After shedding its exoskeleton, a crayfish hides because it becomes vulnerable to injury and attacks from predators. The crayfish sheds its exoskeleton when it needs to grow. It can take two to three days for a crayfish to re-grow a new and larger one.
An insect does this to grow. It expands rapidly before the next exoskeleton hardens.
an arthropod sheds it old exoskeleton when it has grown to a point where it needs a larger exoskeleton. This process is called ecdysis.
An animal (insect) with an exoskeleton still grows under its exoskeleton like any other animal (insect). The exoskeleton is like a suit of armor, when the animal (insect) grows to big to fit inside its exoskeleton it sheds it, and a newer exoskeleton will grow to fit the animal (insect).

An exoskeleton is a layer of skin that is like and "exo" (outside) "skeleton", that an animal sheds
As the arthropod grows up, the exoskeleton sheds in order for the arthropod to grow inside of it.
