It is the natural reproductive urge of honey bees to build up numbers in the Spring in order to swarm and establish new colonies. This activity has other benefits for bees besides the increasing of numbers—it helps bees cleanse their colonies of carpetbagging diseases and pests by initiating a break in the brood rearing cycle. Many pathogens depend on a continuous occupancy of the brood nest and young bees, so when the swarm leaves the hive and takes up to two weeks to find a suitable cavity, draw comb, and the queen commences egg laying, the pathogens drop away.
I have asked other beeks about their impression of swarming this year. Rob Stone with Orange County Beekeepers Club says not much swarming activity is being seen down South. Scott Davis in Palos Verdes has had half the number of swarm calls he would expect and thinks the issue is the prolonged drought.
So for the time being, the ongoing drought is affecting the forage sources of the bees such that fewer have the numbers to swarm successfully, are making less honey, and finding less pollen for raising brood.
