pupa
Let an agent explain the pupal stage and its biology and variants, describe how pupae form and what happens inside them, support identification and rearing, and support learning about metamorphosis.
Research draft, second pass
A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description
Let an agent explain the pupal stage and its biology and variants, describe how pupae form and what happens inside them, support identification and rearing, and support learning about metamorphosis.
The life stage of insects undergoing complete metamorphosis between larva and adult, during which the insect does not feed and its body is reorganised into the adult form, protected in some species by a cocoon or, in flies, by a hardened puparium formed from the last larval skin, and in butterflies known as a chrysalis; the pupal stage varies from days to months and is a period of vulnerability, dormancy and transformation studied in developmental biology.
What it is for: Transformation stage between larva and adult insect.
It can be explain biology and variants; describe transformation; support identification and rearing; support learning.
Distinguishing features
Non-feeding
Body reorganisation
Protective coverings
Variable duration
What it looks like
Immobile stage, often in a cocoon, chrysalis or puparium.
How it is recognised
Non-feeding stage between larva and adult
Cocoon, chrysalis or puparium
Nymphs of incomplete metamorphosis have no pupal stage; eggs precede larvae
