looked in my main colony which swarmed and then settled down to raise a virgin queen on 11th May. About 10 days ago there were 2 frames of eggs and larvae - hooray I thought.
When I looked this afternoon, they were starting to put stores in the second super, capping some of the first super but blow me down, I found 4 capped supercedure cells and a swarm cell, the last on the side of the frame. A queen had laid eggs in 3 frames, there was a frame of capped brood and a mix of young to older larvae in all 5 frames. Her maj was nowhere to be seen, mind you apart from pulling her out of a cell on 11th May I haven't see her since and it might not have been the same queen doing all this laying.
Clearly they haven't put aside all swarming instincts then!
