27 species. Wingspan 10-28mm.
The Clothes Moth family. Their larva feed in a silken tube or from a flat silken case on fabrics and stored products mainly of animal origin, in the nests of birds, mammals and Hymenoptera on decaying organic matter, in fungi, and in dead wood probably mostly on fungal hyphae. 2 species feed on the sporangia of ferns and 1 species on lichen.
Imagines often run fast over surfaces spinning rapidly around. Formerly some were serious pests of woollen fabric and furs and feathers indoors and others in unheated buildings. Modern insecticides, the vacuum cleaner, and the more dry sterile modern domestic environments have caused some species to become extinct and others very uncommon and rare. Other species which live outdoors in natural habitats are still widespread in occurrence.
