Ametabolous insect
Definition
An insect belonging to the group characterized by the absence of metamorphosis (Ametabola), in which the juvenile form (nymph) structurally resembles the adult almost perfectly, differing only in body size and the developmental stage of the reproductive system. As an adjective, it describes a species, a larva, or a direct biological development, characteristic of lower apterygote insects, such as the silverfish (Lepisma saccharina) or the order Thysanura.
