small to medium-size: wingspan usually between 9 and 37 mm
Below is a guide to the local subfamilies of Pyralidae. The images included are meant to be illustrative of the general appearance of each subfamily as an aid for narrowing down possibilities for identification. While the commonest elements of forewing maculation in each subfamily are represented, many patterns are not.

Pyraloidea, the third largest superfamily of the Lepidoptera, is comprised of two families - Pyralidae and Crambidae. The history of families previously placed in the Pyraloidea is discussed. The group now includes about 16,000 species worldwide. Morphologically, the superfamily is defined by a basally scaled proboscis and the presence of abdominal tympanal organs. The larvae of many species are economically important pests of crops (e. g.: sugarcane, corn, rice), and stored products such as seeds and grains. Currently 22 subfamilies comprise the Pyraloidea; only the 19 subfamilies that occur in the Western Hemisphere are discussed. There is a paucity of recent research using cladistic methods and phylogenetic analyses across all taxa.
