Mark your calendar. The 26th annual Insect Fear Film Festival will be held February 28th at the University of Illinois at Urbana-Champaign. This year's theme is "Centipede Cinema".
The film festival is legendary. I've heard about the event for years, and its lineup of bug flicks, live displays, and art contests have received widespread media coverage. Now that I live in Champaign I'll be able to attend my first one.
The announcement:
The Insect Fear Film Festival - scaring the general public with
horrific films and horrific filmmaking since 1984

awild | February 2, 2009Among the least understood technical aspects of photography, at least for novices, is aperture. Yet aperture has profound effects on the resulting image. Consider the following series of photos, each taken with a macro setup of an MP-E lens on a Canon dSLR camera, focused at the foremost tip of an ant head head shot at increasingly smaller apertures:

Most lenses contain a diaphragm that can constrict from full open down to a little hole, controlling the amount of light that travels through the lens on its way to the film or sensor. The size of the hole is called the…

Explaining the evolutionary tree of life is always a tricky proposition, as narratives are inherently linear but evolution spirals outwards in countless messy directions at once. To tell a story from the tangled bank requires picking a single thread and following it, yet it is precisely our tendency to follow single threads that causes so much misunderstanding of how evolution works.
Attenborough grapples with the problem using an animation that permeates the video, showing graphically the complexity of an ever dividing tree in the background as he traverses time from ancient to modern. …

awild | January 29, 2009Pheidole moerens, major worker, Louisiana
Pheidole moerens is a small, barely noticeable insect that travels about with human commerce, arriving without announcement and slipping quietly into the leaf litter and potted plants about town.  As introduced ants go, P. moerens is timid and innocuous- it's certainly no fire ant. The species is now present in the southeastern United States, a few places along the west coast, and Hawaii. Conventional wisdom suggests that P. moerens originated in the Greater Antilles, but even though the ant was first described from Puerto Rico a century ago…

This young black widow (Latrodectus hesperus) set up shop above the nest entrance of a colony of Pogonomyrmex harvester ants. It's an all-you-can-eat buffet, allowing the spider nearly unlimited pickings as the ants come and go.
The spider's mottled coloration is typical of young widows; they don't acquire the striking black and red warning garb until maturity.

Postdoc Scott Solomon has arrived here at the Smithsonian to work on the systematics and phylogenetics of Trachymyrmex and Acromyrmex ants and fungi. Scott has spent a fair amount of time collecting in South America, but we want to be sure that we have an exhaustive representation of species as well as multiple examples of species from across their ranges. Â To that end, we're contacting folks to inquire about whether they might have Trachymyrmex or Acromyrmex specimens that we can use in this project, particularly from undercollected localities.
Ideally, we require…

I have begun a one year postdoc molecular project focusing on the species in the Solenopsidini tribe with Ted Schultz and Seán Brady at the Smithsonian, Washington DC. Due to the vastness of this tribe and its taxonomic challenges, I want to thoroughly sample each genus currently classified in the tribe as well as those that were historically classified as solenopsidines. ANY samples that belong in the genera listed below are needed. I have also included a species âwish listâ that will complement a morphological study done by Juanita Rodriguez and my dissertation…

In thinking about where the myrmecological community ought to devote resources in the age of genomics, it occcured to me that putting some numbers on where researchers have previously concentrated their efforts might be useful. So I went to BIOSIS previews and quantified the number of publications in 5-year intervals from 1984 to 2008 recovered under searches for various well-studied ant species (methods and full data here). Here's what I found:
Number of publications 1984-2008…

The Giant Tiger Beetle Amblycheila cylindriformis is a tank of an insect, at 35mm in length the largest tiger beetle in North America.  Unlike the more familiar day-active Cicindela tiger beetles, the flightless Amblycheila lumbers about at night, catching hapless insects in its massive jaws.
Photographing Amblycheila was difficult on account of the insect's shiny integument, so I used a white-lined cardboard box as a miniature studio. A strobe fired into the box produced a diffuse white light.
On display at the Audubon Insectarium.

From time to time I see people argue about the backgrounds in macro images, and about how dark backgrounds donât look natural âwhatever the heck that means. Seriously whatâs natural about macro photography? Do you see all the detail in a beeâs compound eye or the tiny âhairsâ that cover most leaves without the aid of some sort of magnifier?
I think Dalantech is entirely correct in that arguments about the naturalness of black backdrops are unconvincing. There are many reasons to take photographs, and capturing an animal in a particular…
awild | January 21, 2009I know you're terribly bored with ants, ants, ants all the time here at Myrmecos Blog. So that's why we're bringing you something different. It's an ad from the 60's letting you know about an exciting new product for putting on a few pounds:
For some reason it was lying around the entomology office this morning. Entomology leads to emaciation? Thin people don't attract enough insects? I can't figure it.
