Indet. Caterpillar 1a
Funny little inch worm. We spotted this as we were going through a kissing gate from a meadow. It was quite still and then started waving around looking for something to grab onto. It finally gave up and inched off and quite a pace.
I can't ID this, but I'd hazard a guess that it's a Wave moth of some kind.
I think the gate was under an oak.
