Supersedure

There's a honey flow on. All the hives in my out-apiary have stores now and there's a lot of activity. The bees are noticeably better tempered.

The roaring that I heard recently was probably the bees fanning, to cool the hive and evaporate excess water from the honey. I knocked on the side of A Hive this morning (the one which roared); they revved for a moment and then calmed down. Not queenless, just busy.

I looked into Hive B a few days ago and found no brood and no Queen. The colony is quite small so she probably wasn't hiding.

Is there a virgin Queen waiting to take over? That would be reasonable following the supersedure which I saw in progress at the start of the month. I will have to look again to see whether brood returns. What happens if the colony is unable to create a new Queen? I'm unsure.
