Chemoreceptors respond to chemical molecules. Insects use them to locate food, recognize mates, avoid toxins, and select egg-laying sites.

Mechanoreceptors detect physical forces such as touch, vibration, stretch, or air movement. Sensory hairs and chordotonal organs are common insect examples.

Photoreceptors detect light and begin visual processing. They occur in compound eyes and ocelli, helping insects respond to movement, day length, and orientation cues.

Ganglia act as local control centers. Insects can coordinate segmental movements through thoracic and abdominal ganglia, sometimes even with partial independence from the brain.
