Hereditary and Reproduction. Meghann Bryant. Is the development after hatching of insects or animals from an immature stage to an adult stage. Insects can go through complete metamorphosis or incomplete metamorphosis depending on the species of insect. . What is Metamorphosis . Metamorphosis. is the transformation that occurs in the life cycle of many. arthropods . from egg through the larval and pupal stages to the adult form (. imago. ). . It also occurs in amphibians which turn from tadpoles into adults. . Art II. Media of Choice. What is Metamorphosis?. A change of physical form. Usually occurs during the process of when insects change their form from larva to pupa to imago. Frogs also go through metamorphosis from tadpole to frog. COMPLETE AND INCOMPLETE . METAMORPHOSIS.
