Female monarch butterflies can lay one hundred eggs on one plant. Caterpillars drink milkweed to help them live and hatch out of their cocoons to turn into a beautiful Monarch butterfly. Monarch has 4 stages in their life cycle but most people think they have two. Butterflies start out as a egg (caterpillar), then hatch into larvae (a caterpillar), and then wrap up in the cocoon, and then they go through the metamorphosis into a butterfly while they are in the cocoon.
