Thank you Bcrazy, i know about the gorging with honey,and dancing bit,but still find it amazing how they can just forget where they came from when you may re-hive them right next to the hive they have come from,and yet they do not return.Not even the foragers,that have spent some time going to and fro from the original hive.It is amazing how they can just forget this,yet remember some flowers over a mile away,and keep going back.I wonder during this period of swarming if they also forget where they were last foraging.Also sometimes,a swarm that leaves a hive that has a clipped queen will cluster from anything like 20 mins to several hours,before they seem to realize the queen is not there,they have gone through all the above suggestions,yet they remember and return to the hive they have come from,minus the queen,which is usually lost in the grass.And they do not seem to find her,via pheremones,and the parent hive may only have Q cells, so no queen pheromone there.
