We live in zone 5 Medina County Ohio and the past two years I have taken an interest in the butterflies due to my daughter who grows veggies; the first cat seen on parsley of a black swallowtail in 2015. This past winter a black swallowtail wintered over in our unheated garage and just yesterday the chrysalis opened and flew away. I think this cat was found in our yard on fennel around in September, 2016. Brought in the house and placed in an aquarium. So excited that this swallowtail survived. Didn't get to see it fly away though. Here is a picture of it in the aquarium after coming out of the chrysalis. I have planted a lot of milkweed for the monarchs in the fall and really happy so many are coming up. Hope to have a good butterfly season! Plant for the butterflies and make yourselves happy! Sandy
