Bee dance may be more complex than thought

Bees use a complex “waggle” dance to communicate with hivemates about the direction and distance to sources of food. Through a sequence of waggles and vibrations, the dance communicates direction relative to the sun, distance from the hive, and quality of the food source–all in the complete darkness inside a hive.

Discovery and decoding of this remarkable form of communication won Karl von Frisch the nobel prize in 1973. Now, UCSD professor James Nieh has built on this research by finding that some members of the bee audience may stop the dancer if they know about predators or other risks at the food source. By doing so, the hive improves its collective intelligence.

Studies of bee waggling have led to discoveries about the complex communication patterns of true social insects such as bees, wasps, and ants. The “stop” signal is only the second known example of a sophisticated insect society using “negative feedback” — signals that tell others to stop a behavior.

British bees go urban!

A new and improved design of beehive could be used by city dwellers to harvest up to 20 kilograms (44 pounds) of their own honey each year, according to Natural England, a British government conservation agency. The hives could also help stem the decline of bee populations. Continue reading
