Re: What Happened to My Bees???
Was the hive strong then suddenly dwindled down to no one home? Could be CCD. Since this happen in the spring they could have gone queenless and just dwindled down to the point that they could not maintain the hive. The comb looks clean with pollen so they should not have absconded because of undesirable conditions. The white stuff could be mold. I don’t notice any capped honey so they were probably robbed out by other bees. Two years ago I had several hives that did the same thing in August. I scarped the foundation, not giving it back to other hives, have not had a repeat.
The Busy Bee teaches two lessons: One is not to be idle and the other is not to get stung.
