True Bug

Heteroptera is a group of about 40,000 species of insects in the Hemiptera. Sometimes called "true bugs" that name more commonly refers to Hemiptera as a whole, and "typical bugs" might be used as a more unequivocal alternative since among the Hemiptera the heteropterans are most consistently and universally termed "bugs". "Heteroptera" is Greek for "different wings": most species have forewings with both membranous and hardened portions (called hemelytra); members of the primitive Enicocephalomorpha have wings that are completely membranous.

The name "Heteroptera" is used in two very different ways in modern classifications; in Linnean nomenclature it commonly appears as a suborder within the order Hemiptera, where it can be paraphyletic or monophyletic depending on its delimitation. In phylogenetic nomenclature it is used as an unranked clade within the Prosorrhyncha clade which in turn is in the Hemiptera clade. This results from the realization that the Coleorrhyncha are actually just a "living fossil" relative of the traditional Heteroptera, close enough to them to be actually united with that group.(http://en.wikipedia.org/wiki/Heteroptera)
