In Saturday’s post we had the small and scary (if you don’t like spiders – personally, I thought they were adorable); today we have the small and hairy, a web of Lackey moth caterpillars (Malacosoma neustria), which can often be found at this time of year, their web wrapped around the twigs of various broadleaved trees and shrubs.

The early instar (youngest) larvae don’t show the blue side stripe or ghoulish face, which make these larvae so distinctive as they grow.

These were a surprise on a chilly and very foggy early morning walk earlier this week.

I suppose I should have realised that some caterpillars overwinter as larvae but I was still amazed to find all but one of these four sitting in plain sight, fully exposed to the weather, covered in dew drops. I’m reliably informed these are the larvae of the Angle shades moth (Phlogophora meticulosa).

Leafmines: Scrobipalpa acuminatella

This week’s mines can be found on thistles, on species of both Cirsium and Carduus – in my case, the plant is Creeping thistle (Cirsium arvense).

211115 Scrobipalpa acuminatella (1)

These mines have been made by the larvae of the moth Scrobipalpa acuminatella, the adult of which can be seen on the UK Moths website. As the website points out, these moths have two generations each year, so we get two chances to see the mines.

These moth larvae make their home in the midribs of thistle leaves, venturing out to eat during the night and making blotches as they do, then returning to the midrib to shelter during the daytime.

British insects, moth caterpillars, moth larvae, mystery caterpillars, mystery larvae, sawfly caterpillars, sawfly larvae

To showcase their diversity, in colour, size, shape, pattern, habits and hairiness, I’ve been gathering photos of these (cater)pillars of the insect community, the larvae of moths, sawflies, and some mysteries, which could be one of these … or something other. Here they are:

210930 moth 5-spot burnet
210930 moth drinker
210930 moth maiden's blush

Moths: 5-spot burnet (Zygaena trifolii), Drinker (Euthrix potatoria), and the delightfully named Maiden’s blush (Cyclophora punctaria).

210930 sawfly Allantus sp
210930 sawfly Eriocampa ovata

Sawflies: a possible Allantus species (its identity cannot be confirmed as it was on the wrong plant), and the fluffy looking Eriocampa ovata.

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.

210818 buff tip moth larvae (1)

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.

Spindle ermine

It could be Halloween, with reports of ‘ghostly silken webbing’ that ‘can look rather sinister’ and give trees ‘an eerie appearance’. As well as covering parts of trees and hedgerows, apparently the webs are sometimes ‘so extensive that they can cover nearby objects such as benches, bicycles and gravestones’.

But this is June and in my local woodland, the one I showed you in yesterday’s post, the webs, though plentiful, are nowhere near that dramatic. These are the communal dwellings of moth larvae and, though there are several species of ermine moths, as the caterpillar-filled webs I’ve been seeing have all been on Spindle, I think I’m safe in assuming these are the larvae of Spindle ermine (Yponomeuta cagnagella).

210624 spindle ermine (3)

Although these are the first webs I’ve seen, the Butterfly Conservation website reports that Spindle ermine is a common resident, though it is less common in northern parts of Britain. Look for Spindle trees and you might well see these webs for yourself.

Oak: mothy goodness

As you can see from the last two days’ blogs, there was much to be found on Oak leaves in my local woodlands on Sunday. These are two more finds, both relating to moths. This first was found on the same tree as the Purple hairstreak larva and, thanks to some help from Twitter moth-ers, I can tell you this is the larva of the Brindled green moth (Dryobotodes eremite) (you can see the adult moth on the UK Moths website here).

210527 brindled green larva

The wonderfully crafted cases in the photos below contain the larvae of either Coleophora lutipennella or Coleophora flavipennella – apparently, it’s not possible to determine the species without waiting for the adult moths to hatch and then dissecting their genitalia, which I’m not going to do. I’m happy just to admire their silk-weaving skills.

First caterpillar

British caterpillars, British moths, moth caterpillar, moth larvae, Scarlet tiger, Scarlet tiger moth larva

Most unexpectedly, I saw my first caterpillar of the year when I was out walking yesterday. It’s a Scarlet tiger moth caterpillar that was sitting on the stucco wall of a house I passed. According to my Twitter pal George, who’s a senior moth ecologist with Butterfly Conservation, though Scarlet tigers over-winter as larvae, these larvae are not usually seen until the spring. But spring is only a couple of weeks away and, if local bird activity is anything to go by, the wild creatures can already feel it in the air.

George reassuringly told me that caterpillars are tough but I do hope this little one finds somewhere a bit more sheltered to weather the cold spell that’s forecast for the coming week. I’d love to see it again when it emerges as an adult as they’re so beautiful and I’ve only ever seen the adults twice. The photo below, of a Scarlet tiger moth, was taken locally in June 2019.

331/366 Leaf mines: Phyllonorycter leucographella

I stumbled across these leaf mines by accident but I simply can’t resist including them … because the tiny striped larvae are so darn cute!

201126 phyllonorycter leucographella (1)

These are the larvae of the moth Phyllonorycter leucographella, the adult of which is also rather striking – you can see photos of it on the UK Moths website here. As the website reports, this moth is a recent arrival to Britain, first spotted in Essex just 40 years ago, but for such a small creature – its wingspan is only 7-9mm – it’s managed to fly and settle far and wide, from Yorkshire in the north of England to Pembrokeshire in the west of Wales, and all points in between. This may partly be due to the fact that its larvae feed on many garden plants: I found an abundance of leaf mines on an orange-berried variety of Firethorn (Pyracantha coccinea), which explains why the moth’s common name is Firethorn leaf miner.

As you can see from my pictures, the larval ‘mine’ is like a blister, centred over the midrib on the upper side of the leaf. The larva, which, with black blobs on a white body, is very distinctive, can often be seen through the membrane of the mine, especially when it’s feeding at the edge of the blister. You can read more about this leaf miner, its life cycle and preferred larval plants on the UK Fly Mines website here.

307/366 Leaf mines: Tischeria ekebladella

blotch mines on Oak, British moths, leaf mines on Oak, moth larvae, moth larvae in leaf mines, moth leafmines, Tischeria ekebladella

I mentioned in a recent post (Gone galling, again, 28 October) that October was a good month to find galls and mines on leaves and, in fact, that also extends into November, or until the deciduous trees have shed their leaves and those fallen leaves have turned to mush, and the leaves of wild plants have also become unrecognisable in the mud under our feet.

201102 Tischeria ekebladella (1)

So, let’s start this mini series on leaf mines with a look at the blotch mines made on Oak (and sometimes Sweet chestnut) by the larvae of the micro moth Tischeria ekebladella. The blotch starts off looking quite white but often browns, from the centre, with age, giving it a look that one astute observer described as a fried egg. The larva creates a cocoon within the blotch and remains there until its ready to pupate in the springtime. The adult moth emerges from pupation and is on the wing in May and June.

By holding leaves up to the light, I managed to photograph larvae within a couple of mines, though, one of our local moth experts, George, who’s a senior moth ecologist with Butterfly Conservation, told me that the larva in the photo on the right below looks to have been parasitised and a different creature’s larva seems to have emerged from the Tischeria larva. Such is the way of Nature.
