I found the insect in the pictures on the floor of my kitchen this evening. From the research I’ve done, I am leaning towards some variety of stag beetle. Most of the descriptions I’ve found include black as a possible stag beetle color, but the only pictures I’ve found are for those with giant mandibles like the UK variants.
I’m hoping you can confirm it’s an innocent but misplaced stag beetle that wandered inside, and not some vicious, infectious pest, as my bug-a-phobic mind always assumes.
Though it resembles a Stag Beetle, this is actually a Big Headed Ground Beetle, Scarites subterraneus, or another member of the genus. This is a beneficial, predatory species and it will not cause any problems for your home or its inhabitants. You can find additional information on BugGuide where it states: “adults are nocturnal predators on other insects.”
