What is the key difference between complete metamorphosis and incomplete metamorphosis in insects?
AIncomplete metamorphosis always takes much longer overall than complete metamorphosis
BComplete metamorphosis only occurs in aquatic insects
CThere is no meaningful difference between the two processes
DComplete metamorphosis includes a distinct pupal stage with a dramatic body transformation, while incomplete metamorphosis does not include this distinct pupal stage
Explanation
Complete metamorphosis involves four distinct life stages, egg, larva, pupa, and adult, with a dramatic body transformation occurring during the relatively inactive pupal stage, as seen in the transformation of a caterpillar into a butterfly. Incomplete metamorphosis, by contrast, involves three stages, egg, nymph, and adult, without a distinct pupal stage, with the young nymph instead gradually developing more adult-like features through a series of progressive molts. Insects like grasshoppers typically undergo incomplete metamorphosis, while insects like beetles and moths typically undergo complete metamorphosis.
