The caterpillars eat lots of leaves and plants and grow bigger and bigger. Then, their skin starts to harden around them, forming a chrysalis. Inside the chrysalis, the caterpillars body changes quickly. It is wet and its wings are all wrinkled. The butterfly stretches out its wings and then stays very still for a few hours.
Butterflies fly very well, and can change directions easily.
They can land quickly. Their wings are made of many little scales. They use their proboscis to suck the nectar from flowers. It is a long tube that looks like a tongue. When they aren t eating, they roll up their proboscis.
