An insect’s body divides into three sections. The head holds the eyes, antennae, and mouthparts. The thorax bears three pairs of jointed legs and two pairs of wings. The abdomen contains the digestive system and the sex organs. Most insects undergo a complete change between the larval stage and the adult form.
There are more different types of insect than of any other kind of animal, with over one million identified species. Most live on land or in the air, but a number also live in fresh water.
