If you could look inside an insect’s body, you wouldn’t see any bones. But insects do have skeletons!  Insects differ from creatures with back-bones, such as humans, horses, dogs and fishes.  These animals have hard skeletons inside their bodies. Your skeleton is made of bone, and the rest of your body is shaped around it.

An insect’s skeleton though, is a tough outer shell.  It provides support and protection for the insect’s soft insides.  Some insects, especially beetles have hard, heavy skeletons.  Others, such as butterflies have light, thin skeleton. – Dick Rogers
