25-5-2015 GENOVES, VALENCIA - OLD WORLD SWALLOWTAIL BUTTERFLY (Papilio machaon)

Papilio machaon, the Old World swallowtail, is a butterfly of the family Papilionidae. The butterfly is also known as the common yellow swallowtail or simply the swallowtail (a common name applied to all members of the family, but this species was the first to be given the name). It is the type species of the genus Papilio. This widespread species is found in much of the Palearctic (it is the only swallowtail in most of Europe) and in North America.

This species is named after Machaon (Ancient Greek: Μαχάων, romanized: Makháōn) a figure in Greek mythology. He was a son of Asclepius.

Papilio machaon was named by Carl Linnaeus in the 10th edition of Systema Naturae in 1758, alongside nearly 200 other species of butterfly. Later, Pierre André Latreille designated it as the type species of the genus Papilio. The specific epithet machaon refers to Machaon, son of Asclepius in the works of Homer.
