Butterflies
Have you ever seen a butterfly flutter by? Have you looked at its colorful wings? Have you watched it land on flowers? Read on to learn about this amazing insect.
A butterfly does not begin its llife cycle as a butterfly. First, there's an egg. When the egg hatches, a caterpillar comes out. The cateroullar eats and eats and eats. Soon it grows large.
When the caterpillar's big enough, it hangs from a branch. Then it changes into a chrysalis. The chrysalis will develop into a butterfly.
After about two weeks, the waiting is done. The chrysalis has developed into a butterfly. The butterfly pushes out of its old skin. It shivers because its wings are wet. It rests in the sun and waits for its wings to dry.
Once its wings are dry, the butterfly flies off to find food. Many butterflies eat nectar, the sweet juice made by flowers. With its long tongue, a butterfly can suck nectar out of the middle of flowers.
