Quick Summary

The Papilionidae family, commonly known as swallowtail butterflies, are a group of butterflies found worldwide, excluding the Arctic. They are characterized by the distinctive tail-like extensions on their hindwings, though some species lack these.1

Key features of this family include:
* Appearance: Many species display vibrant yellow, orange, red, green, or blue markings against a black, blue, or green iridescent background. Coloration can vary between sexes and seasons. Some swallowtails mimic the patterns of toxic butterflies for protection.1
* Larvae: The brightly colored larvae feed on foliage. Some have eye-like spots on their thorax that resemble a snake's head, and others are camouflaged to look like bird droppings. When disturbed, they can emit a foul-smelling substance.1
* Pupae: Unlike most butterflies, parnassians (a subfamily within Papilionidae) pupate inside cocoon-like webs. Other members of the family pupate without cocoons, with their chrysalis hanging from a silk pad or supported by a silk girdle.23

The family Papilionidae is part of the larger superfamily Papilionoidea.4
