awild | July 21, 2008Oecophylla weaver ants are exceptionally cooperative subjects for photography, allowing for plenty of experimentation with lighting while the ants preen and pose. While developing the photographs from South Africa I discovered that strong backlighting allows a crystal-clear view of the tracheal system:
Oecophylla longinoda, St. Lucia, KZN, South Africa
The tracheae are visible as dark canals running through the body. These connect to the outside air in a series of circular spiracles and are essentially the lungs of the insect, channeling oxygen to the respiring cells and carrying away…

This video was sent to me by a Brazilian blog pal who "reads my blog every day"! It is a collection of beautiful nature images by award-winning photographer Andre Seale, who happens to be her husband. The soothing music was composed and performed on GarageBand. [3:13]
Be sure to leave some feedback for her to read.

Chrysina (=Plusiotis) gloriosa - The Glorious Beetle
Huachuca Mountains, Arizona
Few of Arizona's beetles are as spectacular as the jewel scarabs in the genus Chrysina. They are most readily collected by blacklight (as in Kojun's handful o' beetles) in juniper forests in the weeks following the arrival of the monsoon.

Yesterday's unexpectedly intense monsoon storms brought several inches of rain and flash floods to Tucson. Many of our desert ants cue their mating flights with the onset of the summer rains, and this morning the Forelius were flying, congregating in dense swarms that twirled and twisted above the desert floor.
Males emerge from the nest, ready to go:

awild | June 23, 2008Via GTDA comes this mesmerizing time lapse video demonstrating the efficiency of ant recruitment:
awild | June 22, 2008 A century ago, William Morton Wheeler inked this iconic illustration of the striking polymorphism displayed among members of an ant colony. You may have seen it; Andrew Bourke and Nigel Franks used it as the cover for their 1995 text Social Evolution in Ants.
I always assumed Wheeler's figure depicted some exotic tropical marauder ant, a voracious jungle species with massive soldiers for slicing up hapless prey. I don't read captions carefully enough, I guess, because I learned recently that this charismatic creature is actually a local harvester ant, Pheidole tepicana. Not only that, but…

After I returned from Manhattan, Kansas, I thought of it as a wonderful, magical place where I would always be able to return, to see birds and photograph lots of native wildlife, to find a warm and safe place with my good friends, Dave and Elizabeth. (I am sure all of you know Dave quite well, since his gorgeous photographs are often featured as the "Image of the Day" on this site.) But while I was preoccupied with my imaginings, I was…

Derobrachus hovorei - Palo Verde Borer
Cerambycidae
Tucson, Arizona
Every June, hundreds of thousands of giant beetles emerge from beneath the Tucsonian soil. The enormous size of these beetles- up to several inches long- makes them among the most memorable of Tucson's insects. They cruise about clumsily in the evenings, flying at eye level as they disperse and look for mates.
Palo Verde beetles spend most of their lives as subterranean grubs feeding on the roots of Palo Verde trees. Adults emerge in early summer, usually ahead of the monsoon, and by August they are gone.
It is still a…

Centruroides sculpturatus - Arizona Bark Scorpion
I have a hard time getting worked up over stuff that happened 25 years ago. But here's something that still angers me every time I think of it.
One of those educational safety movies we were shown back in grade school- you know, the "Stop-Drop-and-Roll" variety- presented the dangers of the Bark Scorpion. The film featured dark tones and a dramatic reenactment of a deadly encounter, complete with screams and fainting.
This was shown in Rochester, New York, mind you. We don't have scorpions anywhere near Rochester. The climate is is far…

This basic photo of a harvester ant carrying a seed took an hour and a half to capture. 150 exposures. The problem wasn't that the ants weren't behaving, but that it took nearly an hour of experimentation to get the simplicity of composition I had envisioned when I set out on the project.
Few of my better photos are one-off shots.
Most exist in my head in some form or another before I attempt to shoot them, and once I've started a session they take a bit of experimentation before finding the right conditions. Yesterday I headed up towards Mt. Lemmon where I knew of several nests of the…

Spring is swarm season for honeybees, and the feral population in Tucson is booming. We've got not one but two new colonies nesting in dead trees in our yard. I didn't do anything to attract them, they just moved in on their own.
My feelings about honey bees are mixed.
On one hand, I have many fond memories of working as a beekeeper back when I was in Peace Corps. There's something exhilarating about opening a hive, feeling the vibration of thousands of little wings, the scent of honey and wax thick in the air. Bees are charismatic creatures, and although I worked with them pretty…

Opamyrma hungvuong Yamane et al 2008
Vietnam
It isn't every day we get a whole new genus. In this week's Zootaxa, Seiki Yamane, Tuan Vet Bui, and Katsuyuki Eguchi report the discovery of Opamyrma, an amblyoponine ant from central Vietnam. The full article is behind Zootaxa's subscription barrier, but detailed specimen photos are already up at Antweb.
The ant subfamily Amblyoponinae is an ancient group. They diverged from the other ant lineages prior to the evolution of trophallaxis food-sharing behavior, and have instead adopted an odd and seemingly brutal way of passing food around the…

Pheidole pegasus Sarnat 2008
Fiji
Eli Sarnat, the reigning expert on the Ants of Fiji, has just published a lovely taxonomic revision of a group of Pheidole that occur on the islands. Pheidole are found in warmer regions worldwide, but Fiji has seen a remarkable radiation of species that share a bizarre set of spines on the mesosoma. Eli sorted through hundreds of these things to determine that the group contains seven species, five of which had not previously been described. Pheidole pegasus is largest and among the most distinct of the group. It was collected only once, from the…

The visit of Australian friends a couple weeks ago provided an excuse to go photograph Arizona's most famous landmark. Appearances aside, the Grand Canyon is not an easy subject. Most shots appear flat in comparison to real-time views, failing to capture the canyon's immense depths or the enormity of the open space. This is true of much landscape photography, and I've come to respect the people who are good at it.
Our trip had the additional challenge of a perfectly clear day. Blue sky sounds nice in the abstract, but a lack of clouds means a boring sky and hopelessly bottom-heavy…
