A bee's antenna is packed with thousands of sensory cells. Bees use their antennae to smell, taste, and hear, as well as to detect changes in temperature, wind, and humidity.
These sense organs not only help the bee steer through the outside world, they also help it navigate the social world of the hive. Bees communicate in large part through chemical pheromones, with different odors signaling everything from alarm to an individual bee's status.
