"On the other side of the stud from the colony. I saw that in a cutout this year too. Is that evidence of a previous colony that failed? In my case, there were a few more pieces of really old comb, and residue on the inside wall showing where a colony used to be. Then on the other side of the stud, was a large colony like the one shown. I'm thinking the parent colony failed at some point in the past, but a swarm took up in the next section of wall, perhaps from the original.
What do you guys think? Is that what we see in this pic?Huh"
==============================================
Most likely, they started to expand into that area, but gave it up because of a too-narrow opening, or lack of ventilation. Or started during a heavy flow which came to an end and it was abandoned.
Just my $ 0.02, for what its worth..........
