Biology A colony found in Hidalgo County, New Mexico, by Stefan Cover (unpublished field notes) was in open desert with scattered mesquite, yucca, and Ephedra, occupying a soil nest with an entrance in a grass clump. A second colony was discovered by Cover nesting in open soil near Pecos, Texas, in saline desert among growth of Limonium and Salicornia. Nests reported by Moody and Francke (1982) in western Texas were at 600 to 1700 m and variously under stones and in open soil.
