Is a firefly an example of incomplete metamorphosis?

No, a firefly is not an example of incomplete metamorphosis; it undergoes complete metamorphosis. This process includes four distinct life stages: egg, larva, pupa, and adult. Incomplete metamorphosis, on the other hand, involves three stages: egg, nymph, and adult, without a pupal stage. Fireflies belong to the order Coleoptera (beetles) and exhibit this complete metamorphic cycle.
