Overview
The child learns the four stages of complete metamorphosis — egg, larva (caterpillar), pupa (chrysalis), and adult (butterfly) — using figurines, nomenclature cards, and ideally a live butterfly kit for ongoing observation.
Objectives
What the child gains from this work
Name and sequence the four stages of butterfly metamorphosis: egg, larva, pupa, adult. Understand that metamorphosis means a complete change in form. Develop vocabulary: metamorphosis, larva, chrysalis, pupa, antennae, proboscis, thorax. Connect the life cycle concept to other organisms (frog, mealworm). Practice sequencing and cyclical thinking.
Materials Needed
Gather these before presenting
- Life cycle figurine set (4 stages: egg, larva, pupa, adult)
- Nomenclature three-part cards for each stage
- Circular life cycle mat or chart with arrows
- Magnifying glass
- Drawing paper and colored pencils
Presentation
Follow this sequence during your presentation
- Invite the children to the mat; show a picture or figurine of a butterfly and ask: "Do you know how a butterfly begins its life?"
- Place the circular life cycle mat in the center; explain that life goes in a cycle — a circle with no true end.
- Present the egg figurine: "The mother butterfly lays a tiny egg on a leaf. Inside the egg, a new life is growing." Place at the top of the cycle.
- Present the larva figurine: "From the egg hatches a caterpillar — scientists call it a larva. The caterpillar eats and eats and grows bigger." Place at the next position.
- Present the pupa figurine: "When the caterpillar is big enough, it forms a chrysalis around itself — this stage is called the pupa. Inside, an amazing change is happening." Place at the next position.
- Present the adult butterfly figurine: "After many days, the chrysalis opens and out comes a butterfly! This is the adult." Place at the final position, connecting back to the egg.
- Trace the cycle with your finger: "Egg, larva, pupa, adult — and then the adult lays eggs, and the cycle begins again."
- Conduct a Three-Period Lesson with the four stage names.
- Invite children to sequence the figurines independently on the mat.
- If a live kit is available, introduce it: show the current stage of the real caterpillars and connect to the model.
- Offer drawing paper for children to illustrate their own life cycle diagram.

Extensions
Where to go when the child is ready for more
Maintain a live butterfly habitat and journal observations daily until release. Compare butterfly metamorphosis to frog metamorphosis (egg, tadpole, froglet, frog). Research different butterfly species and their host plants. Create a life cycle wheel that children can spin through the stages.

Points of Interest
For younger children (3-4), simplify to "caterpillar becomes butterfly" with two-stage emphasis. For elementary children (6+), introduce incomplete metamorphosis (grasshopper) for comparison.
