The Western Banded Gecko (Coleonyx variegatus) is very common in the Sonoran desert, and can easily be found under rocks during the day, where they lie in wait for dark. At night, they’re easily encountered as well. The pattern can be pretty variable as well. I’ve seen them with such diminished patterning that they look almost a solid tan/pink color, as well as banded, spotted, and any combination of both.
The tiny bead-like scales and flexible skin give them an incredibly soft texture. They’re also capable of vocalizing, which is unique in lizards to the geckos. When scared, they will sometimes chirp.
They are easily sexed, as males have large, visible bulges to either side of the tail base. This one is a female.
