Insect Antennae
- All insects except Protura possess a pair of antennae that function almost exclusively in sensory perception.
- It helps in motion and orientation, odor, sound, humidity, and a variety of chemical cues.
- Antennae vary greatly among insects, but all follow a basic plan: segments 1 and 2 are termed the scape and pedicel, respectively.
- The remaining antennal segments (flagellomeres) are jointly called the flagellum.
