Re: No queen, no cells
The short version of one scenario is you missed a couple supersedure cells, that's not meant as a negative comment. If bees are not removed from the comb and each frame looked at very thoroughly, it's easy to miss QCs. Particularly, if the bees only put a couple supersedure cells on the lower edges of a partially drawn frames, easy to miss even when you're looking for them. Not the level of detail I conduct for a normal "healthy hive" inspection.
The other scenario is queens and QCs use Klingon Cloaking Technology, only valid explanation on how some queens can be missed on more than one pass through a hive.
