The waggle dance and the round dance are two forms of dance behaviour that are part of a continuous transition. As the distance between the resource and the hive increases, the round dance transforms into variations of a transitional dance, which, when communicating resources at even greater distances, becomes the waggle dance. Austrian ethologist and Nobel laureate Karl von Frisch was one of the first who translated the meaning of the waggle dance. 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. The direction and duration of waggle runs are closely correlated with the direction and distance of the resource being advertised by the dancing bee.
In an experiment with capture and relocation of bees exposed to a waggle dance the bees followed the path that would have taken them to an experimental feeder had they not been displaced. Waggle dancing bees that have been in the nest for an extended time adjust the angles of their dances to accommodate the changing direction of the sun. Therefore, bees that follow the waggle run of the dance are still correctly led to the food source even though its angle relative to the sun has changed. The consumption of ethanol by foraging bees has been shown to reduce waggle dance activity and increase occurrence of the tremble dance. The scientists explain that the bees associate the dead bee with the presence of a predator at the food source. Though first decoded by Karl von Frisch, dancing behavior in bees had been observed and described multiple times prior. Around 100 years before Frisch’s discovery, Nicholas Unhoch described dancing behavior of bees as being an indulgence “in certain pleasures and jollity”.
