Butterflies are some of the most beautiful insects on Earth. They can be found on every continent except Antarctica. There are about 20,000 different species of butterflies!
A butterfly goes through four stages called metamorphosis. First, a butterfly lays an egg on a leaf. The egg hatches into a caterpillar. The caterpillar eats and grows, then forms a chrysalis. Finally, an adult butterfly comes out!

Butterflies help plants by spreading pollen from flower to flower. They are also an important food source for birds and other animals.
