Zebra Swallowtail, Eurytides marcellus

Zebra Swallowtail

Eurytides marcellus

Above: White with black stripes, triangular wings, and a long tail. The sexes are nearly alike. Below: Similar to the top but with a red stripe bordered by black on the hindwing.

Open, brushy woodland areas where Pawpaw grows.

Overwintering Strategy:   Chrysalis

Two generations in northern Illinois: early May and then June/July. Ebner (1970) states that the best time to look for them in Wisconsin is June and early July.

Caterpillar Host Plants:
Pawpaw (Asimina triloba)

The Zebra Swallowtail is an uncommon stray in Wisconsin, and may be looked for in the southern counties. Its larval food is the Pawpaw (Asimina triloba), which is not native to Wisconsin.

Overwintering Strategy

Two-way migration: Adult migrates from Wisconsin to Central Mexico
Small migration: Adult migrates from Wisconsin to southern US
Immigrant: Adult migrates into Wisconsin from warmer areas and don't fly south in winter
Adult Butterfly: Hibernates overwinter as an adult butterfly
Eggs: Eggs laid on stems, twigs or foot plants overwinter in diapause
Caterpillar: Caterpillars make nests on the base of plants and hibernate until spring
Chrysalis: Caterpillars shed their last skin, form a chrysalis and enter diapause.
