Insects

When people talk about “insects,” they often mean pests or disease carriers such as bedbugs, houseflies, beetles, mosquitoes, fleas, and hornets. To be fair, though, many insects are beneficial to humans, albeit sometimes indirectly: they pollinate plants, produce useful substances, control pest insects, act as scavengers, and serve as food for other animals. Some insects, such as butterflies, are beautiful to behold, and insects such as ladybugs flaunt eye-catching colors and patterns.
