Numerous, see text Aglossa is a genus of small moths belonging to the family Pyralidae.

They are found mainly in western Eurasia, though some species have been introduced elsewhere.

[1] This genus is remarkable for the caterpillars, which in some species are able to feed on a wide range of materials that are not usually eaten by Lepidoptera larvae, such as dead insects, manure and straw.

The caterpillars of other Aglossa (e.g. A. signicostalis) are myrmecophilous.

[2] Adults of the grease moth (A. cuprina) sometimes eat fats such as suet.
