Looking daggers at me?

Yesterday, when I was checking out some local Oak trees for leaf mines, I came across this vibrant character. It turns out this is the larva of the Grey dagger moth (Acronicta psi), a very colourful creature when compared with its parent (you can see images on the UK Moths website here).

The larvae are about from July through to November and can be found on a wide variety of food plants. They are much easier to identify than their parents: the Grey dagger is almost identical to the Dark dagger moth and an examination of their genitals is required to tell them apart. I’m so glad I found the caterpillar not the moth – and I don’t really think it was looking daggers at me!

Horse chestnut leafminer

You may well have noticed that many (most?) of the Horse chestnut trees around you are starting to look a bit manky. Their leaves have become covered in white and brown blotches.

Those blotches are actually leaf mines, home to the larvae of Cameraria ohridella, the Horse chestnut leaf-mining moth (the brown blobs in the mines). According to the UK moths website

This species was discovered near Macedonia in 1985, and since then has spread rapidly to other countries in Europe. It was first discovered in Britain at Wimbledon in south-west London in 2002, but possibly had arrived the previous year, as it was quite plentiful. It is thought that the species may be expanding partially due to accidental transportation by man, either by road or rail. It has now been found quite extensively in the south-east of England.

Obviously, since that website entry was written, the moths have now spread from south-east England to south Wales and, indeed, to parts much further north. You’re mostly likely to see the blotches between June and September and, though you might not like the look of them, they’re not thought to inflict any permanent damage on the tree because, of course, the leaves are shed in the autumn anyway.

Moth trapping at the Obs

These are just a few moths from last weekend at Portland Bird Observatory in Dorset. They trap every night at the Obs and, because of their southern-coast location, just as with the birds they also get many migrant moths. However, I was too busy birding to take many moth photos and I’m fairly sure these are all common Brits. They’re not species I would necessarily see in Wales though and they are pretty, especially that third one (bottom left).

171022 Black rustic
171022 Feathered Brindle
171022 Green-brindled crescent
171022 Lunar underwing

These are: Black rustic (Aporophyla nigra), Feathered Brindle (Aporophyla australis), Green-brindled Crescent (Allophyes oxyacanthae), and Lunar Underwing (Omphaloscelis lunosa).

171022 Fox moth caterpillar

While out walking the cliff-top paths on Saturday afternoon, one of our team also found this little fella pottering along on the grass beside the track. It’s a Fox moth larva (Macrothylacia rubi).

We also spotted a ton of these webs in the brambles near the main lighthouse. They house the larvae of Brown-tail moths (Euproctis chrysorrhoea).

March of the caterpillars

Aglais io, butterflies, caterpillar, Euproctis similis, Lasiocampa quercus, moth larvae, moths, Oak eggar, Peacock butterfly, Yellow-tail

Perhaps that should really be MUNCH of the caterpillars because these little creatures are really the ultimate food processors. They eat ravenously, they ingest determinedly, they process interminably, and, yes, they pooh prodigiously. What a life!

170620 Oak eggar larva (1)

They can be covered in bristles: watch these ones as people with sensitive skin often get a rash from touching them because they can contain chemicals to deter predators from eating them. They can be dull to blend in with the vegetation on their favourite food plant. They can be patterned in startling colours and patterns, again as a warning to predators – ‘Don’t eat me!’

170620 Oak eggar larva (3)
170620 Yellow-tail larva (3)

These particular caterpillars are the larvae of two moths and one butterfly. The hairy ones are the moths, Oak eggar (Lasiocampa quercus) and Yellow-tail (Euproctis similis), and the spiky black one with white dots is the rather surprisingly coloured caterpillar of the Peacock butterfly (Aglais io).

caterpillar, Drinker moth caterpillar, Large rose sawfly caterpillar, moth larvae, Old lady moth caterpillar, Pale tussock moth caterpillar, Ruby tiger moth caterpillar, Vapourer moth caterpillar

Caterpillar:
Noun. Pronunciation: /ˈkatəpɪlə/
1. The larva of a butterfly or moth, which has a segmented body resembling a worm with three pairs of true legs and several pairs of leg-like appendages.
1.1. (In general use) any insect larva resembling the larvae of caterpillars and moths, especially that of the sawfly. (Oxford Dictionary)

Here are some examples I’ve spotted of these insect larvae.

Cinnabar (1)
Cinnabar (2)

These black-and-yellow striped critters are Cinnabar moth caterpillars (Tyria jacobaeae), chewing away on their favourite food plant, ragwort.

Parsnip Depressaria pastinacella (1)
Parsnip Depressaria pastinacella (2)

The caterpillars of the Parsnip moth (Depressaria pastinacella) build themselves little silken webs within the structure of the umbellifer flowers (in particular Wild parsnip), on which they feed.

1 Drinker Philudoria potatoria
2 Old lady Mormo maura
3 Vapourer Orgyia antiqua
4 Sawfly rose larva CathaysCem
5 Ruby tiger methyr mawr
6 Pale Tussock Calliteara pudibunda

A snapshot of a few others I’ve sighted (from left to right): Drinker moth (Philudoria potatoria), Old lady moth (Momo maura), Vapourer moth (Orgyia antiqua), sawfly larva (possibly of the Large rose sawfly, Arge pagana), Ruby tiger moth (Phragmatobia fuliginosa), and, lastly, the wild extravagance of the Pale tussock moth caterpillar (Calliteara pudibunda).
