Range In the United States, davisiHNS has been recorded from New York to North Carolina and northern Alabama. I have also identified a series collected by Stuart and Jarmila Kukalova-Peck from the Mesa de Chipinque Monterrey, Nuevo Leon, in northeastern Mexico. The species thus appears to have a disjunct distribution between the southeastern U.S. and northeastern Mexico, of the kind known in many other animal and plant species.
Biology In the eastern United States, davisiHNS is typically an inhabitant of pine barrens, where it has been found in crater nests constructed in open sandy areas exposed to the sun. Its habitat in Mexico is unknown. Colonies have been observed to harvest seeds (Stefan Cover).
