Grasshoppers are medium to large insects. Adult length is 1 to 7 cm, 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.rasshoppers are medium to large insects.

The mouthparts also aid in attachment to the host. Chewing lice have ventral chewing mandibles; they feed on epidermal debris, primarily skin scales, sebaceous secretions, and feathers, if applicable. The heads of chewing lice have a blunted appearance, with the head being wider than the thorax.
