Insect Life Cycles: Complete and Incomplete Metamorphosis

Use the words egg, larva, pupa, nymph, adult and metamorphosis in your answers.

Part A: Two kinds of life cycle

Read the passage. Then circle the best answer.

All insects begin life as an egg, but they grow up in two different ways. Big changes in body shape during a life cycle are called metamorphosis.

Complete metamorphosis has four stages: egg → larva → pupa → adult. The larva looks nothing like the adult. It eats and grows, then forms a pupa. Inside the pupa its body changes completely. Butterflies, moths, beetles, flies, bees and ants all grow this way.

Incomplete metamorphosis has three stages: egg → nymph → adult. A nymph looks like a small adult without full wings. It grows by moulting — shedding its hard outer skin — several times. Grasshoppers, crickets, cockroaches and dragonflies grow this way.

Some young insects live in a different place from the adults. Dragonfly nymphs and mosquito larvae live in water, but the adults fly in the air.

1.What is the correct order for complete metamorphosis?
  1. Aegg → pupa → larva → adult
  2. Begg → larva → pupa → adult
  3. Clarva → egg → adult → pupa
  4. Degg → nymph → adult

  1. Acaterpillar
  2. Bnymph
  3. Ctadpole
  4. Dmaggot
3.Which insect goes through incomplete metamorphosis?
  1. Aa butterfly
  2. Ba beetle
  3. Ca grasshopper
  4. Da bee
4.What happens inside the pupa?
  1. AThe insect lays eggs.
  2. BThe insect eats lots of leaves.
  3. CThe insect hatches from an egg.
  4. DThe insect's body changes into the adult form.
5.Why does a nymph moult?
  1. AIts hard outer skin cannot stretch as it grows.
  2. BIt is too cold.
  3. CIt wants to change colour.
  4. DIt is turning into a pupa.

Part B: Stages and names

6.Match each insect to the name of its young.
  • butterfly

10.A caterpillar and a butterfly are the same insect at different stages. ☐ True   ☐ False
11.A grasshopper nymph has to become a pupa before it is an adult. ☐ True   ☐ False
