Medium-sized moths with rather long, narrow wings. They are plainly coloured and were described by Meyrick (1928) as "decidedly the least attractive family of the Microlepidoptera". The larvae will eat almost anything, including fresh and decaying leaves, seeds, berries, stored products, dead insects and bird-droppings. All the four species on the British list are adventive but two of them have become firmly established and both these occur commonly in Essex except, apparently, in the north-west.
