Biology

Nevada, Wheeler and Wheeler (1986):

This species is found in abundance throughout the state from 4,300 ft. to 10,800 ft. (43% of the records 6,000-7,000 ft., 65% 6,000-8,000 ft., 93% 5,000-9,000 ft.). We have 204 records from 108 localities. Of these 64 were in the Cool Desert (2 in the cottonwood riparian), 51 in the Pinyon-Juniper Biome, 19 in the Coniferous Forest Biome, 8 from the ecotone above, and 5 in the Alpine Biome.

We have descriptions of 122 nests: 61 were under stones and 9 were under other objects lying on the ground; of the exposed nests 44 were surmounted by craters (4-10 cm in diameter with entrances 4-8 mm in diameter) and 8 by messy mounds of excavated soil. Colonies may be locally very numerous. Workers were timid and fast.

We have collected mealybugs from 3 nests (Homoptera: Pseudococcidae; det. D.R. Miller): Cryptoripersia tubulata McKenzie from Lamoille Canyon (9-32N-58) 7,000 ft. (Elko Co.) and from Mt. Jefferson 8,700 ft. (Nye Co.); Phenacoccus eschscholziae McKenzie from Carroll Summit (9-16N-38) 7,500 ft. (Lander Co.).

Fungi

This species is a host for the ectoparastic fungus Laboulbenia formicarum (Espadaler & Santamaria, 2012).
