A nymph (Greek: νύμφη, nymphē) in Greek mythology and in Latin mythology is a minor female nature deity typically associated with a particular location or landform. Different from other goddesses, nymphs are generally regarded as divine spirits who animate nature, and are usually depicted as beautiful, young nubile maidens who love to dance and sing; their amorous freedom sets them apart from the restricted and chaste wives and daughters of the Greek polis. They are beloved by many and dwell in mountainous regions and forests by lakes and streams. Although they would never die of old age nor illness, and could give birth to fully immortal children if mated to a god, they themselves were not necessarily immortal, and could be beholden to death in various forms. Charybdis and Scylla were once nymphs.
Other nymphs, always in the shape of young maidens, were part of the retinue of a god, such as Dionysus, Hermes, or Pan, or a goddess, generally the huntress Artemis. Nymphs were the frequent target of satyrs.
In biology, a nymph is the immature form of some invertebrates, particularly insects, which undergoes gradual metamorphosis (hemimetabolism) before reaching its adult stage. Unlike a typical larva, a nymph's overall form already resembles that of the adult. In addition, while a nymph moults it never enters a pupal stage. Instead, the final moult results in an adult insect. Nymphs undergo multiple stages of development called instars.
This is the case, for example, in Orthoptera (crickets and grasshoppers), Hemiptera (cicadas, shield bugs, etc.), mayflies, termites, cockroaches, mantises, stoneflies and Odonata (dragonflies and damselflies).
Nymphs of aquatic insects, as in the Odonata, Ephemeroptera, and Plecoptera, are also called naiads, an Ancient Greek name for mythological water nymphs. In older literature, these were sometimes referred to as the heterometabolous insects, as their adult and immature stages live in different environments (terrestrial vs. aquatic).
In fly fishing with artificial flies, this stage of aquatic insects is the basis for an entire series of representative patterns for trout. They account for over half of the over all patterns regularly fished in the United States.
Nymph (Central Figure for "The Three Graces") is a bronze sculpture, by Aristide Maillol. It was modeled in 1930, and cast in 1953, it is at the Hirshhorn Museum and Sculpture Garden.
In the tradition of the Three Graces in Ancient Roman sculpture, and The Three Graces (sculpture), by Antonio Canova, it shows serenity, in contrast to his contemporary, Auguste Rodin.
