Butterflies are a type of insect with large and often colorful wings. They start out as eggs. They lay their eggs on leaves. The eggs hatch into caterpillars with tubular body. The caterpillar eats leaves. buds, or flowers of plants.

    When a caterpillar is full sized, it goes into another stage called chrysalis. Caterpillars attach themselves to something solid before becoming a chrysalis. The caterpillar inside the chrysalis changes into a butterfly. Some butterflies make the change in one week. Some others take years to change.

     When the change is complete, the adult butterfly splits the chrysalis. The insect unfolds its wings and pumps blood and air into them. It spreads out the wings until they become dry and harder. The beautiful butterfly the flies to get nectar from flowers. Most butterflies live only for one or two weeks.
