A nymph is a young form of certain insects that looks like a smaller, incomplete version of the adult. When a grasshopper hatches from its egg, it emerges as a nymph: it has the basic grasshopper shape but lacks fully developed wings. As the nymph grows, it sheds its outer skin several times, gradually developing more adult features with each molt. This process, called incomplete metamorphosis, is different from how butterflies develop. Butterflies go through a dramatic transformation inside a chrysalis, but insects like grasshoppers, dragonflies, and cicadas spend weeks or months as nymphs, looking recognizably like their adult forms while slowly maturing.

In ancient Greek and Roman mythology, nymphs were also nature spirits: beautiful, immortal beings associated with specific places like forests, rivers, or mountains. These mythological nymphs appear frequently in classical stories, often helping heroes or playing tricks on mortals. You might encounter them in books about mythology or fantasy stories inspired by ancient legends.
