Each of these three segments has a pair of legs. On a grasshopper and many other winged insects, the mesothorax and usually the metathorax. You will notice on the grasshopper the large plate just in back of its head which looks a little like a saddle. The pronotum extends from the head to the base of the wings. Most kinds of grasshoppers have two pairs of wings .
Some species have short, useless wings, and others have no wings at all.
A grasshopper's front wings are narrow and tough. They cover and protect the large, thin hind wings. When the insect rests, its hind wings fold up like fans under its front wings. The upstroke helps keep the grasshopper moving until the wings reach the position for the next downstroke. A grasshopper has six legs, and uses all of them when it walks.
