Hi
I have 20 viceroy caterpillars that are first or second instar. And I have no Idea on how to overwinter them. I thought if I pinned them to a tree and put a net or something over them to protect them it might work. Or if I pinned them to my potted willow and put the potted willow in the shed. If anyone else has any ideas or your techniques PLEASE HELP.
