Caterpillars in November

Though I know many Lepidoptera over-winter as caterpillars, and this has been a particularly mild November as well, it was still a surprise to see these two caterpillars on one of my recent walks. From previous sightings, I knew that the black, red and white hairy beastie was the larva of a Knot grass moth (Acronicta rumicis) but I didn’t recognise the other one. One of my Twitter pals was able to tell me it’s one of the Noctuid species of moths but wasn’t able to be more specific, but I’ve just ordered a book I’ve long desired, The Field Guide to Caterpillars of Great Britain and Ireland, so will hopefully be able to update this post soon.

When I spotted this caterpillar yesterday, I didn’t think I’d seen one like it before but, when one of my Twitter pals later identified it for me, I realised I had seen one previously, though a younger model.

These are the larvae of the Knot grass moth (Acronicta rumicis), a moth I’ve never seen (you can see what the adult moth looks like and read more about it on the UK Moths website). I think the larva above, found munching on Dyer’s greenweed at Cosmeston on 4 June, is an early instar, whereas the larva below, found feeding on Common ragwort at Lavernock Nature Reserve on 10 September and a real stunner, is almost ready to pupate for the winter.

This tiny tufty character was a surprise find during yesterday’s walk.

I guessed it was a moth caterpillar but had no idea which, so posted some photos on Twitter. It only took a few minutes for my moth-er contacts to give it a name – this is the larva of the Knot grass moth (Acronicta rumicis).
