Boloria eunomia - Bog Fritillary - Ringoogparelmoervlinder - Randring-Perlmutterfalter
The uppersides are bright orange and the rounded post-discal spots of the forewing lie in an almost straight line, but the most obvious feature is the dark zig-zag line around the edge of each wing. This zig-zag is repeated on the undersides which are essentially pale orange with yellow borders. The underside of the hindwing has a bright-yellow band near the middle and an arc of dark rings with pale centres in the outer half. Flight June to July. The larval foodplant is Common Bistort.
