Of the hundreds of migrating Blue Tiger butterflies, 26 of them were discovered to have flown across the ocean from Japan to Taiwan, according to the team led by Chen Chien-chih (陳建志), director of the University of Taipei’s Department of Earth and Life Science.

The butterflies, discovered at forts in Siyu Township in Penghu, traveled as far as 2,509 km from Japan’s Fukushima Prefecture.

A volunteer named Hsu Tzu-yu (許自由) found this year’s first Blue Tiger butterfly that migrated from Japan to Penghu in Siyu on Oct. 23, with information marked on its wings, Chen said.

The butterfly, with bluish-white spots and streaks on its brown wings, was released from Japan’s Tokushima Prefecture.
