I am extremely pleased to announce the 2016 BugShot Insect Photo Workshop! The event will be held for the first time in Austin, Texas, and will be instructed by Piotr Naskrecki, John Abbott, and myself. Our 3 1/2 day event will cover basic techniques in macrophotography in the field and in the studio, methods for working with live insects, and advanced techniques in focus-stacking and high-speed flash.
A focus-stacked image of a red imported fire ant, one of many subjects and techniques we will cover in Austin.
As usual, our location is a site of considerable natural beauty, with rustic lodging and classrooms on site, with nearby hotels for those who prefer more upscale accomodation. We will be at McKinney Roughs Nature Park, a 1,900 acre tract of woodlands, meadows, and canyons. These workshops are a real highlight of my year, not just for the nature and the photo nerdery, but for the community of wonderful people that has coalesced around the BugShot events. If you haven’t been yet, you should try to this year. We’d love to have you!
BugShot 2016 Registration
Last year’s California workshop sold out within a week, so if you’re thinking of attending, you may need to sign up quickly.
And now, an excerpt from my second mid-term exam for the BIO 453L class. Good luck!
8. Australia was able control its infamous bush fly problem by importing several species of:
a. Dung beetle
b. Robber fly
c. Orb-weaving spider

9. In your new job as a forensic entomologist, you receive a sample of insects collected by police from a body discovered in a park. The sample contains mostly beetles in the family Dermestidae and moths in the family Tineidae. It is autumn and the weather has been cool. Would you estimate the PMI (=time of death) to be:
a. Within a day.
b. Within 2-3 days.
c. Between 4 days and 2 weeks.
d. More than 2 weeks.
10. Which insect order is indispensable, as cacao’s required pollinator, to the production of chocolate?

In recognition of the season, I am pleased to announce a Halloween print sale! What does this mean? I have priced 30 images of arachnids, centipedes, and zombie fungi at 70% off, nearly at cost, until November 1. If you’d like to pick up an Arachtober surprise, have a look at the link below:

Will there be an Arachtober surprise? Follow the festivities on Twitter.
Looking for a challenge? Here are a few questions from the midterm examination of my current Entomology course.
29. Which of the following animals’ life cycles is most likely to include a puparium?
a. house fly
b. silkworm moth

d. rove beetle
30. Sclerotization is the process by which:
a. spiracles close to prevent water loss
b. coremata release pheromones as a sexual attractant
c. the exocuticle hardens following ecdysis
d. the wax layer is formed as a barrier to water loss Continue reading →
It’s been a few months since I’ve posted a rollicking internet copyright yarn. Not that there haven’t been infringements. Those are constant. It’s just that most are overly pedestrian- a pest control coupon that’s removed on request, for example. Not worth blogging. This one, however, involves a barely literate YouTube host pretending to be a lawyer, and his messages are simply too bizarre to pass up sharing.
A screen capture of Mr. Dowlatsingh presenting my photographs.
I won’t bore you with the details of the infringement beyond the basics: 6 photographs of driver ants, most with my name cropped out, uploaded twice to a popular YouTube tabloid without being credited or licensed. The infringer responded to my formal copyright notice by committing perjury, claiming to Youtube that he had rights to my work and that my notice was mistaken.
Thinking the rights grab a bold move, I emailed him. Our correspondence follows:

You may remember a recent viral video showing an undescribed predatory ant behavior. It turned out that myrmecologists Christian Peeters and Stéphane de Greef had observed these ants in the field, but they’d not assembled enough data to publish, leaving us all in the dark about how the ants coordinated the amazing millipede-hauling chains.
With a bright internet spotlight on the behavior, Christian and Stéphane returned to the project and have just published a detailed description in Insectes Sociaux. The video alone is worth a thousand words:

I was stung by a bullet ant last week in Costa Rica. On purpose.
How did it feel?
Bearable. Given this species’ fearsome reputation, I was expecting worse. It certainly hurt, though.
It wasn’t just the initial sear from the sting’s penetration, imparting all the sharpness one would anticipate from a relatively large hymenopteran, but the way the pain sank beneath the skin.
The bullet ant has a reputation for feeling like a firearm wound. Having never been shot, I can’t make much of the comparison. I imagine an actual shooting would be far more traumatic, but all the same I understand where the name comes from. A Paraponera sting feels more profound than the average insect sting. Like tissue or bone damage, it is a deep throbbing ache that crescendos over several hours. Unlike a honey bee sting, whose sharpness gives way quickly to a dull itch, the bullet ant’s sting is the gift that keeps on giving. Less a gunshot, I suppose, than the lasting pain following a solid crowbar to the arm. Although bearable, mine still ached when I went to bed 8 hours later. All pain was gone in the morning.
We tend not to make much of where on the body we’re stung, but stings are like real estate. Location, location, location. The forearm is a relatively mild substrate, a safe place to experiment with stings. I was once zinged on the tip of the nose by a common honey bee. Holy bejeezus. I’ll take twelve bullet ants to the arm before I wish to relive that one.
(Special thanks to Andrés Rojas and Erica Parra for planning the session and wrangling the ants! For more gruesome bullet ant
entertainment science, see them and others getting zinged at StingFest 2015).
Plectrodera scalator – Austin, TX
The postdoctoral researchers in Nancy Moran’s lab here at UT have adopted a local longhorn beetle and, for reasons that remain mysterious, named it “Ringo”. I can only hope they weren’t punning on Beetles/Beatles.
Ringo was kind enough to pose for me in the most makeshift of photo studios. Lacking time to assemble a proper studio whitebox, I took the beetle to a small, white-painted room and fired a couple off-camera strobes at the ceiling.
Photo details: Canon 6D, 100mm f/2.8 macro lens, two off-camera strobes.
All prints from Alex Wild Photography’s pollination gallery are up to 70% off during Pollinator Week.
June 15-21 is Pollinator Week.
We should not have to designate a week for this. Coffee, chocolate, raspberries, almonds, melons, tequila, blueberries, and countless other delectables require floral visits by certain species of animals. Usually, insects. If you like any of these things, you should already appreciate the importance of healthy, diverse ecosystems.
But apparently not many people recognize where food comes from, or even that flowers only exist because of insects. So here we are: Pollinator Week.
The best way to celebrate Pollinator Week- while sipping coffee & enjoying raspberry-melon tart- is to draw up plans to rip out your boring lawn and replace it with pollinator-friendly native flowers. You may also write your congressperson (if you have moved on to tequila at this point, I wouldn’t blame you) to demand protection of the vanishing natural habitats where pollinators live.
The prairie garden I begrudgingly left behind when moving from Illinois to Texas. We did take the cat, though.
Of lesser impact, I have priced my entire pollination gallery at near-cost sale rates for the week. If you’d like to pick up a 5×7″ print for as little as $3.99, have a look:

Anyway. Happy Pollinator Week. Get your hands dirty.
