Countries Occupied

Number of countries occupied by this species based on AntWiki Regional Taxon Lists. In general, fewer countries occupied indicates a narrower range, while more countries indicates a more widespread species.


Estimated Abundance

Relative abundance based on number of AntMaps records per species (this species within the purple bar). Fewer records (to the left) indicates a less abundant/encountered species while more records (to the right) indicates more abundant/encountered species.



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.
