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.

Insect mandibles are a pair of appendages near the insectâs mouth, and the most anterior of the three pairs of oral appendages (the labrum is more anterior, but is a single fused structure).Their function is typically to grasp, crush, or cut the insectâs food, or to defend against predators or rivals.ll but a few adult Lepidoptera lack mandibles, with the remaining mouthparts forming an elongated sucking tube. The exception is the mandibulate moths (family Micropterigidae), which have fully developed mandibles as adults.
