The pearl-bordered fritillary (''Boloria euphrosyne'') is a butterfly of the Nymphalidae family found in Europe and northern Asia. == Description == It is orange with black spots on the upper side of its wing and has a wingspan of 38–46 mm. On the underside of the wings there is a row of silver pearly markings along the edge, which give the species its name. It is often confused with the small pearl-bordered fritillary, but can be distinguished from it by the triangle along its pearl-border (the small pearl-bordered has black chevrons) as well as the presence of a single silver spot in the middle of a row of yellow spots. The female has both darker markings and rounder wings than the male. The caterpillars are black with white or yellow spines along their backs. Like other species of fritillary, the males have special scent glands on their wings so that they can be recognised by females of their own species and therefore find a suitable partner.
