Honeybees communicate the location of food through a movement biologists call the waggle dance. A returning forager traces a figure-eight pattern on the comb, and the angle of its straight run relative to vertical encodes the direction of the food in relation to the sun, while the duration of the waggling indicates distance. Remarkably, bees adjust this angle over the course of the day to account for the sun's movement across the sky, even when they remain inside the dark hive and cannot see it. This suggests that the dance relies not merely on what a bee currently observes but on an internal sense of time the insect carries with it.
