Chestnut tigers are large butterflies in the subfamily Danainae, family Nymphalidae, order Lepidoptera. Their forewings are 5 to 6 cm long. They are beautiful, with black veins on wings with a translucent light blue underside. The Japanese name “asagimadara” comes from the traditional color asagi, which is a blue-green. They are found all over Japan, the Korean Peninsula, China, Taiwan, and the Himalayas, and are known for traveling over 1,000 km depending on the season. In the spring, they travel northward from the Nansei Islands to Honshu. Their offspring stay in cool highland areas during the summer and travel southward in the fall again. Noto’s highest peak, Mt. Hodatsu (637 m) in Hodatsushimizu Town, is an important stopover for chestnut tigers. To monitor chestnut tigers, the marking of individual butterflies is carried out on Mt. Hodatsu every year. The chestnut tigers with marks are captured in various parts of Japan including Kikaijima Island, Kagoshima Prefecture.
