Over 60 species occur in Europe, a good many of them living as miners. The British species are treated by (2002c). Of importance here are the genera Cosmopterix and Pancalia.
Some Cosmopterix species mine in grasses, and can easily be confused with Elachista species (Elachistidae) that equally inhabit grasses. Cosmopterix larvae are widest in the abdominal segements and don’t have a chitinised plate between the front feet; Elachista larvae do have this plate, and are widest in the thorax.
