Abstract：Metamorphosis has allowed insects to become the most diverse and widely distributed land organisms. Metamorphosis is the biological process through which insect larvae develop into pupae and pupae develop into adults. It is divided into five types on the basis of the degree of morphological change that takes place, these types are; anamorphosis, epimorphosis, prometamorphosis, and incomplete and complete metamorphosis. Metamorphosis in insects is a complicated process that is accurately regulated by various factors, such as hormones, genes and nutrients. This review provides a brief description of the types of insect metamorphosis and their molecular regulatory mechanisms.
