Black Swallowtail
(Adopted 1996)

This is the most widespread swallowtail, ranging from coast to coast and from the South southern Canada. There are 4 other less common but similar swallowtails. Both sexes are mainly black, but males have a narrow yellow band on both wings. Females usually lack the yellow band but have an iridescent blue band on each hindwing. The butterflies fly in open areas, including vacant lots, neglected areas, and gardens. If you grow parsley, carrots, or dill, the odds are that you will find Black Swallowtail caterpillars in your garden. Nectar flowers include butterfly milkweed, thistles, and red clover.
