Epicopeiidae

Definition

A family of moths in the order Lepidoptera, commonly called oriental swallowtail moths for their striking resemblance to swallowtail butterflies (Papilionidae). Members exhibit exceptional morphological diversity in body size and wing shape, and participate in complex Müllerian and Batesian mimicry rings involving butterflies and other moths.

Etymology

From the type genus Epicopeia + -idae (family suffix)

Example

Species in Epicopeiidae such as Epicopeia mencia achieve effective protection from predators through visual mimicry of unpalatable papilionid butterflies like Atrophaneura alcinous.

Synonyms

• oriental swallowtail moths

Related Terms

• Lepidoptera
• mimicry
• Papilionidae
• Müllerian mimicry
• Batesian mimicry
• Drepanidae
• Uraniidae

Usage Notes

Formerly treated as a subfamily of Drepanidae or Uraniidae in some classifications; now widely recognized as a distinct family. The common name 'oriental swallowtail moths' refers to their geographic distribution (East Asia) and convergent wing morphology, not phylogenetic relationship to swallowtail butterflies. Wing patterns are sexually dimorphic in some species and function in both predator deterrence and mate recognition.
