The Language of Movement
In the pitch-black darkness of a beehive, honeybees have developed one of the most sophisticated communication systems in the world: the Waggle Dance. When a scout finds a rich source of nectar, she performs a series of figure-eight movements.
Because her sisters can't see her, they crowd around and 'read' the dance by touching her with their antennae, translating her vibrations into a flight plan.
Solar Navigation
The core of the dance is a mathematical translation of the sun's position. The bee uses the vertical line of the honeycomb to represent the sun's current location in the sky.
If she dances at a 40-degree angle to the right of the vertical line, she is telling her hive-mates to fly 40 degrees to the right of the sun. It is a biological compass that works even on cloudy days.
Measuring the Miles
The 'waggle' part of the dance—where the bee shakes her abdomen—is how she communicates distance. The duration of this wiggle is precise: roughly one second of waggling equals one kilometer of flight.
By timing these vibrations, the other bees know exactly how much 'fuel' (honey) they need to eat to survive the round trip to the flower patch.
Quality Control
Not every flower is worth the trip. A bee also communicates the quality of the find through the intensity of her dance. If the nectar is exceptionally sweet, she will dance with violent energy.
