Caterpillars after coming out from the eggs after hatching eats all day and night for about 25 to 30 days. As it eats more food than its weight of the body, their skin splits and they have the need to shed their skin.
Assuming you are refering to the stage when the catapillar emerges from the cacoon as a moth or butterfly, molting would be the correct term. The cacoon is molted and the adult emerges. The immediately follows metamorphasis.
A caterpillar sheds its skin because its skin gets too tight. The caterpillar needs to grow so that is why it sheds its skin. Eventually the caterpillar will turn into a crysalis or the pupa stage.
Molting is when a caterpillar sheds its skin. It does this several times in its stage of being a caterpillar until it makes the cocoon.
