The Lymantriidae, the tussock moths, are a family of moths that usually lack a proboscis as adults; the larvae often feed on trees.

Characters (from Nielsen & Common 1991): Small to large; ocelli absent; antennae bipectinate to tip in male and usually in female, usually with one to three long terminal setae on each antennal branch; proboscis usually absent; maxillary palps 1-segmented or absent; epiphysis present in male, reduced or absent in female, tibial spurs short, 0-2-4, rarely 0-2-2; females sometimes brachypterous, flightless; fore wing often with areole, R3 and R4 stalked from discal cell or areole, 1A+2A simple; hind wing with Sc diverging from Rs at base but approximated to, and usually connected with, Rs by R1 towards middle of discal cell, rarely fusing with Rs for short distance, Rs and M1 usually stalked, M2 arising nearer to M3 than to M1; thorax and abdomen densely hairy; abdomen with counter-tympanal hood prespiracular, abdominal segment 4 usually with pair of pockets, in female with dense anal tuft. Egg often hemispherical, rounded or subcylindrical, laid in cluster, usually covered in hair-scales from anal tuft. Larva with densely tufted secondary setae, often with four long dense dorsal tufts or with hair-pencils, a coloured dorsal gland on abdominal segment 6 and usually also on 7; external feeders, often arboreal. Pupa stout, hairy, in silken cocoon incorporating larval hairs.
