Hi all, Somthing that occurs to me about the holes in comb is that I think they occur pretty frequently in frames in hives, but much less so in wild comb. I wonder if the trigger for building the holes is therefore the obstruction caused by the frame itself, maybe agravated by the desire to build queen cells on the edges of the comb. I notice that queens do seem more often than not to use the holes to get from one side of the comb to the other -- maybe queens don't as a rule like leaving the wax to move around.
