Not often have I tried to overwinter caterpillars but when I have, I've failed. This year, not exactly intentional, I'm trying to rear various eggs collected in August. Last night (09-28-18) we had a first frost so a hard frost will be coming.
What do I do with the cats?
I can't just suddenly cut off their food (because there isn't any) and stick them in the fridge as I would pupae (usually end of October).
Thank you for any advice and help.
