How do cuticles help an insect?

Cuticles help insects by providing a protective exoskeleton that shields their bodies from physical damage, dehydration, and pathogens. Made primarily of chitin, the cuticle offers structural support and also aids in locomotion by allowing muscles to attach and function effectively. Additionally, the cuticle can help regulate water loss, which is crucial for survival in various environments. Overall, it plays a vital role in an insect's overall health and adaptability.
