So, last time I was worried about too much pollen... seams like they took care of that, lots more space for larva and lots of eggs and little ones.
Now, it would seam that the bees are opening up some of the drone brood. And possibly... eating it? (They have lots of pollen, about three bars of honey, and capped stores at the top of all brood bars.) It looked like they were trying to eat out of the roughly uncapped cells similar to the honey eating they do when you open them up.
Anyway, I had quite a few bars (top bar hive) and a few 'patches' with drone brood. It looks like the cap is being chewed off, and the little pupae exposed. Some of them I couldn't see more than white, but it sure seamed like some had eyes on them. Some of the surrounding capped cells were emerging. Perhaps these are in the process of being capped? (but since the neighboring cell is hatching, and in some cases I know the larva were about to be capped on the 14th
I plucked out some of the suspicious ones, and found no mites. I plucked a few randomly from the hive (no mites). I did spot one mite (suspect) on a little worker. Prior to this, no mites spotted. Is this mite an indication I should do a more extensive check for infestation.
I can't tell because many cells remain uncapped, but could it be that they are done making drones? and converting those cells to workers?
This only appears to be happening to the drone brood. The worker brood seams fine.
