What is the primary function of a bee's antennae?

The primary function of a bee's antennae is to sense chemicals, odors, and environmental changes. Antennae are equipped with specialized sensory cells that allow bees to detect pheromones, which are chemical signals used for communication within the hive, as well as other environmental scents that help them locate food sources and identify suitable nesting sites. This chemical sensing is crucial for the survival and social structure of bees, enabling them to interact effectively with their environment and other members of their colony.

While antennae do play important roles in stabilizing flight and detecting certain sounds, the most critical and specialized function lies in their ability to sense chemical cues. This ability supports bees in foraging for food, navigating, and engaging in reproductive behaviors. Storing nectar is a function performed primarily by the bees' specialized body structures, such as the honey stomach, rather than the antennae. Thus, the correct answer emphasizes the antennae’s role in chemical and environmental detection, which is fundamental to the behavior and ecology of bees.
