Because the outer covering (or exoskeleton) doesn't stretch as ordinary skin does. The insect basically 'outgrows' its skin, and moults. The newly emerged insect will often gulp air to inflate its body before the new exoskeleton has time to dry - allowing for new growth.
Caterpillars molt so they can achieve a bigger size. Molting helps the caterpillar shed excess skin when they are getting bigger.
Some insects which have a hard outer covering needs to moult but smooth skin animals do not need to moult

Where do animals who moults their skin leave it?
Insects and reptiles tend to moult. They don't have the same sort of skin as mammals do. In order to get bigger, they have to shed their skin to expand. Most just abandon the skin where it is and you can find snake skins and insect shells in the right places.

What is a stick insect life cycle?
The female stick insect mates (some can lay eggs without mating), sticking her eggs to leaves or just on the ground. She may lay any number between 100 and 1200. The eggs often look like plant seeds and sometimes take several months to hatch. Baby insects (nymphs) look very like their parents. As each stage (or instar) of the insect grows big enough, it moults, that is, it sheds its outer skeleton, which it eats. After several moults it develops into the fully grown stick insect. Wings develop before the final moult. All males and the females of many species have wings, though usually only the males can fly. Stick insects live about 12 months, sometimes longer when kept as pets.
