A round dance is the communicative behaviour of a foraging honey bee (Apis mellifera), in which she moves on the comb in close circles, alternating right and then left. It is previously believed that the round dance indicates that the forager has located a profitable food source close to the hive and the round dance transitions into the waggle dance when food sources are more than 50 meters away. Recent research shows that bees have only one dance that always encodes distance and direction to the food source, but that precision and expression of this information depends on the distance to the target; therefore, the use of "round dance" is outdated. Elements of the round dance also provide information regarding the forager's subjective evaluation of the food source's profitability.
