Types of Metamorphosis

Question 1

Sam watched three insects in his garden: 1. A caterpillar, the young of a butterfly, is soft, worm‑like and has no wings. 2. A young grasshopper is small, has the same body shape and legs as an adult, and only tiny wing buds. 3. A young beetle looks like a tiny beetle with a rounded body and tiny wing covers. Which statement correctly explains why the grasshopper young looks like a small adult while the caterpillar looks completely different from the butterfly adult?

Accepted Answer

Grasshoppers undergo incomplete metamorphosis, so their young are called nymphs that resemble miniature adults; butterflies undergo complete metamorphosis, so their young are larvae that look very different from the adult.

Answer

Both grasshoppers and butterflies have larvae, but grasshopper larvae retain adult features while butterfly larvae lose them during growth.

Answer

The appearance difference is due to where the eggs are laid – grasshopper eggs on leaves keep the young looking adult‑like, while butterfly eggs on flowers produce worm‑like young.

Answer

All insects start as larvae, but beetles change color later, making their young look different, whereas grasshoppers keep the same color, so they look like small adults.

Question 2

Which option correctly lists the life‑cycle stages in order for a June bug (which has complete metamorphosis) and a cicada (which has incomplete metamorphosis)?

Accepted Answer

June bug: egg → larva → pupa → adult; cicada: egg → nymph → adult

June bug: egg → pupa → larva → adult; cicada: egg → nymph → adult

Answer

June bug: egg → larva → adult; cicada: egg → nymph → pupa → adult

Answer

June bug: egg → larva → pupa → adult; cicada: egg → nymph → pupa → adult
