Question by Elizabeth E: I think I have 3 black swallowtail caterpillars in my herb garden. How long before they pupate?
They are about 2″ and I’m worried about having enough food source for them.
Answer by Me
Leave them where they are. They chose that location instinctively.
They should be butterflies in about a week since they form the cocoon
