Description The (Eastern) Black Swallowtail (Papilio polyxenes) also called the American Swallowtail or Parsnip Swallowtail, is a butterfly found throughout much of North America.

A male of this species has a yellow band near edge of wings; a female has row of yellow spots. The hindwing of the female has an iridescent blue band.
