Endemic to a small area in Arizona, where it is restricted to a specific, gravelly soil type. Gravel quarrying has destroyed as much as one-fourth of the potential habitat in the area. There may be less than 1000 individuals left in the wild, and these are sought by collectors and threatened by off-road vehicle use, urban development, continued gravel pit mining operations, grazing, climate change (drought), and possibly new energy development such as wind energy.
