A group of grasshoppers is called a cloud. Grasshoppers are insects that range in size from ½ inch to 2¾ inches. They have two pairs of wings and six legs, four in front and two in the back. Unlike katydids and crickets, grasshoppers have short horned antennae.
Compound eyes give insects an expanded field of view, according to University of Minnesota (UMN). Compound-eyed insects, such as the dragonfly, can see objects from all angles except for the blind spot their bodies create. Some boast dual-vision systems which allow them to see darkness, light and color. Compound eyes also help insects estimate the distance between their bodies and other objects, states PawNation.
Grasshoppers are not known for biting though they may occasionally bite a predator as a defense mechanism. Although grasshoppers have very strong jaws for tearing vegetation, they prefer jumping away to avoid capture rather than confronting predators.
