    Head: The head has large compound eyes and, if mouthparts are present, they are almost always a drinking straw-like proboscis. Scales: Scales cover the external surface of the body and appendages. Thorax: The prothorax is usually reduced. Wings: Two pairs of wings are present in almost all taxa. The wings have very few cross veins.
