Moth larvae can infest a wide range of dry foodstuffs of vegetable origin, such as cereal, bread, pasta, rice, spices or dried fruits and nuts. The food they infest will often seem to be webbed together. After larvae or moths have been found, it is important to throw out all food sources that are not in very tightly sealed containers. The moths are able to get into surprisingly tight spots, including sealed bags and Tupperware containers. They are also notoriously difficult to get rid of, and can crawl on ceilings and spin cocoons in rooms other than the kitchen or pantry where they hatched. The larvae are able to travel significant distances before they pupate. When seeking the source of an infestation, the search thus cannot be limited to the immediate area where pupae are discovered.
Adults are 3/8 inches in length with up to 3/4 inch wingspans. The outer half of their forewings are bronze, copper, or dark gray in color, while the upper half are yellowish-gray, with a dark band at the intersection between the two. The moth larvae are off-white with brown heads.
The entire life cycle of this species may take 30 to 300 days. Female moths lay between 60 and 400 eggs on a food surface and not sticky. The eggs hatch in 2 to 14 days. The larval stage lasts from 2 to 41 weeks, depending on the temperature.
