Argynnis sagana is a butterfly of the Nymphalidae family.
Argynnis sagana has a wingspan of about 50–60 millimetres (2.0–2.4 in). This species displays little geographical variations, but it is well known for the significant differences (sexual dimorphism) between males (orange-brown wings with black markings) and females (dark brown or black wings with white bands), so individuals of different sexes can be easily attributed to different species. Males of Argynnis sagana are sometimes treated as Damora sagana.
This butterfly has a single brood and flies from July to September depending on the location. The larvae are dark brown, with long yellowish appendages similar to thorns. They feed on Viola species (Viola grypoceras, Viola verecunda, Viola eizanensis, Viola uniflora).
This species is present in broadleaves or mixed light forests of China, Mongolia, South Eastern Siberia, Korea and Japan.
