Taken in Tucson, Arizona using a Canon Powershot SX10IS. Though I wish the light was different, it was nice of him to stop for a brief moment so I could get off a few shots.
A medium sized, flat and broad lizard. Long horn-like scales protrude from the back of the head. Various shades of brown overall, with highlights of orange or salmon along the lower edges of the body. Coloration often matches the soil on which they are found. Almost always has a pair of dark blotches on the neck. On the back are scales and irregular dark blotches. There is but a single fringe of enlarged, pointed scales on each side.
Found in Sonoran and Mohave desert scrub, as well as Great Basin Desert scrub. Usually encountered in flat, open areas with sparse vegetation. Most likely to run than most horned lizards, although it often stops after a short sprint. Eats ants, other insects and some plants. Lays one or two clutches of up to 16 eggs from May to August.
► Dorsal strip is faint or absent
► Single fringe of enlarged pointed scales along side body.
