Absolutely amazing! Makes me want to throw The Little Book of Bees out the window and go out and buy myself a big screen TV.
Thanks for the information WW, what great science by the Japanese bees!
These  contributions  to  this AWAD compendium of bees are bland  in comparison but they are in me, and must come out.
 * The famous dance of the honeybees to tell co-workers the location of nectar fields is adjusted by the dancers  to take into account almost  infinitesimal  daily shifts of the  magnetic field of the Earth.
 * Distances to food sources are communicated to hivemates by the speed of the dance. The faster the dance, the closer the food. The slower the dance the further the food. Some investigators believe that the distances to food sources are measured by the locating bee  by self-counting the amount of energy expended by the bee in her  direct flight home which is then translated into the speed of the dance - a neat little biological calculation. 
 * All honeybee languages are not the same. Though all dance, some races of honeybees speak in a "dialect" that is all but incomprehensible to other bees of their own  species. The sophistication of information transfer is likely environmentally determined.
