Life Cycle of the Butterfly

Few things enchant children more than watching a caterpillar become a butterfly. The transformation is lived, not told. A caterpillar that doesn't form a chrysalis shows something wrong — the control is biological reality.

• Framework: Montessori
• Unit: Cultural Studies
• Learning area: Zoology
• Level: Ages 6-7

Objectives

• Identify and order the four stages of butterfly life: egg, caterpillar (larva), chrysalis (pupa), adult
• Raise butterflies in the classroom
• Compare to other insect life cycles (complete and incomplete metamorphosis)
• Release butterflies back to nature

Materials

• Life cycle diagram cards
• Live butterfly rearing kit (painted lady or monarch)
• Host plants for feeding
• Journal for observations

Instructions

1. Set up the rearing container. 2. Add caterpillars with host plants. 3. Observe daily: note eating, size, color. 4. Caterpillars molt several times. 5. Each forms a chrysalis — describe its color and shape. 6. Wait 10-14 days. 7. Adult emerges, wings expand. 8. Observe wing patterns, body parts. 9. Release outside where host plants grow.

Educator tip

The release is joyful and communal. Let each child hold a butterfly on their finger before it flies. Photograph everything.

Assessment

Note observation depth in journal, sequencing of stages, and understanding of metamorphosis.
