Insects comprise roughly half of the animal kingdom, and they live everywhere. Most of us think life would be better without bugs. In fact, life would be impossible without them. Without the pinhead-sized chocolate midge, cocoa flowers would not pollinate. The fruit fly is essential to medical and biological research experiments. Insects turn dead plants and animals into soil. They control organisms that are harmful to humans. Sverdrup-Thygeson shows us that there is more variety among insects than we can even imagine, and the more you learn about insects, the more fascinating they become. -- adapted from jacket
