Zebra Swallowtail

The Zebra Swallowtail relies exclusively on pawpaw trees for its larval development, making the presence of these trees critical for the species' survival. Female butterflies lay their eggs specifically on the leaves of these North American understory trees.

These distinctive butterflies are commonly found in eastern North America, ranging from the southern parts of Canada down into Florida. They prefer wooded areas, riverside habitats, and moist environments where pawpaw trees naturally grow.

The prominent black and white stripes on the Zebra Swallowtail's wings serve as disruptive camouflage, breaking up the butterfly's outline when it is resting. This striking pattern also acts as a visual warning to birds and other predators that the butterfly may be unpalatable due to toxins absorbed from its pawpaw diet.

Yes, entomologists recognize a few different subspecies of the Zebra Swallowtail, such as the larger, more vibrant spring form. The summer forms tend to have shorter tails and darker wing markings, an adaptation to the hotter weather in their eastern North American range.
