Zebra Swallowtail


The Zebra Swallowtail (Protographium marcellus) has a wingspan of 6.4 to 10.4 cm.
It occurs in most of the states of the eastern USA, and in Cuba.
It is the state butterfly of Tennessee. 
Its distinctive wing shape and long tails make it easy to identify, and its black-and-white-striped pattern is reminiscent of a zebra. 
A red stripe runs along the middle of the ventral hindwing. 
The Zebra Swallowtail has two seasonal forms, one occurring in the spring and the other in the summer. 
Spring forms are smaller, more white, and have short, black tails with white tips. 
Summer forms are larger, have broader black stripes, and longer, black tails with white edges
These butterflies are closely associated with pawpaws, and are rarely found far from these trees.
