Biology
Nevada, Wheeler and Wheeler (1986) - We have 7 records from 6 localities: 6,000-7,800 ft. The 4 reported habitats were in the Coniferous Forest Biome. One nest was in a decaying pine stump; 1 was in firewood; 1 was in a house. The records are widely scattered except for a concentration near Lake Tahoe.
