She looks good.
My guess is part of a drone.Curious though what do we call the white thingy sticking out of her butt after the flight?
Through subsequent pressure the bow of the bulb and chitinized plates, the "mating sign," detaches from the endophallus of the drone and remains inside the queen (Woyke and Ruttner 1958).
