The Hemiptera /hɛˈmɪptərə/ or true bugs are an order of insects comprising around 50,000–80,000 species of groups such as the cicadas, aphids, planthoppers, leafhoppers and shield bugs. They range in size from 1 mm (0.04 in) to around 15 cm (6 in), and share a common arrangement of sucking mouthparts. The name true bugs is sometimes limited to the suborder Heteroptera.
