I wonder whether somebody experienced with comb in feral bees can comment on whether they build a different size of cell in the broodnest area than they do elsewhere? I possess at this time two hives which contain all natural comb. These have top bars but no foundation. The comb is predominantly worker comb with drone combs built later at the bottom and edges of the large expanse of worker comb. At some point we intend to measure the proportion of drone to worker. There may be a very small amount of transition comb, but the notion that there are three cell sizes: worker, small worker, and drone, strikes me as erroneous. pb
