The Zebra Swallowtail (Protographium marcellus, formerly listed under genera Eurytides, Iphiclides, Graphium and Papilio by some authorities) is a swallowtail butterfly native to the eastern United States and southeast Canada. Its distinctive wing shape and long tails make it easy to identify, and its black and white-striped pattern is reminiscent of a zebra. The butterflies are closely associated with pawpaws, and are rarely found far from these trees.
