Biologists have long been impressed by the navigation ability of bees and other Hymenoptera. In 1882, Fabre wrote about an experiment with bees and solitary wasps. He caught insects near their nests and carried them in containers to locations, some up to several kilometers distant. Surprisingly, many were able to return to their nest. This was true even if the insects were placed in dark containers and transported by circuitous routes, or tumbled within the containers, all designed to disrupt navigational cues such as compass direction, polarized light and path integration.
