Biology
Nevada, Wheeler and Wheeler (1986) - We have 22 records from 17 widely scattered localities (4,100-6,200 ft.) but none in the northeastern quarter nor along the western border. Three were in the Pinyon-Juniper Biome and 12 in the Cool Desert (3 in Sarcobatus Subclimax, 3 in Atriplex Subclimax, 1 on a revegetating playa, 1 from a disturbed habitat). Six nests were under half-buried stones; 9 were surmounted by craters 5-10 cm in diameter.
