Compare two species

Southwestern Fence Lizard vs. Plateau Fence Lizard

Split on genetics in 2002 and nearly identical to the eye: the Southwestern Fence Lizard lives in eastern and southeastern Arizona, the Plateau Fence Lizard in the north and west; they meet in east-central Arizona. A: East and southeast: the White Mountains south to the Chiricahuas in the Southwestern Fence Lizard; north and west: the Colorado Plateau, the Mogollon Rim and westward in the Plateau Fence Lizard. Their looks overlap completely (both have two pale stripes, a grey middle stripe and, in males, blue belly patches edged black). RANGE IS THE SUREST WAY TO TELL THEM APART.
