Those of you who haven't got an ad blocker installed have probably seen this ant floating about in a promotional banner in the ScienceBlogs sidebar: I can't speak for how others react to this image. Most, I imagine, filter it out as yet more clutter on the screen. But for a picture of an insect…

Ectatomma edentatum, Argentina Equipment details: Canon EOS 20D, using an MP-E 65mm 1-5x lens (at 5x), lit with an MT-24EX twin flash diffused through tracing paper. Several years ago, before I became serious about photography, I shot the same species in Paraguay with a little Nikon Coolpix 995.…

The first Earth Day was celebrated on April 22, 1970, and it heralded a new era in the US. The New Yorkerâs Elizabeth Kolbert explains: Among those who seemed unmoved was President Richard Nixon. He avoided the festivities and made no public comment on them. (One of his aides, John Whitaker, later…

Our countryâs food-safety system may leave a lot to be desired, but the New York Timesâ Gardiner Harris reminds us that we should be grateful to the epidemiologists who let us know an outbreak is occurring at all. And it turns out that many of these alarm-sounding professionals work in Minnesota.…

A Brazilian leafcutter ant (Atta sexdens) harvests a leaf while her little sister stands guard against an intrusive photographer. (Incidentally, image searches for this genus return an unnerving mix of terrorists and ants.) Photo details: Canon MP-E 65mm 1-5x macro lens on a Canon EOS 20D. ISO…

Compare these two images, both of the same swarm of mating ants: What's the difference? The lighting, of course. In the first image I stood facing the rising sun so that the insects' translucent wings glowed, while in the second I moved to shoot the swarm from another angle, the sun hitting them…

...these would be the beetles of choice. Onthophagus taurus dung beetles, showing size and horn variation among males. Dung beetles in the widespread genus Onthophagus sport a bewildering array of horns. Not only do the horns of different species vary in shape, size, and the body part from which…

An Amblyopone oregonensis huntress delivers a paralyzing dose of venom to a centipede. This lets the ant larvae consume it alive later, at their leisure. Ow. Ow, Ow. Yes, that is the stinger you see, sunk deep into the head. A cricket is impaled on the mandibles of a Malagasy trap-jaw ant,…

Fire ants aren't the only formicids that have to worry about parasitoid phorid flies. Many species are hosts to this diverse fly family. Below are a pair of photos I took recently near Jujuy, Argentina showing a trio of an unidentified Pseudacteon species hovering over an ant nest. One of the…
