One of the easies herps to find in AZ are geckos. They have mediterranean house geckos, and banded geckos (coleonyx). YOu will fing the mediterranean geckos on walls and sometimes on the ground, and you will almost always find the banded geckos on the ground. don't worry about a bite because they do not hurt much, (or at all). Good luck. And another thing is that coleony and mediterranean geckos are very easy to keep in captivity. Just feed them crickets and provide an undertank heater on one side of the enclosure. Also, if you collect them, DO NOT keep 2 males of coleonyx aniwhere near eachother, they will fight and maybe even kill. You can identify the males by the spiky protrusions on each side of the base of the tail. I do not find this problem with the mediterraneans though.
