Attevidae

Definition

A monotypic family of small moths in the order Lepidoptera, containing only the genus Atteva. Members are characterized by bright aposematic coloration—typically orange, red, or yellow banding against black or white—and a pantropical distribution, with some species extending into temperate regions. The family's phylogenetic placement remains unresolved, though most authorities place it within the superfamily Yponomeutoidea (ermine moths and allies).

Etymology

From the type genus Atteva + Latin suffix -idae (family rank).

Example

The ailanthus webworm moth, Atteva aurea, is the most familiar North American representative of Attevidae; its larvae construct communal silk webs on host plants in the Simaroubaceae family.

Usage Notes

Attevidae was historically treated as a subfamily (Attevinae) within the family Yponomeutidae, but molecular and morphological studies support its elevation to family rank. The family is notable for its specialized larval biology: caterpillars are web-forming folivores typically associated with Simaroubaceae (quassia family) plants. Taxonomic stability is complicated by the group's small size and the paucity of phylogenetic studies explicitly sampling Attevidae.
