I have a question I pulled about 30 eggs from black swallowtails off my one fennel plant l that I had and all the eggs hatched now I have a bunch of small caterpillars and I had had three big previous ones and ran out of Fennel. my husband bought parsley from the grocery store and set it I the there with the three big ones then they were about dead this morning and I was
Wondering if there's a possibility there may have been something like pesticides or something on the parsley that wouldve caused this? I've never dealt with this before so I don't know if anybody might have any suggestions on what happened
