  • In May and June, thousands of chestnut tiger butterflies can be found in Yangmingshan.

  • But by July, most of them are gone.

  • Where do they go?

  • To find the answer, Li Xinde, a student from National Taiwan University, marked four thousand butterflies in June 2000 to track them.

  • Later in July, one of them was caught by a man in Japan.

  • He noticed the butterfly was marked with numbers and letters.

  • After taking a picture of the butterfly and posting it on the Net, the man was told that the butterfly came from Taiwan.

  • The news surprised a lot of people because very few knew that butterflies could fly across the ocean like some wild geese.

  • More exciting news came after Li's study.

  • In November 2001, a chestnut tiger butterfly with the mark "SOA118" was collected in Pingtung.

  • The butterfly was marked and released from Osaka, Japan.

  • It flew almost 2,300 kilometers from Japan to Taiwan.

  • Many scientists were excited about the news because it showed that chestnut tiger butterflies also fly from Japan to Taiwan.

  • How far can chestnut tiger butterflies travel?

  • Why do they fly across the ocean?

  • Today, scientists are still studying them to find out the answers to these questions and more.

In May and June, thousands of chestnut tiger butterflies can be found in Yangmingshan.
