The zebra swallowtail has a wingspan of about two and one-half to four inches. Its wings are pale green-white with black stripes. The projection from the rear edge of the hindwing, the “tail,” is fairly long. The larva is green with yellow and black bands.
The zebra swallowtail may be found statewide in Illinois. The larva eats leaves of pawpaw trees and related plants. The adult ﬂies close to the ground, ﬂapping slowly. The adult feeds on ﬂower nectar.
