Found overwintering under bark, wood chunks, grass clippings or leaf pile between Christmas Day and Dec. 30, I forget where now or exactly when.
This is one of several brownish similar-looking species that I have kept in a container loaded with rolled oats plus some puppy chow, dried shrimp fishfood, pieces of vegetable and fungus, some paper towel scaps to climb on and under, and a plastic waterbottle cap in which I keep a wad of tissue soaking in water. (The beetles use this watering station.)
I shot a bunch of these beetles earlier but between dorsal and ventral views I was unable to tell where one beetle's pix ended and the next began. I fixed this by shooting a small "New Specimen" sign between beetles.
This individual is *very* hirsute, and I think that may be an important factor in determining its species, at least judging by similar-looking Blaptinus images on this site
