Upon returning to its hive, a European honeybee communicates to other worker bees the presence of a nearby food source it has discovered by  vibrating its wings at varying frequencies.
Honeybees have evolved an extraordinary form of communication known as the "waggle" dance. It is highly symbolic, separated as it is in both time and space from the activity it grew out of (discovering a nectar source) and the activity it will spur on (getting other bees to go to that nectar source).
Some use body language and eye contact, while others have vocal patterns. Honey bees have two primary methods of talking to one another: movement and odor. Bees use these behaviors to send messages throughout the colony, locate a nearby food source, and communicate other information.
