Taiwan is home to over 400 kinds of butterflies. We live on this island, so we should learn more about them. Nora: Then what did you learn from the video? Ethan: Each year, millions of purple crow butterflies fly across National Highway No. 3. Look! What an amazing sight! Nora: I've heard of this! When they cross the highway, many of them are killed by the traffic. Ethan: That's true. Now four-meter high nets are set up to stop these butterflies from entering the traffic flow. Nora: But where are the butterflies going? Ethan: They're going to the north, and in autumn, they will fly back to spend their winter in the south. John: Sounds interesting. I didn't know butterflies could live through the winter. Ethan: I'm planning a trip to see the butterflies. Want to join me? Nora: Sure. John: Count us in.
