Aaaah, the mystery of it. The theory of a super-organism probably plays a distinct role here. Bees are perceived to be only the cells of an organism, called - for want of a better term - the bee colony. As each cell in e.g. a human body is constantly replaced because of it's inherrent wear and tear, so each bee is replaced over time. As each cell or groups of cells have a function to perform in the body, so too does each bee or group of bees have their function to do in the colony. As humans and other creatures procreate, so too do colonies of bees procreate by casting swarms. The communication within human bodies is performed by hormones: so too does the colony have chemical signals coursing through it in the form of pheromones. In the event of DCA's it is perhaps slightly simpler - they are drawn by the queen pheromone towards a general area. There, perhaps survival instinct groups them together in "safer" areas, in clearings between trees, in valleys and other wind becalmed, open areas surrounded by shelter from predatory birds. We know that bees are attracted to the vibrations of other bees and that is perhaps the reason why they group together within DCA's. No need to be told by the previous "old-boys" of the club where the party is at. There have been many studies done on DCA's. Lately with radar. One of our SA researchers Geoff Tribe has done a lot of work on them. I you wish, I could request furher input from him. Greetings Robert Post
