The Life Cycle of a Butterfly

The butterfly starts its life as a small egg.

After hatching, the egg matures into a healthy caterpillar.

After growing to full size, the caterpillar turns into a pupa.

The caterpillar evolves for about two weeks inside the cocoon.

After two weeks, the butterfly will finally be ready to fly off!
