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.
inherited
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).
When an insect sheds its outer skin, it's called molting.
