True Bug

True bugs comprise cicadas, aphids, planthoppers, leafhoppers, and shield bugs. They are characterized by sucking mouthparts, forewings hardened at base but membranous at ends. They keep their wings flat over their abdomen in an X shape or like a tent over their body at rest. Many feed on plants, but some are predacious or parasites.
