Swallowtail Butterfly Pictures

The family Papilionidae, better known as Parnassian and Swallowtail butterflies, are large butterflies, characterized by extended tail-like appendages at the bottom of their wings.

Five Parnassian (Parnassiinae) species and approximately forty Swallowtail (Papilioninae) species can be found in the United States. Almost two-thirds of the swallowtail species belong to the Papilio genus.

Finding swallowtails can be an easy task in the southern most areas of the United States. Close to one-half of all swallowtail species can be found, sometimes only occasionally, in South Texas and South Florida.

The remaining swallowtail species also have a limited geographical range, and therefore the number of species present in any area usually counts less than ten.

The links in the box point to pictures and descriptions of a representative sample of species.
