Insects are animals, they are living things that grow and reproduce
The life cycles of different insects can be observed over time and/or researched
The life cycle of an insect is commonly: egg, larva (young stage), pupa (inactive) and adult stage
Many insects undergo the greatest changes of all animals, they undergo a complete metamorphosis
Scientific diagrams are used to show the stages in an insect’s life cycle

Pupils may think that the insect is dead inside the pupa, or that the pupa is not a living thing.

Using the lesson resources to support, explain that the insect is alive and changing inside the pupa, even if the pupa itself doesn't move.

Insect - An insect is an invertebrate animal that has antennae, six legs and a body divided into segments.
Life cycle - A life cycle is the way in which a living thing changes as it ages.
Larva - Larva is the life cycle stage that some animals go through before metamorphosis into their next form.
Pupa - Inside a pupa, an insect changes from one form to another.
Metamorphosis - Metamorphosis is a major change from one form to another.
