Lesser Mealworm

Alphitobius diaperinus

Lesser Mealworm

The adult beetle is common in poultry houses, stored grain areas, manure, and dry organic debris where it hides under litter or in narrow cracks. It scavenges on feed, fungi, droppings, carrion, and small soft-bodied material, becoming most active in dark, warm conditions. Though small, it has hard wing covers, can disperse by flight, and is notable for surviving in dense, disturbed farm environments where many predators and cleaners are absent.
