Eriocottidae

Definition

A family of small moths in the order Lepidoptera, commonly known as Old World spiny-winged moths, placed in the superfamily Tineoidea with uncertain relationships to other tineoid families. The family comprises two subfamilies, Compsocteninae and Eriocottinae, and is distributed primarily in the Old World tropics and subtropics. Adults typically exhibit reduced wing venation and males often possess modified, scale-covered hind legs; larvae are concealed feeders in leaf litter, decaying wood, or fungal fruiting bodies.

Etymology

From Greek erion (wool) + kottos (a fish of uncertain identity, here used in the sense of 'spiny' or 'rough'), referring to the scale-covered or spiny wing appearance of adults.

Example

Species of Eriocottidae such as those in the genus Compsoctena are frequently encountered in tropical leaf-litter samples and are distinguished from similar tineoid moths by their characteristic wing scaling and reduced wing-coupling apparatus.

• concealed larva

Usage Notes

The family's placement within Tineoidea remains unresolved; some molecular studies suggest potential sister-group relationships with Psychidae or other tineoid lineages. Eriocottidae are not to be confused with the New World family Arrhenophanidae, which shares superficial morphological similarities but belongs to a different superfamily (Gelechioidea). The subfamily Compsocteninae was historically treated as a separate family, and literature prior to ~2010 may use 'Compsoctenidae' for this group.
