Ground beetle (likely a black ground beetle)

Usually found under stones, logs, leaf litter, and in soil, gardens, or woodland edges. Adults may wander indoors, especially at night or during wet weather.

Mostly predatory, eating caterpillars, beetle larvae, slugs, snails, and other small invertebrates; some species also consume seeds or plant matter.

Generally nocturnal, fast-running, and flight-capable, though many rarely fly. Adults overwinter in sheltered places; larvae develop in soil or leaf litter.

Harmless to people and household structures, though it may release an unpleasant defensive odor or nip if handled. Beneficial predators that help control garden pests.
