Coordinator notes: Although identified as the Chryxus Arctic, this is probably Oeneis calais (presently a subspecies of chryxus). This arctic is found at higher elevations in the mountains (in excess of 9000 feet) and having a darker underside with less white scales in association with the median band is one character. The other you have to examine on the forewings and cannot be determined from photos. Chryxus flies only in even numbered years while calais flies every year at high altitude (more often above 10,000 feet and above timberline). Our calais is subspecies altacordillera Scott & Kondla.
