Insects
An insect belongs to the class of invertebrates called arthropods. Regardless of size, all adult insects have a similar body structure, which includes a head, a thorax, and an abdomen. The head contains not only the brain and mouth but also the sensory organs, usually a pair of eyes and a pair of antennae. The thorax is the central part of the insect’s body where the wings and legs are attached, allowing the insect to move in the air and on feeding surfaces. Typically, insects have three pairs of legs and two pairs of wings. The third part of the insect’s body structure consists of an abdomen where food is processed and also where the reproductive organs are found.Describe the structure of an insect and explain why a spider is not strictly considered an insect.
