    Butterflies start out as eggs. Butterflies lay their eggs on leaves. The egg hatches into a caterpillar with a tube-shaped body. The caterpillar eats leaves, buds, or flowers of plants. Caterpillars eat a lot and grow fast. Some caterpillars harm plants.

    When a caterpillar is full size, it goes into another stage called a 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 butterflies 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 dry and harden. The beautiful butterfly then flies off to slurpnectar from flowers. Most butterflies live only one or two weeks.
