The Momphid moths are small to very small in size, with a wingspan of 0.8-1.6 cm. They are very similar in appearance to blastobasid moths and elachistid moths. Little is known about many of these species. In species for which life histories are known, momphid caterpillars feed in buds and seed capsules of evening-primroses and related plants. Alternatively, blastobasid larva feed on dead leaves or fallen nuts, and elachistid larvae mine leaves of grasses and sedges.
