Argynnis sagana is a species of butterfly in the family Nymphalidae.
Description Argynnis sagana has a wingspan of about . 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 mistakenly attributed to different species.
The caterpillars are dark brown, with long yellowish appendages similar to thorns.
Biology This butterfly has a single brood and flies from July to September depending on the location. They feed on Viola species (Viola grypoceras, Viola verecunda, Viola eizanensis, Viola uniflora).
Distribution and habitat This species is present in broadleaves or mixed light forests of China, Mongolia, South Eastern Siberia, Korea and Japan.
