A nymph represents a transitional developmental stage observed in certain classes of insects. This phase occurs after the embryonic period and precedes the final adult molt, functioning as a juvenile form of the species. Growth during the nymph stage is achieved through a process of gradual exoskeleton shedding, known as molting. The physical appearance and biological characteristics of the nymph often resemble miniature versions of the adult, though they typically lack fully developed adult reproductive structures and may display distinct morphological differences that reflect their immaturity.
