Small dark ground beetle (likely a seed-eating ground beetle)

Usually found outdoors under stones, leaf litter, logs, and around garden soil; some enter buildings accidentally, especially at night.

Adults commonly eat seeds, grains, and plant material; many related ground beetles also consume small insects and larvae.

Mostly nocturnal and fast-moving, often hiding during daylight. Adults overwinter in soil or sheltered places; identification to species requires a clearer view of body shape and markings.

Harmless to people, pets, buildings, and stored food in typical indoor encounters. Ground beetles generally benefit gardens by eating pest insects and weed seeds.
