Honeybees communicate through a remarkable movement known as the waggle dance. When a worker finds a good source of nectar, she returns to the hive and walks in a figure-eight pattern, shaking her body during the straight part of the run. The angle of that run, measured against the vertical, tells the other bees the direction of the flowers relative to the sun. The length of the waggle shows the distance: roughly one second of dancing for every kilometer of flight. In this way, a single scout can guide hundreds of foragers to the food she has found.
