The Hemiptera, for some reason, get the distinction of being dubbed "bugs". While the word "bug" is generally used to describe any or all arthropods, in binomial nomenclature it refers specifically to the Hemiptera. An incredibly diverse group of insects, they feed with the aid of piercing mouthparts enclosed in a beak-like rostrum, on both plants and animals. They have been broken into four suborders: Heteroptera (the true bugs), Auchenorrhyncha (the cicadas, lanternflies and hoppers), Sternorrhyncha (the aphids and scales), and Coleorrhyncha (the moss bugs). The ordinal name Hemiptera, is derived from Greek words meaning “half-wing”. Hemiptera appear in the fossil record during the Permian (280-225 million years ago). There are about 82,000 known species with more being described all the time.
