Description of Mimallonidae
The Mimallonidae are the sole family of the Superfamily Mimallonoidea. They are primarily distributed in the New World tropics, with about 200 species described and 4 species found in North America. Mimallonid adults are medium to large, stout bodied, hairy moths with broad wings (wingspan 2-5 cm). Larvae are thick in the middle, tapering toward ends. Later stages build unique, open-ended cases or "sacks" of silk and leaves in which larvae overwinter. Pupation is in late spring.
