Grasshoppers usually are a shade of brown, green or black. They have large hind legs that help them jump long distances, hence their name. Adult grasshoppers also have two sets of wings, with the forewings being slender and the hindwings large.
Grasshoppers are medium to large insects. Adult length is one to seven centimeters, depending on the species. Like their relatives the 'katydids' and 'crickets', they have chewing mouthparts, two pairs of wings, one narrow and tough, the other wide and flexible, and long hind legs for jumping
