Winter Wasp Blip

Working on the new room today we must have woken him up. We connected the old Jotul stove to the chimney albeit provisionally and were able to heat the room for the first time. The glorious warmth must have awoken our friend here. I think he's a wasp, but maybe I'm wrong? I heard him buzzing just as I was starting to despair about today's blip.

The room is visibly much closer to completion. The attention of the invisible pipe man is much called for. I wonder if he can hear?
