Cholla Garden, Joshua Tree National Park, Riverside County, CaliforniaJune 21, 1998
Western Side-blotched Lizard (Uta stansburiana elegans)
Side-blotched lizards are the most common lizards in the deserts of southern California.
Lost Palms Oasis Trail, Joshua Tree National Park, Riverside County, CaliforniaJune 21, 1998
Western Side-blotched Lizard (Uta stansburiana elegans)
This side-blotched lizard was probably drawing a little more attention to itself than it intended.
Pine Ridge Trail, Ventana Wilderness, Monterey County, CaliforniaAugust 23, 1998
Western Side-blotched Lizard (Uta stansburiana elegans)
When I first posted this photo, I bemoaned my lack of certainty about the subspecies of Uta stansburiana, which caused helpful reader Jackson Shedd to point out that Smith and Brodie's guide lists 6 subspecies and includes range maps. These subspecies have been revised since then, and I'm currently using the subspecies as described in the most excellent Lizards of the American Southwest. And Jackson Shedd is still a helpful reader and friend.
Red Rock Canyon State Park, Kern County, CaliforniaMay 29, 1999
Western Side-blotched Lizard (Uta stansburiana elegans)
Red Rock Canyon is yet another thriving nest of side-blotched lizards. This one is female (the males, like the one above from Cholla Garden, are more speckly).
Red Rock Canyon State Park, Kern County, CaliforniaApril 22, 2000
Western Side-blotched Lizard (Uta stansburiana elegans)
Here is a vividly colored male at the height of its breeding-season colors. The scan doesn't do it justice, but this was one colorful lizard.
Butterbredt Spring, Kern County, CaliforniaApril 22, 2000
Western Side-blotched Lizard (Uta stansburiana elegans)
This is how to make baby side-blotched lizards. The male has a firm bite on the female's neck. She looks like she just wants to get it over with.
Alabama Hills, Inyo County, CaliforniaSeptember 15, 2003
Western Side-blotched Lizard (Uta stansburiana elegans)
This male was posing nicely among the beautiful and bizarre rock formations at Alabama Hills. Perhaps I should start a collection of lizards perched in rock crevices, which would include this side-blotched lizard from California, a fence lizard from Utah, and a gecko from Australia.
Death Valley National Park, Inyo County, CaliforniaApril 1, 2005
Western Side-blotched Lizard (Uta stansburiana elegans)
Having plenty of pictures of side-blotched lizards, I took this photo mainly to show off the purple flowers in the background. 2005 was a banner year for desert wildflowers in Death Valley and elsewhere in the southwestern U.S., and my wife's favorite color is purple.
Borrego Palm Canyon, Anza-Borrego Desert State Park, San Diego County, CaliforniaJuly 3, 2006
Western Side-blotched Lizard (Uta stansburiana elegans)
It was so hot when I was in Anza-Borrego that most of the lizards went into hiding for the day after about 9:30 AM. As usual in the desert, the side-blotched lizards were the first ones out in the morning, and as usual in the desert, they were out in force. This was one of the first ones I saw, at about 7:30 AM. I stopped taking pictures of side-blotched lizards as soon as the less widespread and less common lizards started coming out, such as granite spiny lizards and banded rock lizards. I did keep counting them though, and I ended up seeing 77 side-blotched lizards between 7:30 and 9:45.
Alabama Hills, Inyo County, CaliforniaSeptember 10, 2006
Western Side-blotched Lizard (Uta stansburiana elegans)
Here's an adult female Side-Blotched Lizard looking warily at me from its boulder perch. There weren't too many lizards out on that morning, but you can usually count on there being a few side-blotched lizards anywhere in the California desert.
Red Rock Canyon State Park, Kern County, CaliforniaApril 17, 2009
Western Side-blotched Lizard (Uta stansburiana elegans)
This was probably the most obviously gravid female side-blotched lizard that I've ever seen. (For those unfamiliar with lizard lingo, "gravid" means "pregnant, but with eggs rather than babies".)
Borrego Palm Canyon, Anza-Borrego Desert State Park, San Diego County, CaliforniaApril 24, 2009

On a warm spring morning, it seemed like every boulder had a male side-blotched lizard at the highest point, trying to impress the gals. Some of them seemed to have succeeded in this endeavor.
Pacific Crest Trail, Ranchita, San Diego County, CaliforniaApril 25, 2009
Western Side-blotched Lizard (Uta stansburiana elegans)
We had hiked for a half mile or so on a cool morning (low sixties) with no sign of reptilian activity. I was beginning to think that it was to be a herp-free morning when I spotted this pretty female on a pink rock. I later saw a few more side-blotched lizards and then a couple of very dark fence lizards.
Carrizo Plain National Monument, San Luis Obispo County, CaliforniaJune 17, 2012
Western Side-blotched Lizard (Uta stansburiana elegans)
This is the second-most obviously gravid side-blotched lizard I've photographed.
Between Mike's Sky Rancho and Rancho el Coyote, Baja California, MexicoMay 15, 2013
Western Side-blotched Lizard (Uta stansburiana elegans)
The islands off of Baja California are filled with a number of side-blotched lizard variants, many of which are considered separate species. But the peninsula itself has the same old Uta stansburiana that populates most of the U.S. southwest. This is not the most pristine specimen, with its underleg mites and tail stump.
Pima County, ArizonaAugust 20, 2013
Western Side-blotched Lizard (Uta stansburiana elegans)
This is probably my favorite photo from this nine-day trip to southern Arizona, although this lizard is the most common herp in the area. He looks so proud, overseeing his dominion, while keeping a wary eye out for photographers and collared lizards.
Alamo Canyon, Organ Pipe National Monument, Pima County, ArizonaAugust 3, 2014
Saw a few of these in Alamo Canyon, but didn't get any photos worth displaying.
Pilot Knob, Imperial County, CaliforniaMay 20, 2015
Western Side-blotched Lizard (Uta stansburiana elegans)
Pilot Knob sounded like a good place to hike from some description I had read on the web, but turned out to be highly degraded from (legal) off-road vehicle use. Maybe there were some more interesting animals lurking about somewhere, but all I saw in a quick visit were a few side-blotched lizards.
SARA Mountain Park, Lake Havasu City, Mohave County, ArizonaApril 14, 2016
Western Side-blotched Lizard (Uta stansburiana elegans)
My first photographed side-blotched lizard from Mohave County, Arizona. Something to be proud of.
Bahía de Kino, Sonora, MexicoAugust 18, 2017
Western Side-blotched Lizard (Uta stansburiana elegans)
Definitely the least exciting lizard in Mexico. But any lizard is better than no lizard at all.
Carrizo Plain National Monument, San Luis Obispo County, CaliforniaMay 23, 2021
Western Side-blotched Lizard (Uta stansburiana elegans) Western Side-blotched Lizard (Uta stansburiana elegans)
Though it was very hot and extremely dry, the weather did not deter side-blotched lizards from proudly perching on boulders. The first one is an adult male; the second one is a probably-gravid adult female.
Borrego Palm Canyon, Anza-Borrego Desert State Park, San Diego County, CaliforniaMay 26, 2021
Western Side-blotched Lizard (Uta stansburiana elegans)
Yes, they are incredibly common. But they are still fine-looking lizards, and one can always practice one's photography.
Uta stansburiana nevadensis Nevada Side-blotched Lizard
Fort Rock State Natural Area, Lake County, OregonSeptember 3, 2013
Nevada Side-blotched Lizard (Uta stansburiana nevadensis)
Fort Rock is a castle-shaped outcrop of rock in the middle of an otherwise flat sagebrush plain. I wanted to visit specifically in the hopes of finding Pygmy Short-horned Lizards, but was unsuccessful. I had to take a new-to-me subspecies of side-blotched lizard as a consolation prize.
Uta stansburiana stansburiana Northern Side-blotched Lizard
Kolob Canyons Viewpoint Trail, Zion National Park, Washington County, UtahAugust 30, 1998
Northern Side-blotched Lizard (Uta stansburiana stansburiana)
This genus was named after Utah, where these colorful little lizards were first identified in 1852.

I am guessing that the Zion subspecies is U. s. stansburiana, but it might be U. s. uniformis. Please send me email if you know more.

Uta stansburiana stejnegeri Eastern Side-blotched Lizard
Bitter Lake National Wildlife Refuge, Chaves County, New MexicoMay 23, 2008
Eastern Side-blotched Lizard (Uta stansburiana stejnegeri)
There wasn't much herp activity on a hot windy afternoon at Bitter Lake National Wildlife Refuge, but at least I finally got a photo of a local side-blotched lizard after several had escaped my camera earlier.
Bottomless Lakes State Park, Chaves County, New MexicoMay 24, 2008
Eastern Side-blotched Lizard (Uta stansburiana stejnegeri)
The next day I finally got a photo of one of the local male side-blotched lizards.
Big Bend National Park, Brewster County, TexasApril 21, 2010
Eastern Side-blotched Lizard (Uta stansburiana stejnegeri)
I saw surprisingly few side-blotched lizards in Big Bend National Park, compared to most U.S. deserts that I've visited. This chubby (probably gravid) female was the only one I saw one afternoon. Usually when I see one, I end up seeing dozens.
Palo Duro Canyon State Park, Randall County, TexasApril 25, 2011
Eastern Side-blotched Lizard (Uta stansburiana stejnegeri)
I only saw a couple of side-blotched lizards on a late afternoon hike in Palo Duro Canyon State Park also, but that was still two more lizards than I saw of any other species on a chilly afternoon.
Uta stansburiana uniformis Plateau Side-blotched Lizard
Dead Horse Point State Park, Wayne County, UtahJune 19, 2001
Plateau Side-blotched Lizard (Uta stansburiana uniformis)
The side-blotched lizards here had evolved a nice reddish color for camouflage against the beautiful red rock formations of this park, which is near the similar but more famous Canyonlands National Park.
Colorado National Monument, Mesa County, ColoradoApril 29, 2006
Plateau Side-blotched Lizard (Uta stansburiana uniformis) Plateau Side-blotched Lizard (Uta stansburiana uniformis)
Plateau side-blotched lizards tend to be less colorful than other subspecies (hence the uniformis), and these two were no exception. They do blend in nicely on the red rock formations though. The first photo is an adult male, and the second photo is an adult female.
Fisher Towers, Grand County, UtahMay 28, 2009
Plateau Side-blotched Lizard (Uta stansburiana uniformis) Plateau Side-blotched Lizard (Uta stansburiana uniformis)
Here's another pair showing off how remarkably drab this subspecies is.
Moab, Grand County, UtahApril 18, 2016
Plateau Side-blotched Lizard (Uta stansburiana uniformis)
More drabness, but I like how well they match the reddish rocks on which they hang out.
Moab, Grand County, UtahApril 21, 2016
Plateau Side-blotched Lizard (Uta stansburiana uniformis)
This one's going for a sort of two-toned effect. Still not un-drab.
Arches National Park, Grand County, UtahApril 22, 2016
Plateau Side-blotched Lizard (Uta stansburiana uniformis)
I suppose I could have been taking photos of the spectacular geology at Arches National Park instead.
Goblin Valley State Park, Emery County, UtahJuly 19, 2017
Plateau Side-blotched Lizard (Uta stansburiana uniformis)
I saw a handful — but only a handful — of side-blotched lizards in the nearly vegetation-free interior of Goblin Valley State Park. It seems like the terrain wouldn't support much lizard density since there were so few plants and thus so few insects for the lizards to snack on. I pondered how these little guys could find mates, but obviously they've been doing so for a long time.
Devil's Garden, Garfield County, UtahJuly 26, 2017
Plateau Side-blotched Lizard (Uta stansburiana uniformis)
While the rest of my group was carefully posing their ten-plus collective dogs, I snuck away to look for scenically arranged lizards.
Goblin Valley State Park, Emery County, UtahMay 22, 2022
Plateau Side-blotched Lizard (Uta stansburiana uniformis) Plateau Side-blotched Lizard (Uta stansburiana uniformis)
The light spots on a field of uniform reddish sand color was a Side-blotched Lizard style that I hadn't previously encountered.
Mill Creek North Fork Trail, Moab, Grand County, UtahMay 23, 2022
Plateau Side-blotched Lizard (Uta stansburiana uniformis)
Pretty darn good at matching the background color.
