com·plete met·a·mor·pho·sis

insect development from egg, through successive larval instars, pupa, and adult; the latter is distinct from the first two forms of the insect, permitting specialization of feeding (larval) and reproductive-flying functions (adult); characteristic of the higher insect orders, such as Coleoptera (beetles), Hymenoptera (bees, wasps, ants), Diptera (two-winged flies), and Siphonaptera (fleas).

complete metamorphosis

n.
A type of metamorphosis in which an insect passes through distinct egg, larval, pupal, and adult stages, and the larva does not resemble the adult. Also called holometabolism.

However, the action of thyroxine on neotenic salamander species (i.e., those that do not undergo metamorphosis and reproduce as Killed animals) has varied impacts, ranging from no effect to complete metamorphosis. In general, the variable effects of thyroxine on these neotenic salamanders result from a lack of cell-surface receptors for thyroxine.
