Detailed explanation-1: -In arthropods, such as insects, arachnids and crustaceans, moulting is the shedding of the exoskeleton (which is often called its shell), typically to let the organism grow. This process is called ecdysis.
Detailed explanation-2: -Molting is the shedding of the exoskeleton (cuticle) of the previous life stage. Without molting, an insect cannot grow.
Detailed explanation-3: -The Process of Molting In molting, the epidermis separates from the outermost cuticle. Then, the epidermis forms a protective layer around itself and secretes chemicals that break down the insides of the old cuticle. That protective layer becomes part of the new cuticle.
Detailed explanation-4: -An instar is a developmental stage of insects, between each moult until sexual maturity is reached.
