True bugs usually have four wings; the front pair is thick and leathery at the base and thin and membranous at the tip. These wings are held flat over the back so that the tips overlap each other. A few species are wingless. Some are beneficial and some are pests. All true bugs have piercing-sucking mouthparts, which form a noticeable beak. Metamorphosis is incomplete. Many true bugs possess stink glands and give off an unpleasant odor when disturbed or handled.

Most true bugs live on land, but some, such as the giant water bug and water striders, live in or on water. Usually, those that live on land feed on plant juices or are predators of other insects, but a few, such as the bed bug, are parasites of humans and other animals.
