Random Insect: Spicebush swallowtail butterfly

Spicebush swallowtail butterfly (Papilio troilus, Papilionidae) photographed 06/12/2011 near Blissfield Michigan.

Last August I photographed a black swallowtail (Papilio polyxenes, Papilionidae), and when I found this butterfly in a southern Michigan greenhouse I initially thought it was the same thing.  A closer inspection of the markings on the undersides of the hind wings revealed it was actually a spicebush swallowtail (Papilio troilus, Papilionidae).  Members of the genus Papilio share similar markings and it’s necessary to scrutinize them closely to distinguish them.  Although rather common in this area, they’re nevertheless beautiful.
