Swirly butt bug

We’ve been trying for years to figure out what kind of bug this is. We call them swirly butt bugs because many of the ones we see look to have something protruding from their rear side that seems to move in a circular motion. I can’t tell from this picture if this one had it or not. We have to get them out of the house all the time, yet I don’t think I’ve ever seen one outside. Again, I can’t tell if it’s obvious from the picture, but he does fly. I don’t think they much care what season it is. Please tell me what kind of bug this is.

Ensign Wasp

Hi Brittany,
We just posted another identification request for the Ensign Wasp that has a much clearer photo than the one you submitted, but what we really like about your request is the colorful way you described the behavior of the Ensign Wasp.  It waves its abdomen about like a flag.  Ensign Wasps parasitize the ootheca or egg cases of cockroaches, and the increased number of reports we are receiving of Ensign Wasps spells bad news for cockroaches.
