Erebia occulta is resident in Alaska, where it is present in three separate populations (Scott 1986). Habitats are arctic/alpine zone dry rocky places, preferably areas with small rocks rather than massive boulder scree. There is one flight each year with the approximate flight time June 15-July 15; this species is possibly biennial (Scott 1986).
