The original installment of Macro Thursday was evidently quite popular with my readers, thank you. So, I have decided to make it a semi-regular feature within the realm of the Logical Lizard.

The idea here is to use the ultra-fab macro lens on my favorite digital camera to capture hidden details of the natural world. All of these photos were taken in a single day during a lengthy hike through the Rincon Mountains, outside of Tucson. Amazing what you can see if you take the time to stop and look.

Why did the tarantula cross the road? My hiking companion claimed it was because she wanted me to pick her up and stroke her belly—apparently they like that. I didn't see my friend rushing over to do any such thing, so I was happy to just take the photo and skip the belly rub.

During the past few weeks, despite the appalling heat, I have been enjoying a lot of adventuring and rockhounding in the Sonoran Desert. When I am out in the field I always carry a little pocket Nikon digital camera with me. I need a camera or three, primarily, to document our expedition work, but I also like to pause and take pictures of the life around us. I have always been fascinated by the details of the natural world, particularly patterns and shapes. Stopping to appreciate them for a moment, here and there, can be a welcome break from sometimes arduous field work.

A good macro (close-up) lens allows an observant and patient photographer to examine the minutiae of the plants and animals that live with us here in the Sonoran Desert—a unique habitat teeming with natural wonders, some of them not found anywhere else in the world.

In the old days, the dedicated photographer had to haul a bulky macro lens around in the camera bag and mount it on an SLR for those close-up shots. Digital cameras, with their built-in macros, have made those brief journeys to inner space so very much easier, but no less fascinating.

Here are some details from this week’s adventures.

A beautiful cluster of Coryphantha vivipara, the "Bisbee Beehive." This elegant plant is rarely seen around greater Tucson.

Industrious red ants working on their cave. Don't let these guys bite, it really hurts.

Ferocactus wislizenii is a survivor. Three new heads grew from the body of this injured plant.
