## Activity 1

Write the next stage or developmental pattern requested in each row, using the lesson diagrams.

1. Butterfly: after egg
2. Butterfly: after larva
3. Butterfly: after pupa
4. Mosquito: developmental pattern
5. Mosquito: between larva and adult
6. Dragonfly: a pupa?
7. Dragonfly: developmental pattern
8. Cockroach: name of the young stage
9. Cricket: developmental pattern
10. Frog: larval name
11. Frog: fate of the tadpole tail
12. Diagram: eggs after adult

## Activity 2

1. What is the key evidence of complete insect metamorphosis?
2. Why discuss frogs separately?
3. Why might two diagrams have different picture counts?
4. Explain incomplete.
5. What should you write if a picture’s identity is uncertain?

3. Butterfly: after pupa: Adult
4. Mosquito: developmental pattern: Complete

6. Dragonfly: a pupa?: No
7. Dragonfly: developmental pattern: Incomplete
8. Cockroach: name of the young stage: Nymph
9. Cricket: developmental pattern: Incomplete
10. Frog: larval name: Tadpole
11. Frog: fate of the tadpole tail: Reabsorbed

- 1. A pupa between larva and adult.
- 2. Frogs are amphibians; tadpoles develop into frogs without a pupa.
- 3. One diagram may divide growth within a stage into several pictures. Check labels and sequence.
- 4. An insect developmental pattern without a pupa, not failed development.
- 5. Record it as uncertain and seek a labelled source; do not invent a name or stage.
