Western Side-blotched Lizard

Uta stansburiana elegans

Description:

Orange and brown lizard with pattern down back. There's a dark blotch behind each front leg which gives it its name. This one has an orange throat. "A small (1.5 - 2.5 inches long from snout to vent (3.8 - 6.3 cm)) brownish gray lizard with small smooth granular scales on the back, larger scales on the head and limbs, a gular fold, a long thin tail and a dark blue-black mark on the sides of the chest behind the front limbs, which gives this lizard its name.. This mark is sometimes faint or absent. Color is brown, gray, yellowish, or black, with dark blotches, spots, and sometimes stripes. Often there is a double row of dark spots or wedges on the back, edged with white on the rear. The underside is whitish to gray and mostly unmarked. The throat is mottled with dark and light. Females are blotched on top with brown and white, often with stripes, and have a less well-defined blotch on the sides. They have no blue speckling, and no color on the throat." - California Herps

Habitat:

Trail head at Daley Ranch. "In California, this subspecies is found throughout the southern deserts and coastal region, north through the central valley and coast ranges to just south of the Bay Area, extending northward to the Sacramento River, and on Santa Cruz, Anacapa, San Clemente, and Catalina Ialands. Its range outside California continues into western Arizona, extreme southwestern Utah, and southern Nevada. The species as a whole ranges north into central Washington, east into west Texas, and south into Mexico, including all of Baja California. Prefers open rocky areas with scattered vegetation, including the edges of sandy washes. Utilizes a wide variety of habitats, including hardpan, sandy, rocky, and loamy areas grown with chaparral, scattered trees, grass, shrubs, and cactus. From below sea level to around 9,000 ft. (2,700 m)" - California Herps

Notes:

"Three subspecies of Uta stansburiana are sometimes shown occuring in California, including U. s. stansburiana - Northern Side-blotched Lizard, which is shown to range east of the Sierra Nevada Mountains in Inyo and Mono counties. " - California Herps

That's awesome! I'm happy to say that there are a ton of them around here.

In the case of a Western Fence Lizard,Studies have shown that Lyme disease is lower in areas where the lizards occur. When ticks carrying Lyme disease feed on these lizards' blood (which they commonly do, especially around their ears), a protein in their blood kills the bacterium that causes Lyme disease. The ticks' blood is therefore cleansed and no longer carries Lyme disease

Eek. I retract my comment :) Males have the thicker base of the tail and females don't have color on the throat! Gosh these lizards are variable. Great job Emma!

How funny, I was just cropping the first image to show detail to determine the gender! This seems to be a female although the gray undertones do appear blue. The males have blue spots. Here's a female: http://www.californiaherps.com/lizards/i...
Here's a male: http://www.californiaherps.com/lizards/i...

Cindy,if you look carefully do you see a tinge of blue in the pattern?
I can.
In the Western Fence lizard,blue is considered as a sign for a male.
