Great Arctic, Nevada Arctic, Great Grayling, Felder's Arctic, Pacific Arctic: Oeneis nevadensis

A great arctic observed nectaring on the flowers of glaucous penstemon (Penstemon euglaucus) along the Shorthorn Trail about one-half mile above the trailhead at Morrison Creek Camp, Mt. Adams Wilderness.....July 7, 2021.

This photo shows the upper and lower wings of a great arctic as seen along the Island Springs Trail #66 atop the Island, a ridge on the eastern slopes of Mt. Adams.........August 12, 2006. Both the upper and lower surfaces of the forewing bear two eyespots, partially visible in these photos.

This photo shows a great arctic hiding amongst grasses. Because of the grayish-brown coloration of the underwings, this butterfly is very hard to see before they dart into the air to avoid being stepped on. They then fly strongly away, often landing amongst grass or on downed logs where they again escape detection. They can be seen early in May on the southeastern flanks of Mt. Adams until late August at higher elevations.

These photos show the colorful under surface of the wings of a great arctic as seen along the Willard Springs Trail in Conboy Lake NWR.........June 15, 2008.
