The color of the hindwings are orangish brown with a tan postmedian band followed by a row of round silver spots.

The median area with but one very regular row of dots in the middle, at the proximal side of which there are often feeble shadows in the female.

[7]It is found throughout the north-temperate region of the Northern Hemisphere[7] including the Balkan Mountains of Bulgaria and one isolated population in Serbia.

[5] Proclossiana eunomia exhibits a polygynous mating system which is quite common in butterflies with short breeding periods.

The butterfly Proclossiana eunomia wants to pass on as many genes as it can in its short lifespan and thus males do not discriminate, trying to court all females they encounter.

On the other hand, females are a bit more selective and have been observed to refuse incoming males either by displaying a mate-refusal posture or by simply fleeing away.

The polygynous mating system of the bog fritillary whereby males freely pursue females induces a change in migratory behavior.
