A 6 yr study of natural swarming [of honeybees, Apis mellifera] in Ithaca, New York, USA, showed a bimodal distribution for date of swarm emergence, with a peak during the first 2 wk in June and a lesser peak during the last week in Aug. and the 1st wk in Sept. The mean swarm size for 126 swarms was 1.53 kg (11,800 bees). The mean wt of 116 swarm queens was 195.9 mg; of mated queens, 203.4 mg; and of virgin queens, 185.0 mg. Data from 1976 suggest that a virgin or a young mated queen may accompany a prime swarm.
