What Insects Shed Their Skin? Why Do They Do It?
Insects shed their skin, also known as molting or ecdysis, to accommodate growth and development. As insects grow, their exoskeleton, which is a hard outer shell made of chitin, becomes too small. To remedy this, they shed their old exoskeleton and secrete a new, larger one.
Molting is a complex process that involves several stages:
- Proecdysis: The insect stops feeding and its cuticle, the outermost layer of the exoskeleton, loosens.
- Ecdysis: The old exoskeleton splits along the back, and the insect emerges.
- Post-ecdysis: The new cuticle hardens, and the insect resumes feeding.
Insects shed their skin multiple times during their lifetime, from nymph to adult. The frequency and duration of molting vary depending on the species.
The process of shedding their skin also serves other functions:
- Protection: The new exoskeleton provides a fresh, protective layer against predators and the elements.
- Repair: Insects can repair minor injuries during molting by replacing the damaged part of the exoskeleton.
- Reproduction: Females of some species store sperm in a specialized pouch that is shed during molting.
