I don't think there is a perfect queen bee,most beekeepers look for the same traits,mild manners, fast build up in the spring, less swarming traits,and good honey producers. I have found over the many years the queens that build up fast, and on the hot side are the best honey producers and take less care from the beekeeper other than swarm prevention. The mean, fast build up,and quick to swarm, and will if not watched, tend to be my best hives for honey producers. They also seem to have less mite and disease problems. Jack
