Angoumois grain moths are small, tan moths that reach about 1/2 inch long as adults, who are easy to distinguish from other moths by their fringed hindwings. These moths are serious pests of corn and other whole grains. Their lifecycle often begins in corn fields, where females carefully lay one egg per kernel on developing corn. When larvae hatch in about a week, they burrow into the corn kernel and begin to feed. After 25 to 64 days, the cream-colored, legless larvae mature after pupating inside the corn kernel and emerge to start the cycle all over again.
