A small insect of the Hesperiidae family of the Lepidoptera order. It is a small species with a span of 2.5 to 3 cm. Its base color is dark brown, and its name comes from the fine white spots scattered all over it. It is distributed through Myanmar, northern China, the Amur region, and the Korean Peninsula to Japan, and can be seen in the mountainous areas of Hokkaido, Honshu, and Shikoku, but its distribution is narrow and limited. It emerges twice a year, with the spring type emerging from late April to mid-May and the summer type emerging from late July to mid-August. The summer type is larger than the spring type, and the white spots are smaller. It lives in dry grasslands, and is often seen in the foothills of volcanoes.
