California's Mojave Desert is one of the locations of occurrence of this species. Some of the common flora associates are Spiny mendora, Mendora spinescens; Desert senna, Cassia armata; and Mojave dalea, Psorothamnus arborescens. Example cacti associates in this desert are: Silver cholla, Opuntia echinocarpa; Mojave prickly pear, O. erinacea; Beavertail cactus, O. basilaris; and Many-headed barrel cactus, Echinocactus polycephalus. The chief megaflora of this desert region is the Joshua tree, Yucca brevifolia. Soils here in the Mojave are mainly coarse sands and gravels with many outcrops that offer diverse habitat niches.
