"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..........
