Insect life cycles: complete metamorphosis
CONCEPTUALInsect life cycles — complete metamorphosis in detail. Egg → larva → pupa → adult. The larva (caterpillar, grub, maggot) looks completely different from the adult. Inside the pupa the body is rebuilt. Butterflies, beetles, flies, and ladybirds all undergo complete metamorphosis.
Mastery Evidence
- Name the four stages of complete metamorphosis using the correct terms: egg, larva, pupa, adult
- Explain that the larva stage is when the insect eats and grows, and the pupa stage is when its body transforms
- Give at least two examples of insects that undergo complete metamorphosis such as butterflies and beetles
Assessment Prompt
