Its wingspan measures about 4 centimetres (1.5 inches).

The Caucasus Pearl-Bordered Fritillary is found in the Caucasus and Transcaucasia, in countries such as Georgia, Armenia, Azerbaijan, and southern Russia. It prefers grasslands and woodlands.

The female Caucasus Pearl-Bordered Fritillary lays eggs in leaf litter on the ground, or on leaves. The eggs are laid singly, not in a group or cluster. The eggs hatch after 10-14 days.

Caterpillars emerge from the eggs and begin feeding on plant leaves. The caterpillars moult (shed their skin) three times in 5-6 weeks, before hibernating in a chrysalis. The chrysalis stage lasts for 10-14 days before adult butterflies emerge.

Adult butterflies feed on the nectar of flowers.
