Remarks
"This is the most variable species of the genus, and, although there seem to be geographical differences in norms, the whole gamut of variation is represented in most parts of the range. There is a high proportion of specimens with small spots in Texas, and of pale specimens in Arizona, but there is nothing approaching a degree of differentiation that would justify the separation of subspecies. I can see no clear seasonal separation between pale and dark individuals" (Munroe, 1956) (1)
