This butterfly belongs to the order Lepidoptera, family Nymphalidae. It is an alpine butterfly found in the mountains of Hokkaido Daisetsuzan mountain range, which are about 1,800 meters or higher, and is designated as a national natural monument. Outside of Japan, it is found in cold regions around the Arctic, such as the Greater Xing'an Mountains in northeastern China, northern Siberia, Lapland, Scandinavia, Alaska, Canada, and the mountains of North America, and is known as a circumpolar species. It is the smallest of the Japanese fritillary butterflies. Its wingspan is about 35 mm. It appears once a year, usually from early July to mid-August, with the peak season being mid- to late July. On fine days, it flies low to the ground and swarms over flower fields, but disappears as soon as the sun goes down. The food plants of its larvae are the Chinese lantern plant (Coleoptera lanuginosa), the yellow rhododendron (Ericaceae), and the Japanese black bean tree (Rhododendron nigra). In Japan, there are two closely related species of this species, the Sakhalin Leopard Swallowtail and the Narrow-leaved Leopard Swallowtail, both of which are found in Hokkaido.
