The document outlines the 4 stages in the life cycle of a butterfly:
1) Egg stage - Eggs are laid on leaves and take 1-3 weeks to develop into caterpillars.
2) Caterpillar or larva stage - The caterpillar emerges from the egg and eats voraciously, shedding its skin several times as it grows.
3) Pupa stage - The caterpillar forms a cocoon and undergoes metamorphosis within, emerging after weeks or months as a butterfly.
4) Adult stage - The butterfly emerges from its cocoon with wings and a familiar form, living on average only a few weeks before the cycle repeats.
