Final answer:
The nymphs of a grasshopper do not fly because they have not yet developed fully developed wings.
Step-by-step explanation:
No, the nymphs of a grasshopper do not fly. Grasshoppers undergo incomplete metamorphosis, which means that they do not undergo a dramatic transformation from larva to adult like insects that undergo complete metamorphosis, such as butterflies. Instead, grasshoppers develop through a series of molts, where they shed their exoskeleton and grow larger with each molt. The adult grasshoppers have wings and are capable of flying, but the nymphs do not have fully developed wings, so they are unable to fly.
