Why do #honeybees swarm? Because they are honeybees. Honeybees swarm for a number of different reasons, but the overwhelming most reliable reason why honeybees swarm is due to genetics. Genetics make honeybees swarm and it is also one of the primary ways that honeybees expand the population and genetic diversity of colonies in a geographic area. Honeybees can also swarm due to inhospitable living conditions such as, too crowded and not enough space, poor beekeeping skills (i.e. the beekeeper is new or not paying close enough attention), and pest infestation. Even though a swarm of honeybees looks very threatening, it is my experience that while honeybees are swarming, they pose little of no risk to people. Prior to an actual swarm, a pheromone based signal is given off, likely from the Queen, to prepare for swarming which causes many actions to start happening. Some of which are: scout bees go out and find a new suitable home and report back and the nurse bees build a queen-rearing honey-comb cell for a new future queen. Once the queen-rearing honeycomb cell is built, the existing senior queen deposits a fertilized egg inside. About twenty-eight days later a new and future queen bee emerges, soon thereafter, she takes a mating flight and the male bees all chase her, where I have read, a queen bee will mate with as many male bees as she can, sometimes over fifty!
Once the new and future queen returns from her mating flight, the existing senior queen has decided to leave, relinquishing the hive to the new and future queen. The senior queen already has made a crucial decision of where the next home will be and then she takes roughly 50% of the worker honeybees with her and by the tens of thousands, they take flight. Presto! You have a swarm of #honey #bees.
Over the next couple of weeks to two months, I will be out capturing honeybee swarms, where and when possible, I will post pictures of the little darlings wherever they land a give you all an update of honeybee hijinks.
