The primary method by which bees communicate is through the use of pheromones and the "waggle dance." Pheromones are chemical signals that convey information about the environment, such as food sources or threats, to other bees. The waggle dance, performed by forager bees, consists of a series of movements that indicate the direction and distance of a food source from the hive. This unique method allows bees to efficiently share vital information, enhancing their collective foraging success and overall colony health.
