Thanks for the ID!See the double row of yellow on the edge of the inside of the wings = black swallowtail.. Someone else may know how to sex them.
Excellent!Yes, this is a Black swallowtail, papilio polyxenes asterius. For the sex, I would say it's a female since the male have almost no blue mark on the bottom wings, and females have a lot of them.
Just what I was waiting to hear!This is a gravid female.
