The weird way bees use pheromones

Key Concepts

• Pheromones: Chemical signals used by bees for communication, varying based on situation (queen recognition, alarm).
• Fanning Behavior: A bee behavior involving wing fanning to disperse pheromones, signaling direction to other bees.
• Waggle Dance: A complex bee dance communicating the precise location (coordinates) of food sources or potential new hive locations.
• Scout Bees: Bees responsible for finding new food sources and potential hive locations.
• Forager Bees: Bees that collect pollen and nectar, guided by scout bee communication.

Pheromonal Communication in Bees

Bees utilize a sophisticated chemical communication system based on pheromones. These pheromones aren’t a single scent, but rather a variety of smells associated with different contexts. Specifically, bees possess a pheromone that identifies the queen, allowing colony members to recognize her presence and maintain social order. Crucially, they also emit an “alerting pheromone” when perceiving a threat or disturbance. While subjective, many beekeepers report this alerting pheromone smells like bananas, though this perception isn’t universal.

The video highlights fanning behavior as a key method of pheromone dispersal. When a bee engages in fanning – rapidly moving her wings – she actively releases pheromones into the air. This signals other worker bees, guiding them towards the source of the pheromone, which could indicate a point of interest or danger. The example shown in the video demonstrates a bee actively exhibiting fanning behavior, effectively broadcasting a chemical signal to incoming foragers.

The Waggle Dance: Precise Location Communication

Beyond pheromones, bees employ the “waggle dance” for communicating detailed spatial information. This dance is performed by scout bees after they’ve located a valuable food source (pollen, nectar) or identified a potential new hive location, particularly during swarming. The waggle dance isn’t random; it conveys the exact coordinates of the discovered location.

The process unfolds as follows: a scout bee returns to the hive and performs the waggle dance, attracting the attention of forager bees. She repeats the dance multiple times, allowing the foragers to interpret the information. Upon understanding the dance, the forager bees then depart to locate the indicated resource. The video emphasizes the efficiency of this system – the scout bee dances, and the foragers immediately head to the food source.

Interconnectedness of Communication Methods

The video demonstrates that pheromonal communication and the waggle dance aren’t isolated methods. Pheromones, like those released during fanning behavior, likely play a role in attracting attention to the dancing scout bee, enhancing the effectiveness of the waggle dance. The combination of chemical signals and the physical dance creates a robust and precise communication system.

Significance and Observation

The director’s off-camera remarks ("That's so crazy. That's insanely cool.") underscore the remarkable complexity and efficiency of bee communication. The ability of these insects to convey precise location data through a dance is a testament to the power of natural selection and the intricate social structures within bee colonies.
