Eastern Tiger Swallowtail Butterfly, Papilio glaucus,
on Canadian Thistle, Cirsium ravens
I photographed this Eastern Tiger Swallowtail in my yard as it was feeding on Canadian Thistle. This species is numerous around my home and can be seen most of the summer. The Easter Tiger Swallowtail is Alabama's state butterfly, and is one of the most common swallowtail butterflies throughout the eastern United States and Canada.
