Zebra Swallowtail

The zebra swallowtail caterpillar primarily feeds on pawpaw trees (Asimina spp.). These trees are native to North America and provide the perfect habitat for both the caterpillar and the adult butterfly.

Spicebush Swallowtail

Eastern Tiger Swallowtail

The larvae of the Eastern tiger swallowtail (Papilio glaucus) feed on various tree species. Common host plants include ash (Fraxinus spp.), wild cherry (Prunus avium), and tulip tree (Liriodendron tulipifera). These trees are widespread across North America, providing ample resources for the caterpillars to thrive.

Black Swallowtail

The black swallowtail (Papilio polyxenes) caterpillar has a diverse range of host plants within the parsley family (Apiaceae). Popular choices include parsley (Petroselinum crispum), dill (Anethum graveolens), and fennel (Foeniculum vulgare). These plants are commonly found in gardens and provide the necessary nutrition for the caterpillar’s growth.
