Honey bees utilize specific wing motions as a vital component of a complex, flow-mediated communication strategy known as scenting. This behavior is crucial for coordinated activities, such as guiding a swarm to a new hive site or helping bees locate the queen.
Scenting Behavior: When a bee detects a pheromone signal (like the queen’s or the Nasonov pheromone), it will extend its abdomen to expose a pheromone gland and then fan its wings vigorously.
Directional Airflow: This wing fanning is not just ventilation; it creates a directional airflow that actively advects (transports) the chemical signal away from the emitting bee. This turns the typically non-directional chemical diffusion into a directional signal.
Communication Network: This directional signaling allows individual bees to “rebroadcast” the pheromone, forming a dynamic, collective communication network. This amplifies the chemical signal, allowing it to travel distances far greater than the reach of a single bee’s pheromone plume, effectively directing the rest of the swarm.
