Tucson Banded Gecko

Tucson Banded Gecko (Coleonyx variegatus bogerti)
These delicate little pastel-colored lizards seem too fragile to survive in the extreme heat and dryness of the southwestern U.S. deserts, but they get along just fine, thank you, primarily by coming out only at night. I've heard that they're often mistaken for baby Gila monsters due to their pinkish hues and banded pattern, but this mistake is presumably made only by people who've never seen a Gila monster in person. Banded geckos are tiny, fragile-looking, smooth, and fast, whereas Gila monsters are huge, bulky, bumpy, and slow. This one and one other were found on a night where our main goal was to find a Gila monster, but alas, it was not to be.

Tucson Banded Gecko (Coleonyx variegatus bogerti)
Driving back home after an evening of radio-tracking Gila Monsters and rattlesnakes, my friend Roger Repp and I drove through a sandy area in which Roger had frequently seen sidewinders. We had no luck with the sidewinders that evening, but found a couple pretty little geckos as a consolation prize.

I finally found a banded gecko during the day (under a rock) so I could get some decent pictures. Over the course of three weeks, I ended up finding nine of them under rocks. They're pretty twitchy and are not so fond of being uncovered for long, so it takes some patience to get them to pose.

Banded geckos are most often seen at night on roadways. They look like leaves blowing across the road.

Desert Banded Gecko (Coleonyx variegatus variegatus)
I was driving on the road at night looking for nocturnal snakes and lizards when I caught the white reflection of this little gecko in the road. For a moment I was very excited, because I was in an area of Anza-Borrego known to contain the elusive Barefoot Gecko (Coleonyx switaki). But after pulling my car over, grabbing my camera and flashlight, and racing back to where the gecko was, all that awaited me was a fairly common Desert Banded Gecko. Still, they are beautiful little lizards.

Desert Banded Gecko (Coleonyx variegatus variegatus)
Here is a much larger and more robust banded gecko from the same general area as the previous one. I saw quite a few of these pale lizards on the roads at night, From a distance, they look like a small stick or leaf on the road, but they generally have their heads lifted (and sometimes also their tails), so they do have a fairly distinctive shape that is not too hard to recognize with some practice.

Desert Banded Gecko (Coleonyx variegatus variegatus)
This one from a few days later is also a robust adult. Its more purely banded appearance makes it look superficially like the San Diego Banded Gecko (Coleonyx variegatus abbotti). However, that subspecies is typically found west of the Peninsular Ranges and this one was crawling across highway S2 to the east of said mountains. Also, the San Diego Banded Gecko has a distinctive light stripe from the back of the eyes to the collar that this one lacks. So this just shows part of the range of appearance of this species even within a relatively small area.

Desert Banded Gecko (Coleonyx variegatus variegatus)
Banded geckos are a sort of consolation prize for herpers out looking for nocturnal snakes or rarer gecko species. You can usually find a few on any decent herping night, even when the snakes and other lizards are playing hard to get.

Here's another one on the next night, with a much more solid-banded pattern.
