Papilio polyxenes, the (eastern) black swallowtail, American swallowtail or parsnip swallowtail,is a butterfly found throughout much of North America. It is the state butterfly of Oklahoma and New Jersey. The species is named after the figure in Greek mythology, Polyxena (pron.: /pəˈlɪksɨnə/; Greek: Πολυξένη), who was the youngest daughter of King Priam of Troy. Its caterpillar is called the parsley worm because the caterpillar feeds on parsley.
