insect

Insects are small, six-legged creatures that are found all over the world. They have a hard exoskeleton, three body parts, and two pairs of wings.

Insects are an important part of the ecosystem. They pollinate plants, eat other insects, and break down dead matter.

Some insects, such as bees, butterflies, and ladybugs, are helpful to humans. Others, such as mosquitoes, flies, and cockroaches, can be pests.
