Tineidae is a family of moths in the order Lepidoptera. Collectively, they are known as fungus moths or tineid moths. The family contains considerably more than 3,000 species in over 300 genera. Most of the tineid moths are small or medium-sized, with wings held roofwise over the body at rest. They are particularly common in the Palaearctic, but many occur elsewhere, and some are found very widely as introduced species.
Tineids are unusual among Lepidoptera as the larvae of only a very small number of species feed on living plants, the majority feeding on fungi, lichens and detritus. The most familiar members of the family are the clothes moths, which have adapted to feeding on stored fabrics. The most widespread such species are the common clothes moth (Tineola bisselliella), the case-bearing clothes moth (Tinea pellionella) and the carpet moth (Trichophaga tapetzella); the brown-dotted clothes moth (Niditinea fuscella) despite its name preferentially feeds on feathers in bird nests.
