Which life cycle pattern describes insects with incomplete metamorphosis?

Which life cycle pattern describes insects with incomplete metamorphosis?

• A. Egg -> Nymph -> Adult
• B. Egg -> Larva -> Pupa -> Adult
• C. Egg -> Juvenile -> Adult
• D. Egg -> Fry -> Juvenile -> Adult

Answer: (A)

Incomplete metamorphosis describes insects that hatch from eggs into nymphs, which resemble smaller versions of the adults and molt through several stages until they reach the adult form. There is no pupal stage, so development stays fairly similar in body plan from nymph to adult. The sequence Egg -> Nymph -> Adult matches this pattern, because each molt brings the insect closer to the final adult form without a distinct larval-pupal transition. Insects with complete metamorphosis—such as butterflies, beetles, and bees—go through a larva and a pupal stage before becoming adults, which is why that option isn’t the correct description here. The other sequences include nonstandard terms like “juvenile” or “fry,” which aren’t used in describing insect development.
