What is "papilio polyxenes"

Papilio \Pa*pil"i*o\, peop. n. [L., a butterfly.] (Zo["o]l.) A genus of butterflies.

Note: Formerly it included numerous species which are now placed in other genera. By many writers it is now restricted to the swallow-tailed butterflies, like Papilio polyxenes, syn. Papilio asterias, and related species.

The (Eastern) Black Swallowtail (Papilio polyxenes), also called the American Swallowtail or Parsnip Swallowtail, is a butterfly found throughout much of North America. It is the state butterfly of Oklahoma and New Jersey. An extremely similar-appearing species, Papilio joanae, occurs in the Ozark Mountains region, but it appears to be closely related to Papilio machaon, rather than P. polyxenes. 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.

The Papilio polyxenes demonstrates polyandry and a lek mating system, showing no male parental care and display sites. Females are therefore able to choose males based on these sites and males are the only resource the females find at these sites.
