The moths are small, with the forewing ranging in size from 2.5 mm to 5.5 mm, and at rest they are held at a steep angle, tent-like over the body. Members of the family to which this genus belongs are unique among the Lepidoptera in having chewing mouthparts rather than a
proboscis. They are often seen feeding, often in large aggregations, on the pollen of the flowers of many herbaceous plants, shrubs and trees. Eggs are
translucent white and laid amongst vegetation on the surface of the soil. For many species the pupa is unknown, but of those found it is within a tough silken cocoon.Mandibles developed. No tongue. Labial palpi obsolete. Posterior tibiae with spurs placed in groups of bristles. Forewings: vein 7 to costa, vein 11 connected by bar with vein 12, 12 giving rise to an additional vein (13) about middle. Hindwings as forewings, but vein 13 usually absent. == Species ==
