Identification:
Both sexes are uniformly dark chocolate brown above with a broad contrasting white border. And the female has a few diffuse orange spots near the corner of the hindwing. The underside is dark beige-brown with a diffuse coloration. This being mainly a typical submarginal band with orange spots on the hindwing and a a row of black white encircled spots within this band and a long white wedge running from the middle of the band to the white and black discal spot. Can vary in width and rarely be missing. Diffuse green-blue powdering can be present close to the body.

The combination of the upper- and underside should make it unique in the Nordic region.

Comment:
The only Danish record from Jylland 1997 has been disputed and by the gang around danske-natur.dk been removed from the official country list. I can't find any official Danish authority maintaining the list, why I'm keeping the species in the list, until I understand the lepidopteran community better...seems more Wild West than the ditto birding community!
