Hi Guys, >Perhaps Dennis can say whether he put regressed bees in his TBHs... Yes I did. And I was quite surprised by what I found. My small cell bees didn't have any cell size memory at all. As a matter of fact, they only built large cell size comb. It was the bees that hatched out of that same large cell size comb, that later, drew out the small cell size comb in my tbh. Kind of a double blind test run by the bees themselves:>))) And I put some regressed small cell bees into standard hives with exclusively clean, large cell size comb. These hives were maintained for three seasons. And then some of these resulting large cell bees were again placed into a tbh. The results: They built a broodnest with the same orientation and cell size distribution as did the original small cell bees when put into a tbh.
