Question types: Insect metamorphosis

Rule: Insects

Complete metamorphosis: egg → larva → pupa → adult (butterfly, beetle, bee, fly).

Incomplete metamorphosis has no pupa: egg → nymph → adult (grasshopper, dragonfly, cockroach).

Example: A caterpillar is the larva of a butterfly; between them comes the pupa.

Watch out: A dragonfly nymph lives in water and never makes a pupa: dragonflies have incomplete metamorphosis.

Sample questions

  1. Question 1 Easy

    Which of these insects goes through incomplete metamorphosis (no pupa stage)?

    1. A) peacock butterfly
    2. B) ant
    3. C) housefly
    4. D) mosquito
    5. E) cockroach
    Show the solution
    Answer: E) cockroach

    How it works: peacock butterfly – complete metamorphosis (with a pupa); ant – complete metamorphosis (with a pupa); housefly – complete metamorphosis (with a pupa); mosquito – complete metamorphosis (with a pupa); cockroach – incomplete metamorphosis (no pupa)

  2. Question 2 Normal

    Which of these insects goes through complete metamorphosis (egg – larva – pupa – adult)?

    1. A) mosquito
    2. B) mayfly
    3. C) grasshopper
    4. D) locust
    5. E) firebug
    Show the solution
    Answer: A) mosquito

    How it works: mosquito – complete metamorphosis (with a pupa); mayfly – incomplete metamorphosis (no pupa); grasshopper – incomplete metamorphosis (no pupa); locust – incomplete metamorphosis (no pupa); firebug – incomplete metamorphosis (no pupa)

  3. Question 3 Hard

    Which of these insects goes through incomplete metamorphosis (no pupa stage)?

    1. A) peacock butterfly
    2. B) housefly
    3. C) mayfly
    4. D) mosquito
    5. E) seven-spot ladybird
    Show the solution
    Answer: C) mayfly

    How it works: peacock butterfly – complete metamorphosis (with a pupa); housefly – complete metamorphosis (with a pupa); mayfly – incomplete metamorphosis (no pupa); mosquito – complete metamorphosis (with a pupa); seven-spot ladybird – complete metamorphosis (with a pupa)
