The Tineidae are a fairly large family of the Superfamily Tineoidea. These are small to medium-sized moths with wingspans of 0.7-3.6 cm. Adults of most species are dark in color, and most have very rough head scales. Some are important pest species, and these are typically pale, with or without markings. These moths typically have wings that are broadly lancelike and somewhat rounded at the tips. In most genera, the venation is complete. Larvae eat a variety of food including dead plant and animal matter, fungi, wool, and similar materials. Most larvae form cases similar to those of casebearers. Acrolophus species feed on roots of grasses and form silken tunnels among them.
