Insects have hard outer coverings
Unlike our skin, the hard outer covering of insects cannot stretch and grow along with the insect. To grow bigger, an insect must shed its hard outer covering in a process called moulting. Its new, and bigger, outer covering take a few minutes to dry and harden, protecting its soft body.
