After hatching as a larva, the insect undergoes successive larval molts until a metamor- phic molt causes it to enter the pupal stage.
Then an imaginal molt turns it into an adult that ecloses from the pupal case with a'new cuticle.
Eventually, an imaginal molt forms the adult (imago) cuticle beneath the pupal cuticle, and then the adult later emerge from the pupal case at adult eclosion.
In holometabolous insects, the transformation from juvenile into adult occurs within the pupal cuticle.
During the pupal stage, these cells give rise to the muscles and nerves that serve the legs.
