FACTS
Metamorphosis refers to the way that certain organisms develop, grow, and change form.
Metamorphosis actually means "change".
Metamorphosis has 2 types: complete and incomplete
Complete metamorphosis has 4 stages (egg, larva, pupa, adult) while incomplete metamorphosis has 3 stages (egg, nymph, adult)
To take a closer look at these 2 types of metamorphosis, check out these two websites:

FACTS
A female insect lays eggs. These eggs are often covered by an egg case which protects the eggs and holds them together.
Nymphs looks like small adults, but usually don't have wings
.
Most nymphs molt 4-8 times.

Larva hatch from the eggs. They do not look like adult insects. They usually have a worm-like shape.
Caterpillars, maggots, and grubs are all just the larval stages of insects. Larvae molt their skin several times and they grow slightly larger.
Take a look at this website for more about the differences between complete and incomplete metamorphosis:
