wing (wings) noun - membranaceous, reticulated (having numerous lines, like a net) instruments of flight, attached laterally to the thorax. Among invertebrates, wings are a characteristic feature of the Pterygota (winged insects), though some groups have lost them secondarily. Most members of "Pterygota" have two pairs (4) wings:
forewings--attached to the mesothorax
hindwings (reduced or lacking in some groups)--attached to the metathorax
Some orders have distinctive modifications to the wings:
Coleoptera (beetles)--forewings are hardened, called elytra
Orthoptera (grasshoppers and allies), Dermaptera (Earwigs)--forewings called tegmina
Diptera (flies)--hindwings are reduced to knobs, called halteres
