DESCRIPTION

Reddish-orange ground colour on uppersides of wings, with black spots and veins. Silver markings on underside of rear wings.

Although similar in size and appearance to the Pearl-bordered Fritillary, the Small Pearl-bordered Fritillary has a later flight period, and can be distinguished by examining patterns on the rear wings.

The following illustrations compare the rear wing patterns of each species. These are reproduced from the leaflet "Learn about the Pearl-bordered Fritillary" published by Butterfly Conservation Scotland.

Wingspan 35 - 41mm (male), 38 - 44mm (female).
