Eyes, Antenna and Hairs on their cuticle
Note: There are no diagrams or attachments provided.
Step-by-step explanation:
Eyes
The eyes of insects serve the function of vision. Insects eyes are of two kinds; simple eyes or ocelli, and compound eyes. The simple eyes or ocelli can sense only light, darkness, and movement. The compound eye which consists of individual light receptive units called ommatidia can distinguish brightness and colour. More ommatidia in an insect's compound eye results in more clarity of vision
Hairs
Tiny hairs known as setae found all over the cuticle of insects are sensitive to vibration touch and sound and therefore serve as sense organs of touch and sound for insects.
Antenna
The antenna in insects serves various sensory functions such as sensing touch, air motion, heat, vibration (sound), and especially smell or taste.
