Chap found this little fellow yesterday on the ground underneath a neighbour’s aspen tree. Isn’t he stunning? Such gorgeous colours.
It’s the caterpillar of a poplar hawk moth (Laothoe populi), and I gather they feed on aspen, poplar and willow leaves. The aspen leaves are starting to fall so he might have been on one when it tumbled off the tree.
I hope he wasn’t hurt—we aren’t sure what the clear liquid is, but hope it might be some sort of defence mechanism rather than indicating he is injured.
He’s such a gorgeous lime green colour with four rows of maroon spots, and matching bootees! Chap put him back under the tree: he’ll dig a hole and pupate there, and hatch out next year as a beautiful moth.
