Some experts have included genus Acrolophus and Amydria here, while others have erected a separate family, Acrolophidae, for those genera. We are following the latter scheme.
Larvae feed on a variety of plant and animal matter, including for example fungi, stored grains, and wool clothing.
Adults have wingspans ranging from 7 to 36 mm. In most species the head scales are very rough. The labial palps "almost always have stout hairs projecting from the 2nd segment" (Covell, 2005).
