Cicadas have incomplete metamorphosis. Insects with complete metamorphosis have four life stages: egg, larva, pupa, and adult. Insects with incomplete metamorphosis, including cicadas, do not have a pupal stage, and the immature form is called a nymph.
I don't know too many insects that go through a complete metamorphosis, but I know that a fly, butterfly, moth, beetle, ants, bees, ladybugs and cockroach . Just a fun fact: about 88% of insects go through a complete metamorphosis.
