Beetle ID? Wild, Maryland. Huge.

Well that has to be one of the most beetle looking beetles I’ve ever seen. I am going to say it is a Hister Beetle. Now Hister Beetles have 3,900 species and I don’t think I’m going to be able to get an exact species but it’s definitely in Histeridae.

Bit hard to judge size, how big roughly?

Looks about two to two and a half inches long to me.

@Westcoastperson - Hister Beetles are tiny.

@TinoPup - I can't really see much from the photo (it's too small), but have a look at photos of female Dynastes tityus and see if that looks right. They are typically pale brown with a sort of spotty-blotchy pattern but in high humidity they turn very dark brown (with the patterning still visible but indistinct).

@Chlidonias Think that's right : Female Rhinoceros Beetle? - Dynastes tityus

Yeah I would agree with female Dynastes tityus, looks pretty much identical to several photos of the species. Also aligns well with the apparent size and stated location.

@Chlidonias is right the body type and size for an eastern rhino beetle female fits much better than a Hister beetle my apologies.

Thanks everyone! That looks correct. I saw it again yesterday morning, it got stuck upside down on the stairs, so sent Argus a couple of better photos (including a size comparison with a Tide pen... couldn't find a darn thing in the basement that would work better for measurement )
