What Are Insects for Kids? Insects are tiny animals that live almost everywhere: in backyards, forests, and even on our bodies.
They come in a staggering variety of shapes and sizes, from the small flea to the majestic monarch butterfly. To understand what an insect is, we need to look at its basic characteristics.
Insects belong to the class Insecta and have three main body parts: the head, thorax, and abdomen. They also have six legs, which they use for walking, running, and flying.
