Army ants!

Here's Labidus, another under-appreciated army ant. These workers are
guarding a foraging trail.

Ant vs. termite

It seems like the winner of this setup is generally 'ant,' but here's
a cool shot of a termite soldier getting one in for the woodeating
cockroaches, squirting some sticky goo onto the ant. The ant, as best
I can tell, is <i>Acanthostichus</i>, a nifty subterranean army ant in
the subfamily Cerapachynae.

This one didn't end well for Team Termite -- when I came back a few
hours later, the queen was in a giant pile of dead workers at the foot
of the tree.

Post-processing

In between the endless gut dissections, one of the things I've been
learning a lot about this summer is the power of post-processing.

For example, check out this shot of a neat little mantis that my
friend Gabe found. The first image is straight from the camera; the
second, after about 5 minutes of tweaking. To get the second image, I
retouched to get rid of sensor dust spots, tweaked the color
saturation and white balance, and bumped contrast and exposure just a
bit. The difference is startling!

As something of a bonus, I'm finding that this has really focused my
attention on the things you _can't_ change in the 'darkroom;' namely,
focus and composition. Aperture (Apple's photo program) makes it easy
to get rid of sensor dust, but can't recover the end of the mantis's
left antenna, or bring the focal plane forward a mm to where it really
should be. Those imperfections will stay in this image, and
recognizing that is making me a (marginally!) better photographer.

Jungle lesson #1032

Don't leave chocolate half eaten while you get distracted looking for
ants. When you think about it again, a cursory inspection in the
failing evening light may not reveal the hundreds of tiny red ants
enjoying your dessert, which will sting your unsuspecting tongue
enthusiastically on their way down.

Surface tension, part 2

And now for something a bit more abstract. This little Cephalotes
spinosus worker landed feet up in the dissection dish, holding a globe
of water in her legs. This doesn't happen often -- I've dissected more
than a thousand ants so far this summer, and never seen it!

Capturing with the camera what I saw with my eyes was pretty
challenging -- any flash at all washed out the beautiful reflective
colors on the water's surface. For photo geeks, this was taken
handheld with natural light at about 2X on a Canon 20D with 65mm MP-E
macro, at 1/60 sec, f6.3, and ISO 1600.

Yet another spider

And here's another one!

Another spider

Despite my visceral fear of spiders, they make great subjects.
Especially cute little jumping spiders, wrapped up in silk blankets,
waiting for their next houseguest...
