Re: Signs of swarm preparation?
I know in my hive they may have placed the nectar above the nest. but they did not put it at the tip of the hive. they worked there way up.
Since last year i have seen some things that make me wonder if i should not have kept more empty space just above the brood nest though. as the bees worked there way up they built a longer and longer band of solid honey or nectar between the main nest and where they where storing nectar. Keep in mind the brood nest stretched up through this space as well.
With all the discussion about side expansion this past year. I have been playing over in my mind some ideas that are a variation of both checkerboard and continued side expansion of the brood nest. Mainly my thinking centers around more attention being given to keepign empty space near the brood nest where ever it is. I imagine it might keep the bees aware that more building is still necessary. Just one more detail that may help keep the bees in the fill it up mode rather than the pack it up mode.
At one time I read a comment that directly claimed that one of the unique qualities of the Langstroth hives. is that for unknown reasons it will cause bees to work upward. In fact they tend to move upward rather than down when given the choice. I have seen this myself. Interesting little tid bit if nothing else.
