awild | June 22, 2008A 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…

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…

Olla v-nigrum - Ashy Grey Ladybird Beetle
Arizona
Here it is: the very first ladybird beetle featured on the Friday Beetle Blog. Instead of a boring ol' red and black one, I've chosen a stylish and tasteful beetle colored in grayscale: the Ashy Gray Ladybird. These have been arriving in some numbers at my blacklight this week. Like most members of the family Coccinelidae, Olla beetles are predators.

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…

Arizona
The Opuntia prickly-pear cacti have been flowering the past few weeks. Every time I poke at a blossom I find several chunky Carpophilus beetles.

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…

Rose Aphids - Macrosiphum rosae
Tucson, Arizona
It's fair to say that without the encouragement of my mother, who allowed all manner of newts, snakes, caterpillars, tadpoles and ants into the house, I would not have gone on to become a biologist.
Thanks Mom, and happy mother's day!

Amphizoa insolens - trout stream beetle
California
Amphizoa are among the more enigmatic insects I've photographed. These dime-sized beetles are found only in the mountains of China and western North America, a disjunct distribution paralleled by a number of interesting taxa, including the giant redwoods. All six species are predaceous and aquatic, living in debris and under stones in fast-running creeks. Because adults have a morphology suggestive of the terrestrial ground beetles, some researchers have proposed that Amphizoa represents an evolutionary transition between terrestrial and…

Distremocephalus - Phengodidae
Arizona
The beetle family Phengodidae is odd any way you look at it. The adult female (not pictured) is larviform, which means she never loses her grub-like appearance as she grows into sexual maturity. She has no wings and no long antennae. But she does bioluminesce, and that gives the family their common name: Glow-worms.
In stark contrast to their grubby counterparts, male phengodids are delicate creatures, adapted for dispersal and mating. The male pictured above flew to a blacklight behind my house. I don't see phengodids all that often at the light,…

Myrmecos.net is 5 years old. It has grown from a few dozen photographs to about 4,000, and in recent years 1,500 people visit the site every day. In spite of the site's high profile, myrmecos has not changed in any fundamental way since it first went online in 2003 (archived versions are accessible here). The pages are simple 1990's technology, hand-written in html. There are no underlying databases, just scores of flat files stored in folders. If you do any web design you can imagine what a pain in the behind it is to manage a static site with thousands of individual html files.

Eusattus dilatatus - dune darkling beetle (Tenebrionidae)
California, USA
Sand dunes are an unusual habitat, and the creatures found on them are equally odd. One of the more charismatic dune endemics is Eusattus dilatatus, a large darkling beetle found in southern California. This scavenging insect has long legs for digging and a waxy cuticle to prevent dessication.
Eusattus is not the easiest photographic subject. It seemed uncomfortable out in the open and would burrow as soon as I placed it on the sand. The series below spans 30 seconds.

Proceratium californicum
San Mateo Co., California
From Antweb:
This rarely collected ant is known from valley oak (Quercus lobata) riparian woodland in the Central Valley and from adjacent foothill localities (oak woodland; chaparral; grassland). It is presumed to be a specialist, subterranean predator on spider eggs. Alates have been collected in April and May.

Velvet ants- which aren't really ants at all- are wingless wasps that parasitize ground-nesting bees. They are attractive insects, bearing bright colors and cute frizzy hair. But in case you are ever tempted to pick up one of those cuddly-looking little guys, let the photo above serve as a reminder about what lies at the tail end: an unusually long, flexible stinger. As you can see, the wasp is capable of swinging it back over her shoulder, with perfect aim, to zing the forceps. The venom is potent, and in some parts of the U.S. these insects are called "Cow-Killers". As is always the…

Araeoschizus sp. Ant Beetle (Tenebrionidae)
California
Araeoschizus is a small genus of darkling beetle that both resembles ants and lives close to ant nests. It occurs in the arid western regions of North America. Not much is known about the nature of the association of these beetles with the ants, but they may subsist on the refuse of harvester ant colonies.
