Natural Habitat

Typically found indoors in kitchens, pantries, food processing plants, and grocery stores where dried goods are stored.

Diet & Feeding

Larvae feed on stored grains, cereals, nuts, dried fruits, flour, spices, birdseed, and dry pet food. Adults generally do not feed.

Behavior Patterns

Adults fly in a zigzag pattern and are attracted to light, usually active at dusk or night. The distinctive wing pattern features a reddish-brown or copper lower half and a grey/tan upper half. Larvae leave silk webbing in food products.

Risks & Benefits

No physical harm to humans (they do not bite or sting). Their primary risk is economic and nuisance as a major pantry pest, contaminating food with webbing, frass (droppings), and cast skins.
