what plants do butterflies spin their cacoon on or their eggs thank you

Wildlife Expert - Ken Burton

It depends on the species. Each butterfly species has its own set of preferred host plants; some are pretty picky, others less so. As a rule, butterflies lay their eggs on their caterpillars' food plants and the caterpillars then spin their cocoons (not "cacoons") on the same plants, though many drop to the ground and pupate there, especially if they'll be there all winter.
