What is an insect antenna?
Quick Answer
An insect antenna is a sensory organ used to detect smells, touch, vibration, and sometimes humidity or temperature. Antennae are important for finding food, mates, and navigating the environment.
The Full Story
Insect antennae are paired sensory structures located on the head. They are packed with receptors that help insects smell chemical cues, sense air currents, and detect nearby objects. Different insects have antennae shaped like threads, clubs, feathers, or elbows depending on their lifestyle. For example, moths often have highly sensitive antennae for detecting pheromones, while beetles and ants use theirs to explore and communicate. Antennae are one of the clearest features separating insects from arachnids, which do not have them.
