Eastern Swallowtail Butterflies

The Monarch butterflies have moved into the neighborhood and are everywhere. I've now set my sights on finding Eastern Swallowtail butterflies.

It's easy to find Monarch butterflies, just look for Bull thistles.
After a lot of looking (mowing fields) I found this Eastern Tiger Swallowtail (Papilio glaucus) on a Bull thistle.
This is a male Eastern Tiger Swallowtail, the females have blue markings along the hindwing. Some female Eastern Tiger Swallowtails are dark-colored with a marginal row of yellow spots.
The blue markings along the hindwing identify this Eastern Black Swallowtail (Papilio polyxenes) as a female.
