Detailed explanation-1: -Complete and incomplete metamorphosis are two types of growth forms in insects. The complete metamorphosis occurs through four stages: egg, larva, pupa, and adult. The incomplete metamorphosis occurs through three stages: egg, nymph, and adult. The pupa stage is not developed during incomplete metamorphosis.

Detailed explanation-2: -The life cycle of holometabolous insects (those which undergo complete metamorphosis) includes four distinct stages: egg, larva (caterpillar), pupa (chrysalis) and adult.

Detailed explanation-3: -The first stage of incomplete metamorphosis is the egg. During this time, the insect will hatch into a form called a nymph. The nymph is basically a small version of the adult insect. This is very similar to how a child looks like his or her parents.

Detailed explanation-4: -Nymph: The immature form of insects with simple metamorphosis. (Stages between molts of the exoskeleton are called instars).
