What is the correct order of stages in incomplete metamorphosis in insects?
- AEgg – Larva – Pupa – Adult
- BEgg – Larva – Adult
- CEgg – Nymph – Pupa – Adult
- DEgg – Nymph – Adult
Show answer and explanation
Correct answer: (d) Egg – Nymph – Adult
Explanation
In incomplete metamorphosis (hemimetabolous development), an insect develops in three stages: egg → nymph → adult. There is no larva and no pupa. The nymph looks like a small adult without fully grown wings or reproductive organs and becomes an adult through several moults.
Examples: cockroach, grasshopper, termite, dragonfly. In complete metamorphosis, there are four stages: egg → larva → pupa → adult, as in the butterfly, housefly and mosquito.
