A worker bee finds a patch of flowers producing plenty of nectar. She collects what she can carry and returns to the hive. But how do other workers learn where that food is located? Honey bees have developed a remarkable way of communicating information about food sources through movement. It is called the waggle dance. When a forager returns from a productive food source, she may begin moving across the surface of the comb in a repeated pattern resembling a figure eight. The important part occurs during a relatively straight movement called the waggle run. As she moves forward, she rapidly shakes her abdomen from side to side. She then circles back to her starting point and repeats the movement. This dance communicates two important pieces of information. Distance: The duration of the waggle run corresponds approximately to how far the resource is from the hive. Longer waggle runs generally indicate greater distances. Direction: The angle of the waggle run communicates the direction of the resource relative to the sun. On a vertical comb, a waggle run directed straight upward represents a resource in the direction of the sun. A run angled to one side represents a corresponding angle away from the sun. Other workers follow the dancer, sensing her movements and vibrations. Not every bee that follows a dance visits the advertised location. The dance provides information that workers can use rather than instructions they must follow. This behavior allows information discovered by an individual forager to influence the activities of other workers. But the sun continues moving across the sky while the flowers remain in the same location. How does a bee keep communicating the correct direction to a food source as the sun's position changes throughout the day? What did you learn about the waggle dance that you didn't know before?
