Something crept in…
and compromised the wasp nest. My last post showed adult paper wasps (Polistes metricus) evicting some of their young. The workers were clearing the nest of sick and poorly-developing larvae and pupae. A deadly agent had entered the nest. What was it? I had filmed eighty hours of surveillance video. Maybe I could figure that out.
My first clue was a scene that screamed foul play.
