Lethe diana

The Lethe diana's wingspan ranges from 45 to 55 mm. Its forewings are dark brown, and sometimes have white belt-like patterns that are more apparent on the female. The hindwings are also dark brown with an eyespot pattern adorning the back, with about one or two small eyespots and on the forewings, and six eyespots ranging in size on the hindwing. The veins are a distinctly noticeable darker brown.

The Lethe diana can be found in regions of Russia such as Primorye, Sakhalin and South Kuril.[2] Regions of Japan such as Hokkaido, Honshu, Shikoku, Kyushu and Tsushima.[1]

Lethe diana can be found in deciduous forests from flatlands and mountains.[1]
