Eastern Tiger Swallowtail (dark form)

This is an Eastern Tiger Swallowtail. Most Eastern Tiger Swallowtails are yellow with black tiger stripes like this one here: www.flickr.com/photos/texaseagle/3283987246/

 

But the one above is a female dark form Eastern Tiger Swallowtail. In the dark morph, most of the yellow areas are replaced with a dark gray to a black. A shadow of the "tiger stripes" can still be seen on the dark females.
