Darkling beetle (likely a mealworm beetle)

Stored grains, flour, cereals, animal-feed areas, and occasionally homes. Adults often hide in dark, dry crevices.

Larvae and adults consume grains, bran, flour, and other decaying plant material; adults may scavenge household food residues.

Mostly nocturnal and capable of flight, though they commonly crawl and hide when disturbed. The life cycle includes egg, mealworm larva, pupa, and adult stages.

Generally harmless to people and pets, though infestations can contaminate stored food. They help decompose organic material and are widely used as feeder insects.
