I vaguely remember a study of bees in India south of the Tropic of Cancer, and there bees tended to get confused and stayed in the hives near local noon, at the times of the year the sun was nearly directly overhead at local noon. Also bees trained to forage at a particular sspot would fly off 180 degrees if their hive was moved from a spot where the sun was to the south during local noon to a spot where the sun was to the north during local noon. -Mike
