Once in a while, some of the bees in a hive need a little directional guidance from their sisters. Individual bees can get lost or confused as to where the entrance of the hive is or where they should be. No problem, that’s when some of the more alert bees take charge and put out the call to round up the hive and bring the group back together again.
When we humans want to round up friends from a distance we typically use sight or sound (or more frequently phone calls or text messages.) When bees call each other from a distance, they use none of these. The bees’ method of communication is a method that we would never think to use; they release a pheromone that signals the other bees to come together via the bees’ powerful sense of smell.
This pheromone is called the Nasonov pheromone. Bees produce this from the tip of their abdomens. When they wish to release the pheromone, they raise their abdomens and fan their wings vigorously, broadcasting the scent as far as they can. It is not uncommon for a beekeeper working with a beehive to see some bees around the edge of the hive releasing this pheromone.
Often, the very act of the beekeeper opening the colony can disorient some of the bees, especially the foragers who are returning with nectar and pollen. Fortunately, the Nasonov pheromone is a powerful call that brings the bees back home.
Beekeepers will also notice this activity when watching a swarm that has decided to settle in a particular spot. At the edge of most swarms, a few bees can always be seen frantically calling their sisters to the chosen spot, and gathering the hive together once again.
