The Waggle Dance of the Honeybee

How Do Honeybees Communicate the Location of Food?

The Behavior of Honeybees

  • Aristotle documented honeybee behavior, noting how colonies coordinate worker activities, suggesting intelligent behavior in what seems like random swarming.
  • Foraging honeybees discover food sources individually, raising questions about their communication methods to share this information with others.

Experiments by Carl von Frisch

  • Austrian biologist Carl von Frisch conducted experiments in the 1940s to explore honeybee communication; modern researchers at Georgia Tech replicated these studies.
  • In a two-feeder experiment, bees were marked with different colored paints to track which feeder they visited and observe their dance patterns upon returning.

Dance Language of Bees

  • Returning bees perform a figure-eight dance that varies based on the feeding source; the orientation of their dances correlates with the angle between feeders and hive.
  • The angle of rotation in their dance provides clues about food location, revealing a complex grammar within honeybee communication.

Tools for Navigation

  • Honeybees utilize ultraviolet and polarized light to determine the sun's position, even under cloudy conditions; this acts as a solar compass for navigation.
  • Their internal clock allows them to adjust for the sun's movement throughout the day, enabling accurate navigation even after being inside a dark hive.

Communication Mechanism

  • Bees use gravity as a reference point for direction (up/down), pairing it with solar positioning to create a simple language indicating where to find food.
  • The angle of a bee's dance indicates direction relative to the sun; duration reflects distance—longer dances mean further distances while shorter ones indicate proximity.

Information Encoding in Dance

  • The central waggle section of the dance conveys distance information: one second longer per kilometer away from food. Close food results in circular dances.
  • Distance is also influenced by environmental factors like wind; thus, bees may adjust their dance based on energy expenditure during travel.

Future Research Directions

Video description

How can honeybees communicate the locations of new food sources? Austrian biologist, Karl Von Frisch, devised an experiment to find out! By pairing the direction of the sun with the flow of gravity, honeybees are able to explain the distant locations of food by dancing. "The Waggle Dance of the Honeybee" details the design of Von Frisch's famous experiment and explains the precise grammar of the honeybees dance language with high quality visualizations. This video is a design documentary, developed by scientists at Georgia Tech's College of Computing in order to better understand and share with others, the complex behaviors that can arise in social insects. Their goal at the Multi-Agent Robotics and Systems (MARS) Laboratory is to harness new computer vision techniques to accelerate biologists' research in animal behavior. This behavioral research is then used, in turn, to design better systems of autonomous robots. For additional detail on the MARS lab at Georgia Tech, please visit http://www.bio-tracking.org/.
