Confused Flour Beetle
Tribolium confusumAlso known as Flour Beetle
Confused flour beetles thrive in pantries and commercial grain stores across the globe, feeding on finely ground starches, cereals, and dried spices. Named for the difficulty in distinguishing them from the closely related red flour beetle, these small reddish-brown insects rely on potent chemical secretions called quinones to deter competitors. Females lay hundreds of sticky eggs directly into food supplies, where larvae hatch to feed and pupate within the grain dust.
