1. External Structure of Insects, Functions & Locomotion
Insect surface: exoskeleton & epidermis
Head: Mouthparts, Antennae, Eyes
Thorax:Thoracic segments, Wings, Legs
Abdomen: Segments,Ovipositor,Cerci,Style

3. THE INSECT SURFACE Dermal gland: produce pheromone, repellant
(Exoskeleton) - glycoprotein
Dermal gland:
produce pheromone,
repellant

4. Function of Exoskeleton
Body support
Protection
Water conservation
Location of muscle attachment - allows movement
Colouration & Camouflage
