Darkling beetle

Found in many terrestrial habitats, including dry soils, leaf litter, under bark, and stored grain; exact habitat depends on species.

Varies by species; many feed on decaying plant material, fungi, seeds, or stored food, while some prey on small invertebrates.

Usually ground-dwelling and most active at night. Adults have hardened wing covers; larvae are commonly called mealworms or false wireworms.

Generally harmless to people and useful as decomposers, though some species damage stored foods or crops.
