Ribbed Cocoon-Making Moths

Bucculatricidae or (Bucculatrigidae) is a family of moths. This small family has representatives in all parts of the world. Some authors place the group as a subfamily of the family Lyonetiidae.

Adults of this family are easily overlooked, being very small with narrow wings wrapped around the body at rest. When small, the larvae are leaf-miners, forming distinctive brown blotches on leaves. When larger, they usually feed on the leaves externally. Many species have specific host plants. The pupal cases have distinctive longitudinal ridges, leading to members of the family commonly being called ribbed cocoon makers.

Some authors recognize just a single large genus, Bucculatrix, although two Australian genera, Cryphioxena and the scribbly gum moths (Ogmograptis spp.) are now sometimes placed in this family rather than in Elachistidae.
