Most species of grasshoppers have two pairs of wings. One pair is narrow, and the other pair is wide. Certain species of grasshoppers, specifically the males of the species, attract females by rubbing their wings against their legs or vibrating their wings.
When grasshoppers fly, they use their powerful legs as a type of catapult to give them an extra spring into the air. Grasshoppers also use their wings to avoid predators, flying away when danger is present. Some grasshoppers eat plants that are toxic and store the toxins in their bodies to protect them from other insects and animals.
