Distribution and Habitat
S. multiplicata ranges from western Oklahoma to Arizona (Arizona, New Mexico, Utah, Colorado, and Texas) and far south into Mexico (Conant and Collins 1991).
S. multiplicata can be found in various habitats, including grasslands, sagebrush flats, semi-arid shrublands, river valleys, and agricultural lands. It is sometimes found on roads following summer thundershowers (Degenhardt et al. 1996).
