The Oblivious Birder.
Jeff created this photo for use in a recent keynote address given at the Spacecoast Bird & Wildlife Fest. Clearly this was tongue in cheek as the birder is completely unaware of the oncoming traffic. However, when he gave the example all admitted that they had seen someone on past field trips where folks had to be asked to get out of the road to allow traffic to pass! He also used this photo as a segue into his look at "birder fashion"!

I have been digging through my image archives in my gmail account and found some real treasures that my readers sent to me. Unfortunately, I overlooked quite a few images that were sent when I was in the hospital and had poor computer access. So let me fix this oversight during the next few weeks;

This looks like Mt. Rainier to me, but maybe one of you has a better idea of this mountain's identity (and also, what is the name of the lake in the forground?)

Lutrochus arizonicus - Travertine Beetle
Arizona, USA
Here's an odd sort of beetle of whose existence I was entirely ignorant until a few showed up in our lab. My primary research these days is with the Beetle Tree of Life group, and the travertine beetle is just one of many Coleopteran wonders I've been introduced to over the past couple of years. This one is especially cute.
These little guys are aquatic, clinging to rocks in fast-moving streams. They're rather picky animals and not just any rocks will do. They need a particular kind of limestone called Travertine. The long tarsal…

 Formica accreta, Northern California
I wish I could say I knew what these ants were doing. Hiding from the photographer, perhaps? Formica of the fusca species group are notoriously shy insects, but not all of these ones seemed to be equally spooked.

In 1934, a diminutive book by an unknown author seeded the largest conservation movement in history. The book, Roger Tory Peterson's A Field Guide to the Birds, pioneered the modern field guide format with crisp illustrations of diagnostic characters, all in a pocket-sized read. The Guide sold out in a week, but the book's effects are ongoing.
To understand the magnitude of Peterson's impact, consider how naturalists traditionally identified birds. They'd take a shotgun into the field, and if they saw something of interest they'd kill it. Birding was necessarily limited to the landed-…

Dineutes sublineatus - whirligig beetle
Arizona, USA
Whirligigs are masters of the thin interface between air and water, predating on animals caught in the surface tension.  In the field it can be hard to appreciate the finely sculptured details of their bodies, the erratic movements that give them their name also make them hard to observe and to catch.

Arizona is thankfully immune to the bizarre tendency of states to pick imported species, as if the tens of thousands of naturally-occurring species weren't quite good enough. Ours is the two-tailed swallowtail (photo by Jeffrey Glassberg):
awild | February 3, 2008I have thousands of absolutely awful photographs on my hard drive. I normally delete the screw-ups on camera as soon as they happen, but enough seep through that even after the initial cut they outnumber the good photos by at least 3 to 1. Here are a few of my favorite worst shots.
Thinking that nothing would be cooler than an action shot of a fruit fly in mid-air, I spent an entire evening trying to photograph flies hovering over a rotting banana. This shot is the closest I came to getting anything in focus.
That's a nice finger in the background. It's mine, you know.
Imagine how…
awild | February 1, 2008My early bug photos, the ones I don't show anyone anymore, are poorly-exposed affairs that now sit hidden in my files. If I had to put my finger on the single biggest problem with these embarrassing first attempts, I'd say that I lacked an eye for composition. I was so intent on getting the bug in focus somewhere in the LCD that I paid no attention to what else ended up sharing the frame. Turns out, all sorts of extraneous crud. Bits of grass. Dust. My finger. Many of these images are so crowded that it just isn't clear what I ought to be looking at.
Understanding why busy compositions…

Onthophagus gazella
Gazelle Scarab, Arizona
At my current rate of once-a-week Beetle Blogging, I'll need 10,000 years to cover every living species.
Wish me luck.

We often think of ants as paragons of hard work, but a surprising number of species get by through mooching off the labor of others. Trachymyrmex fungus growers, the larger spiny ants pictured above, do things the old-fashioned way. They dig their own nests, send workers out to gather food, and meticulously cultivate the fungus garden that serves as the primary food source for the colony.
Then, along comes the slim, sneaky Megalomyrmex symmetochus. These little parasites hollow out a cozy little nest within the Trachymyrmex garden and spend their time leisurely consuming the brood of…

Here's a story about a parasitic nematode that turns black ants into ripe red berries. What's this about?
The parasite needs to get its eggs from an infected ant to healthy ants. Apparently it hasn't been successful the old-fashioned way, just broadcasting its eggs about the environment. Instead, these little worms have figured out a far more effective egg delivery vehicle: birds.
Ants of the genus Cephalotes often feed from bird droppings (for instance, see here). If a parasitic egg can get itself into a bird's digestive system, it'll wind up in a juicy fecal pellet where it may be…
