We often see them flying among flowers in warm seasons. A butterfly goes through four stages in its life. First, the butterfly lays eggs on leaves. Soon caterpillars hatch. They eat leaves non-stop to grow. Later, they build a chrysalis. Inside it, great changes take place. At last, an adult butterfly comes out. It has to wait until its wings get hard before flying. Butterflies feed on nectar from flowers. Their bright wings are not just pretty. Some look like dry leaves so birds cannot easily find them. Besides, butterflies help plants grow. They carry pollen between flowers. Now many butterflies are in trouble. Their living places are disappearing. If we plant more native flowers, we can offer butterflies a safe home. 1.

They play an important part in nature. Bees do pollination when they fly from flower to flower. About 80 percent of plants need bees to grow. Without bees, we can hardly get many fruits and vegetables. However, the number of bees is dropping these days. They are facing great danger. We must do something to protect them. We can plant more flowers and stop using too much pesticide. We should also tell our family and friends how important bees are. People, plants and animals are all connected. Let’s take action to save bees. 学科网（北京）股份有限公司 $
