LYMANTRIIDAE Tussock moths comprise mainly medium-sized species to large moths that have very furry bodies and extremely feathery antennae in the males. Their overall shape is similar to that of the noctuids. The females in the genus Orgyia (vapourers) are flightless and in the gypsy moth the female, though fully winged, is incapable of flight. In most species the haustellum is rudimentary and non-functional. The larvae of all species are adorned with tufts of brightly coloured hairs which often cause severe irritation if the larvae are handled. The larva of one species, the brown-tail, is a pest, defoliating its foodplants and eliminating other species of Lepidoptera which are in competition with it Most species are polyphagous or oligophagous on trees, shrubs or heathers. The majority hibernate as larvae but 81
