The leaf litter around the San Pedro river was busy with the scuttling and scritching of these constantly-moving lizards. This is another of the all-female virgin-birth-giving whiptail species, as you might guess from its scientific name.

This species was placed in the genus Cnemidophorus until recently, so most reference books still use that name.

On a return trip to the same area, I saw another large batch of these lizards skittering about. Every once in a long while one would pause to bask for long enough that I could get a photo.

We spotted another momentarily-basking whiptail the next day.
