The top-tier journal Nature doesn't often deal in purely phylogenetic research. So when such a study graces their pages we know it's big stuff.
Yesterday, Nature published a 62 gene, 75 species analysis of the evolutionary history of the arthropods. Arthropods, as readers of this…

Plectroctena mandibularis, South Africa
Every now and again someone asks how I get the white background on these sorts of stylized ant shots. Pretty simple: it's a sheet of cheap white printer paper. Overexposing the shot slightly by boosting the flash evens out the white.
I set the ant down on…

It's no secret to anyone with an email inbox that the real internet is shadowed by a fake internet. The fake internet is full of fake blogs, fake web sites, fake discussion forums, and fake emails. All full of real links to real companies who pay someone money to increase their visibility by…

Meinertellidae! It's a jumping bristletail. In California these flightless insects are common around harvester ant nests. I don't think they have any sort of specialized relationship with ants, except perhaps finding the warm microclimate of the mound surface agreeable.
Wings are an ancient…

The notion that insect colonies and their constituent individuals are analogous to multicellular organisms and their constituent cells has been a controversial…

A male western hercules beetle, Arizona.
Meet Dynastes granti. This behemouth of an insect is North America's heaviest scarab beetle, found in the mountains of the American southwest where adults feed on the sap of ash trees. I photographed these spectacular insects a few years ago while living…

Termite mounds visible in Australia's Northern Territory- I've circled three, but dozens are in the image.
Central Illinois still resembles the frozen lifeless tundra, so to get my bug-hunting fix I've been surfing about on Google Earth. Here at -13.066783, 130.847383 I've found something:…

ambient light levels trigger activity in primitive ants
What's unfortunate about this title is that the judgement "primitive" has nothing to do with the research. It is unnecessary. The study is about how one species of ant uses ambient light levels to trigger…

A reader asks:
I also have a MP-E lens with the MT-24EX flash unit. I was curious to know something I didnât see you mention in your recent blog post about this setup.
Could you share any technical points regarding how you achieve the visible backgrounds with that lens? In general, I get very nice…

Given that the current crop of video games is not nearly science-nerdy enough, my friend Rob Mitchell made this graphic as a helpful suggestion to anyone looking to design a new one. I'm just passing it along...

A first glance at Obama's proposed 2011 budget, and I feel relief. Given earlier rumors of a freeze on discretionary spending I had feared the worst, but it seems our government is investing heavily in science as way out of the current economic mess. The National Science Foundation (NSF) may…

According to a new study by Olivier Roux et al in PLoS One, she is spreading pheromones from a previously unknown gland:
Abstract: In Oecophylla, an ant genus comprising two territorially dominant arboreal species, workers are known to (1) use anal spots to mark their territories, (2) drag their…

You may know Michel Gondry as the director of off-beat films like "Eternal Sunshine of the Spotless Mind". Gondry has also made a great number of music videos, including this mesmerizing time lapse of a cross-country drive:

Arachnids (you know, spiders and mites and things) never had much of a presence in my photo galleries. While I could chalk their absence up to an obsessive focus on formicids, the reality is that I'm mildly arachnophobic. Photographing spiders makes me squirm, so I don't do it very often.
Oddly…

I did not expect everyone to nearly instantaneously solve yesterday's termite ball mystery. I'm either going to have to post more difficult challenges (from now on, nothing will be in focus!) or attract a slower class of reader.

...and it's about ants, of course:
The Trailhead Queen was dead. At first, there was no overt sign that her long life was ending: no fever, no spasms, no farewells. She simply sat on the floor of the royal chamber and died. As in life, her body was prone and immobile, her legs and antennae relaxed…

Amblyopone australis: a primitive ant?
Earlier I chastised Christian Peeters and Mathieu Molet for misinterpreting the term "basal" in a phylogenetic context. What was that about?
The issue relates to the classic fallacy of viewing evolution as a linear progression from primitive to advanced.…
