How do bee dances communicate the location and strength of food sources?

Bees communicate the location and quality of food sources to their colony through rhythmic movements known as dances, a behavior famously studied by Karl von Frisch. The type of dance performed depends primarily on the distance of the food source from the hive.12

  • Round Dance: When a food source is nearby—typically within 75 meters (about 250 feet)—a bee performs a circling dance to indicate its presence.13
  • Waggle Dance: For more distant food sources, a bee performs a waggle dance. This involves a figure-eight pattern with a straight "walk" in the middle, accompanied by wing fluttering. This movement conveys both the direction and the abundance of the food.41

Through these dancelike movements, worker bees effectively share critical information regarding the distance, direction, quantity, and quality of resources, allowing the colony to forage efficiently. Additionally, bees use the Sun as a compass and can navigate by remembering patterns of polarized light, ensuring they can accurately communicate these locations even when the Sun is not directly visible.21
