Bees fed at end of tunnel. Back at the hive, they danced the waggle dance. Bees fed at end of tunnel decorated with horizontal stripes. These created no flicker as the bees flew, and on their return to the hive they danced the round dance. You can read about this second set of experiments in Srinivasan, et.
Recruits respond to the misinformation given by returning scouts.
More recently, the Esch and Srinivasan groups have teamed up to show that naive foragers are fooled by the misinformation that the returning scouts give them. When scouts were fed only 11 m from the hive but at the far end of a striped tunnel, they danced the waggle dance back at the hive as though the food had been 70 m away. You can read about these experiments in Ungless, et. But von Frisch also noted that the direction of the straight portion of the waggle dance varied with the direction of the food source from the hive and the time of day. At any one time, the direction changes with the location of the food.
