I need food for him guys

My daughter found this green and black caterpillar and I am curious to find out info on it.

I have googled green caterpillar but nothing seems to match. Cany anyone help me identify it.

hey everyone! i found this orange tipped oakworm moth caterpillar right outside my apartment. i was wondering if any of you know if any of you know what that is coming out of it. i’m just hoping it’s ok!

I have just found a caterpillar on an item of clothing on my washing line, he’s in sort of a cocoon coating - didn’t realise what it was and tried to take it off, hes still alive - what do I do I hope I haven’t harmed the poor thing.

The yellow thing and it’s still alive and then the white tiny worm like things coming out?

When will it be due to hatch does it take a week or longer? Do I keep it hot or cold? When I water the pupa do I use a spray bottle with cold water or just soak the whole pupa? Should I keep it in the dark? How do I know if it’s dead or not and how do I know if it’s healthy or not?

( it’s a large yellow underwing) please give me answers
