Bees communicate in the hive primarily through a complex system of dance known as the "waggle dance." This dance involves bees moving in specific patterns to convey information about the location of food sources, such as nectar and pollen. Through this dance, bees are able to communicate the direction, distance, and quality of the food source to other members of the colony. Additionally, bees also use pheromones to communicate with each other, signaling alarm, marking food sources, and coordinating activities within the hive.
