I define metamorphosis as changes of the insects there are 2 kinds of metamorphosis there is complete metamorphosis that has 4 stages andthe incomplete metamorphosis that has only 3 stages Incomplete: egg = imago/nymph = adult Complete: egg = larva = pupa = adult Larva-the second stage among few insects with corresponding larval terms. *caterpillar- butterfly *maggot- fly *wriggler- mosquito Chrysalis- the protective covering of a butterfly. Imago- insect in its mature and its typically winged state. Pupa stage- stage by which the animal stays in its cocoon.
