What is an insect's body like?
In Latin, the word insect means 'cut in sections'. An insect's body has three parts: a head, a thorax, and an abdomen. The head has a pair of antennae, eyes and a mouth. The head is used for eating, to feel around and to gather information. Some insects have simple eyes like ours, but most have complex eyes made up of six-sided lenses. The second part of the body, the thorax, supports the six legs and wings. The last part, the abdomen, digests the food and helps the insect breathe, since insects do not have separate noses like we do.
