Indianmeal moth
Plodia interpunctella
- Order & Family
- Lepidoptera; Pyralidae
- Size
- Adults have a wingspan of about 14–20 mm (0.55–0.8 in) and are roughly 8–10 mm long at rest.
Natural Habitat
Common indoors near stored dry foods, pantries, kitchens, and food-processing areas; adults may rest on walls and doorframes.
Diet & Feeding
Larvae feed on grains, flour, cereals, nuts, dried fruit, pet food, seeds, and other dry goods. Adults do not feed and mainly reproduce.
Behavior Patterns
Adults are mostly nocturnal and weak fliers; females lay eggs near food, and larvae leave infested packages to pupate in cracks, corners, or ceilings. The reddish-brown and gray wing pattern is characteristic.
Risks & Benefits
They are harmless to people but contaminate stored food with webbing, frass, and cast skins. They provide minor food for predators but are primarily considered a household pantry pest.
