"Oh, I was going to forget their feelers," he added. "You can see them, Norah, one on each side of the head. These are supposed to be organs of hearing and feeling. Now, Fred, can you think of anything else?""Well, we must not forget the mouth," said Fred. "In insects, as in other animals, the form of themouth depends on the kind of food. The beetle has a pair of strong biting jaws or mandibles and another pair of chewing jaws, and so have all insects that live on solid animal or vegetable food. They bite off their food with their mandibles, and chew it with their chewing teeth.
"Other insects, such as the bee, the common house-fly, and the butterfly, live on juices, which they suck up through a trunk. They have no jaws.
"Remember one thing. Whenever insects have jaws they always open sideways, and not up and down as ours do."SUMMARY
The word in-sect means "cut into." The body is in three parts-head, chest, and belly, and is made up of ringed segments. Insects have no brain. The eyes are at the sides of the head; each eye is a cluster of small eyes. Some insects have jaws for biting their food. The jaws always open sideways. Some have trunks for sucking up the food on which they live.
