[6] The California orange-winged grasshopper is known for making a cracking noise while flying by rubbing its front wings together. [7]
The third instar is up to 2 cm long and the wing pads are triangular. The fourth instar has venation in its wing pads. The fifth instar is up to 3.5 cm long and the wing pads have changed position. By the sixth instar, the wings have elongated. [3] This species overwinters as an adult rather than in the egg, as many other grasshoppers do. [3]

It is composed of a fluid plasma in which hemolymph cells called hemocytes are suspended. In addition to hemocytes, the plasma also contains many chemicals. It is the major tissue type of the open circulatory system characteristic of arthropods (for example, arachnids, crustaceans and insects).
Eumastacidae are a family of grasshoppers sometimes known as monkey- or matchstick grasshoppers. They usually have thin legs that are held folded at right angles to the body, sometimes close to the horizontal plane. Many species are wingless and the head is at an angle with the top of the head often jutting above the line of the thorax and abdomen.
Acrididae are the predominant family of grasshoppers, comprising some 10,000 of the 11,000 species of the entire suborder Caelifera.The Acrididae are best known because all locusts (swarming grasshoppers) are of the Acrididae.
