The Coppers are a subfamily of the Gossamer-winged butterflies and in Finland are represented by five species. The scarce copper is common in Finland and can be easily differentiated from other coppers by the white blotches on the underside of its wings. Males lack the clear black central blotch on the forewings that is typical of the large copper. Females have a row of black blotches along the margin of their hind wings which do not feature on the large copper. The purple-edged copper can be identified by the orange veins on the upper side of scarce copper’s hind wing.
Males wait for females in their territories, which they defend on the edges of forests. Females lay their eggs individually or in small bunches on the leaves of the host plant.
