(subclass Pterygota, order Lepidoptera)
Family of small, primitive, drab or metallic moths. The antennae are very long in some species. The ovipositor is extensible and used to lay eggs in leaves or stems. Larvae are leaf-miners or stem-borers, or live in galls or among detritus. Frequently they construct cases from leaf-litter or from excisions from leaves. They have a wide distribution.
