How Bees Communicate: The Waggle Dance Explained
A honeybee returning from a flower patch performs a precise figure-eight dance on the vertical comb face of its hive. The angle of her body relative to gravity encodes compass direction. The duration of the waggle run encodes distance. Her nestmates read both signals and fly directly to a resource they have never visited. This is not instinct in any simple sense — it is a symbolic language, and decoding it took a biologist decades of careful experiment.
