar with but which the Oxford Dictionary defines as ‘an abscess in the soft tissue near a fingernail or toenail’. I don’t recommend a Google image search as the condition looks quite gruesome, but these wildflowers, often present in large massed displays, are a delight.

Moult (US molt): noun and verb; (of an animal) shed old feathers, hair, or skin to make way for new growth; origin: Middle English moute, from an Old English verb based on Latin mutare ‘to change’ (Oxford Dictionary).

Today’s word is inspired by this moulting Woodlouse I found in nearby woodland last week.

Today’s lovely long meander took me to Cosmeston Lakes Country Park, where I watched a large flock of Fieldfares and Redwings worming in the west paddock, enjoyed the antics of the almost-tame Crows that are feed daily by a regular visitor and now expect all humans to feed them, and chuckled at the small birds squabbling over which would get the sunflowers amongst the seed I dished out. The Nuthatches won that game most of the time, repeatedly nabbing two and three at a time to take away and stash for later consumption.

Fungi come in an amazing variety of forms and colours. Here’s one I found for the first time a week or so ago.

211029 Dothidella ulmi (1)

You’re probably familiar with Sycamore tarspot (Rhytisma acerinum), which makes black spots on the leaves of Sycamore trees. Well, this is superficially similar, though not as widely recorded in Britain: it’s Dothidella ulmi, a fungus that develops under the epidermis of leaves on Elm trees, in this case Wych elm, then erupts in a mass of grey blisters.

It’s quite the transformation, from this green larva that looks a bit like a cross between a slug and a caterpillar …

210904 scaeva pyrastri (1)

to this black-and-white flying creature.

210904 scaeva pyrastri (2)

This is the hoverfly Scaeva pyrastri and, amazingly, it’s a migrant from mainland Europe. A bit like the Red admiral butterfly, Scaeva pyrastri has good years and bad years, sometimes visiting lowland Britain in large numbers, sometimes hardly at all. And, when it comes here, it does often breed locally (and here, I must add a caveat – the larva in my first image may actually be the other Scaeva species, S. selentica, though that species hasn’t actually been recorded in my area).

Thanks to a chat with local expert birder, Graham, I saw splashes of autumn, the flashing orange-red of a young male Redstart, at Cosmeston yesterday.

And he – the bird that is, not Graham – certainly wasn’t shy about displaying the glorious colours under his tail and wing, as he flitted from bush to ground to small tree to wire fence in his constant search for food.

There was another bird calling constantly very close by, probably a second Redstart, but I didn’t manage to get on to it before getting a message that there were Whinchats on the other side of the park. I love this time of year – you never know what’s going to turn up next.

Buff-tip larvae

I’ve never seen a Buff-tip moth (Phalera bucephala) except in photographs (they look incredibly like twigs – see images on the Butterfly Conservation website here). But yesterday I found their larvae, lots of them, all huddled together on the top side and underside of an Oak leaf.

The adult moth, which flies from May to early August, lays clusters of eggs under the leaves of the trees their caterpillars feed on, which, as well as Oak, include Hazel and the various birches and sallows, amongst others.

The larvae hatch out after 2-3 weeks and start eating. It takes just a month for them to go through their four instars, after which they move down into the ground to pupate. Come the spring, the whole process begins again.

August is the time of the crickets, when many species mature from nymph to adults and the males begin their night-time wing-against-wing-rubbing (called stridulation) to advertise their presence.

210816 dark bush-cricket

I found this Dark bush-cricket sunning itself on a bramble bush. It started to move under a leaf as I approached with my macro-lensed camera but then kindly consented to pose for some images. It’s such a handsome beast, with its dappled brown body armour.

210816 speckled bush-cricket

This Speckled bush-cricket also wasn’t sure about me getting so close but somehow sensed I wasn’t a threat. She’s a stunning female – the dagger-like appendage on her rear is her ovipositor, used to lay eggs in tree bark and plant stems.

The spider and the fly

I was watching this well-camouflaged Crab spider (probably Misumena vatia) restraining its prey when a mother and young son came walking along the path towards me. I could see and hear that the woman was pointing out various flowers and insects to her son so, rather than immediately step out of their way, I asked the boy if he wanted to see something cool. I pointed to where he should look and moved away a little, still conscious of maintaining a Covid-safe distance.

He was spellbound as I explained that the spider had been sitting on a white flower so it could use its white colour to trap the fly. He thought the spider was ‘sneaky’, and I could hear him and his mother still talking about the spider and ‘amazing Nature’ as they walked on. Well done to his mum for encouraging the boy’s interest. I think it’s so important that young people are inspired to look closer at the amazing natural world that surrounds them.
