This pretty yellow rat snake is from southcentral Florida.
Although the range of the yellow rat snake, Pantherophis obsoletus quadrivittatus, extends far north of FL, let’s just take a quick look at some of the color variations of this pretty constrictor in the Sunshine State. Generally speaking, the snake is least colorful (olive yellow) in northcentral FL and most richly hued (bright yellow) in seFL. The keywords in the last sentence are “generally speaking” for variations within any geographic area are not only possible but should be expected.

Just as the ground color varies from north to south, so, too, does the color, thickness, and intensity, of the four dark stripes that provide the alternate name of “four-lined rat snake” for this subspecies. The stripes may be black, brown, buff, or orange. Thickest and darkest in ncFL, the lines may be well defined or barely visible in central FL and very poorly defined in the seFL. But again, let me emphasize, variation is the rule of thumb. One of the prettiest and most precisely striped yellow rat snakes I have seen in recent times has been from Polk County—right on the heart of the peninsula.

And now that I’m thinking about yellows, I guess I’ll head to Polk County in the AM!
