Orgyia Ochsenheimer, 1810
This genus of tussock moths contains around 40 species. They are widely distributed and feed on various trees and shrubs. Several species are important pests, causing significant damage to forest trees or attacking crops like coffee, cacao, rubber or fruit trees. They can cause periodical outbreaks. Examples of pests are the Douglas-fir tussock moth, Orgyia pseudotsugata, and the whitemarked tussock moth, Orgyia leucostigma.
Compared to related genera, species of Orgyia are small with a wingspan of typically 2-4 cm in males. Males hold their first pair of legs in an outstretched position when at rest. Females are usually flightless. The larvae typically grow to a length of up to 3-4 cm and are often strikingly coloured.
