We found this bug in our house upon returning from vacation. It was just lying on the floor in our family room. We were glad that it was already dead and we weren’t here when it entered. Neighbors have mentioned finding similar ones in the neighborhood, but no one seems to have seen them before this year. Seems to look like a lot of other beetles out there, but the tail stinger is throwing us off.
It seems like this year we have gotten a few more reports of Brown Prionids, Orthosoma brunneum, than we have in previous years, but mid summer is the peak time for sightings of this species and its relatives. What you have mistaken for a stinger is the ovipositor of the female, an organ used to lay eggs.
