Psychidae

Overview

Australia is rich in primitive species, often with fully-winged females, sometimes referred to the Taleporiinae . They have relatively simple venation, with M usually present and often forked in the discal cell of both wings. The fore wings often lack one vein, and the tibial spurs are 0-2-4. The larvae feed on many angiosperms, but a few feed on gymnosperms, lichens, and mosses. Certain exotic species feed on dead insects.

Description

Small to medium-sized; head with roughened hairs; ocelli present or absent; antennae often bipectinate to apex; proboscis and maxillary palps rudimentary or absent; labial palps short or rudimentary, without lateral bristles; epiphysis usually present, sometimes very long; tibial spurs 0-2-4, 0-1-1 or absent; fore wing with M usually present in discal cell, often forked, chorda sometimes present; CuP usually separate or partly fused with 1A+2A or connected by a cross-vein; hind wing with M usually present in discal cell, sometimes forked, R 1 sometimes joining Rs and Sc, sometimes one or more short branches from Sc+R 1 to costa, CuP often present; females fully winged, brachypterous or apterous; abdomen in male often grossly extensible, in female with anal tuft of long hair. Larva case-bearing; case with anterior opening through which larva feeds, and posterior opening through which faecal pellets are ejected; crochets in lateral penellipse, uniordinal. Pupa with dorsal abdominal spines, in female eyes and appendages sometimes greatly reduced or absent; in larval case, partially protruded at ecdysis or, in females of some species, remaining in case.
