A grass hopper goes through three different stages of growth: egg, nymph, and adult. In the image below, you can see that the spotted grass hopper is an adult. When a grass hopper is an egg, it has not yet become hatched open. When it does hatch it will  appear as a nymph, the baby or young form that looks green-ish in color. Finally, the adult, the full grown stage, will be the last stage of a grass hoppers life cycle. Adult male grass hoppers will make noises that can attract female grass hoppers, who are able to mate with the male grass hopper and can reproduce or have babies. After the male is done mating, it will die, and that restarts the whole grass hopper life cycle. Now you know the three different stages of a grass hopper life cycle.
