During complete metamorphosis the egg hatches into basically a worm-like form termed a larva. This stage lasts a few to several instars, increasing in size and sometimes changing color or other characters. After the molt of the last instar the insect changes to a pupa. When the insect emerges from the pupal state it is an adult. Although in many cases some coloration and minor maturation of features occurs the insect does not molt or grow further during its life.
