The Life of a Butterfly can be summarized in 3 sentences: The cycle of stages a butterfly goes through is called metamorphosis, starting as an egg laid by the female butterfly, then hatching as a caterpillar that molts and eats voraciously, before forming a pupa and emerging as a butterfly with fully formed wings.

- 1. The Life of a Butterfly
- 2. The cycle of stages is called metamorphosis Stage One- Egg Butterfly and moth eggs are very small and round, oval or cylindrical. Many have ribs or other tiny features. Females lay their eggs on or near the plants that will later become caterpillar food.
- 3. Stage Two- Larva The larva hatches from the egg. Butterfly and moth larvae are usually called caterpillars. Caterpillars spend most of their time eating. A caterpillar's exoskeleton can't stretch or grow, so the caterpillar sheds its skin, or molts, several times as it grows.
- 4. Stage Three- Pupa When a caterpillar has finished growing, it forms a pupa. Every part of the caterpillar is changing at this time as it transforms into a butterfly. Butterfly pupae are called chrysalises.
- 5. Stage Four- Butterfly When the pupa has finished changing, it molts one last time and emerges as a butterfly or moth. It emerges with its wings folded up against its body. The butterfly or moth pumps blood into the wings to expand them. This is the stage when butterflies and moths mate and reproduce.
