What really happens inside a butterfly chrysalis?
Inside the shell, the caterpillar melts down into a rich soup. Tiny parts that survive the melting use this soup to build a brand new body with bright wings and long legs. After weeks pass and the shell turns clear, the shell cracks open and a butterfly emerges.
