Hemiptera - Heteroptera (True Bugs)
(after Gross 1975): The Heteroptera is a suborder of the Hemiptera. Their dorsal surface is generally somewhat flattened and both pairs of wings lie flat over the abdomen when at rest. In almost all heteropteran families the fore wings are hardened and thickened in the basal half whilst the distal half remains membranous. This results in a structure which is half hardened like the elytra of a beetle and half membranous like the fore wing of a wasp.
