The Waggle Dance

leave a comment »

Wikipedia:
Waggle dance is a term used in beekeeping and ethology for a particular figure-eight dance of the honey bee. By performing this dance, successful foragers can share with their hive mates information about the direction and distance to patches of flowers yielding nectar and pollen, to water sources, or to new housing locations. Thus the waggle dance is a mechanism whereby successful foragers can recruit other bees in their colony to good locations for collecting various resources. It was once thought that bees had two distinct recruitment dances — round dances and waggle dances — the former for indicating nearby targets and the latter for indicating distant targets, but it is now known that a round dance is simply a waggle dance with a very short waggle run. Austrian ethologist and Nobel laureate Karl von Frisch was one of the first who translated the meaning of the waggle dance.

Figure-Eight-Shaped Waggle Dance of the Honeybee (Apis mellifera). A waggle run oriented 45° to the right of ‘up’ on the vertical comb indicates a food source 45° to the right of the direction of the sun outside the hive. The abdomen of the dancer appears blurred because of the rapid motion from side to side.

A waggle dance consists of one to 100 or more circuits, each of which consists of two phases: the waggle phase and the return phase. A worker bee’s waggle dance involves running through a small figure-eight pattern: a waggle run (aka waggle phase) followed by a turn to the right to circle back to the starting point (aka return phase), another waggle run, followed by a turn and circle to the left, and so on in a regular alternation between right and left turns after waggle runs.
