If you photographed this lizard anywhere but in the San Diego County area, I am fairly certain that your photo is of a Sonoran Spotted Whiptail (Cnemidophorus sonorae). If it was photographed in the San Diego County area, there is a very slight possibility it is the rare Belding's Orange-throated Whiptail (Aspidoscelis hyperythra beldingi) - though I doubt it.

I'm thinking maybe a Desert Grassland Whiptail (Cnemidophorus uniparens), because of the lack of spots on the body.
Shot just beyond the trees to the right of the photo at Cathedral Rocks, Sedona, Az.
The range maps show the grassland whiptail overlapping both the plateau and spotted whiptails, where the spotted are located more to the south and the plateau separate and further north. The tail (not shown for the sake of composition) is olive rather than the bluish color described for the plateau.
Lizards is cool.

Ah, I didn't know you were that far south! Likely the Desert Grassland Whiptail as you so guess, though the Sonoran Spotted Whiptail looks the exact same with only the added feature of some very faint dots between the stripes.

Yes, I took the administrative tour of the depot and was throughly impressed in the work the contractors did. I even played tourist and videoed a train or two. Back for another week starting tomorrow.

The preserve is thick with history. See it all.

Here's another interesting shot I found recently....
I'm posting it here because
A) it's a spider
and
B) I shot it using a technique I'd read about but never tried before, and it worked! sort of.
This is a way of faking it when you don't have a macro lens with you. I took my standard zoom (which was probably at around 70mm?) and reversed it - holding the front element tightly against the camera body, the rear element facing the subject. It works! BE CAREFUL - you are exposing the (expensive) rear element to dust and scratches, as well as the inner workings of the body. Not a good technique for rainy days, dusty days, or windy days.
I did some experimenting today:
First, I shot as close as I could with my 17-40mm:
Then, I shot as close as I could get with my 28-200 zoom, set at 200mm:
The camera was about 1 meter from the subject. This got me a little closer.
Then, I set it at 28mm, reversed it, and shot through it in reverse. The camera was now about an inch or less from the subject:
Focussing is a pain in the ass - you do it by moving your body in/out until the subject crosses the plane of focus; you have to hold very steady. But in a pinch, it works, and it's much cheaper (and lighter) than closeup rings, reverse-mount rings, bellows, etc. etc. |

Wow that's an interesting technique. It's incredable how close you can get using that technique. The picture of the spider looks like a cell phone camera photo.

The boards have been DEAD this weekend, so I thought I post some more bug pictures before I take off for another week in Mojave Preserve....
This dragonfly took a fond liking to my rent-a-lamp after he rudely invaded without knocking. And trust me, he is plenty big enough to knock.
And a real close up of his body and legs. What is he?

Not sure what this fellow (?) is, but as I have dozens that I need to ID. so it seemed like a good time for me to do some looking. Seems that there is not much on the web to ID dragonflies, nothing like I located for butterflies. Perhaps someone will be able to ID it or come up with a good website to help you ID it.
With the site being down for several days and with GBR leaving, seems that something has been lost. |
