Molting: Stick insects shed their exoskeletons as part of their growth process – just like teens shed their questionable fashion choices!
Molting: The Key to Stick Insect Growth
Molting is a vital process in the growth of stick insects. It lets them shed their old exoskeleton and mature into larger individuals. This process is essential for their development.
To comprehend molting’s importance, here’s a step-by-step guide:
-
Preparation:
- Stick insects reduce their food intake.
- They become less active and rest more.
- They start producing a new exoskeleton under their current one.
-
Shedding:
- The old exoskeleton splits along predetermined lines.
- Stick insects carefully wriggle out of their old shell.
- Their new exoskeleton is soft and vulnerable.
-
Hardening:
- After molting, they wait for their new exoskeleton to harden.
- During this period, they may appear pale due to lack of pigmentation.
- Once the exoskeleton hardens, they regain their color and strength.
Nutrition and environment are important for successful growth. A varied diet of leaves from suitable plants provides essential nutrients.
In 1928, Paul Dohrn discovered that young stick insects go through multiple molts before reaching maturity. This highlighted molting’s importance in the growth and development of these creatures.
