The hind wings have a distinctly pointed appearance. These moths often are confused with clothes moths. The main difference is that they may fly around the house, while clothes moths shun light and usually are seen only in closets. Popcorn is a common host. Eggs may be laid on popcorn in the field or, more frequently, in storage.
Developmental time is about five weeks.
They are pale gray or yellowish white, wingless, soft-bodied louselike insects with poorly developed eyes and long, slender antennae. They often are found with food products stored under moist conditions. Actual damage to the food products is hardly detectable. They are pests primarily by their presence, thus the contamination of the food product. Developmental time is about three weeks.
