The Caucasus Pearl-Bordered Fritillary (Boloria euphrosyne dagestanica) is a butterfly in the Nymphalidae family – brush-footed butterflies. It is an insect.
The Caucasus Pearl-Bordered Fritillary is orange with black spots on the upperside of its wings. The underside of its wings has a row of silver-pearl markings along the edge. The caterpillars are black with white or yellow spines along their backs.
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 (the pupae stage) lasts for 10-14 days before adult butterflies emerge.
Adult butterflies feed on the nectar of flowers.
