Epicauta pardalis - spotted blister beetle
Tucson, Arizona
Here's a beetle so toxic it can kill a horse. The horse doesn't even need to ingest the beetle, it just needs to ingest something that the beetle bled on. Blister beetles produce the defensive compound cantharadin- the active ingredient of the aphrodesiac Spanish Fly- which they reflex-bleed out their joints when threatened:

awild | April 3, 2008Back in 2002 when I used the Nikon Coolpix 995 for everything, I would occasionally play around with the camera's very basic video mode. The 995 made small, grainy movies without sound, and most of the videos I took are, well, pretty bad. But the camera had impressive macro abilities, which meant it could shoot ants close-in. Here's a movie of a Dinoponera from the Mbaracayú Forest Reserve in Paraguay:

April is National Poetry Month, and I plan to post one poem per day, every day, this month (If you have a favorite poem that you'd like me to share, feel free to email it to me). Today's poem was suggested by my friend, Professor of Poetry at KSU, Elizabeth Dodd.
The Family Is All There Is
Think of those old, enduring connections
found in all flesh -- the channeling
wires and threads, vacuoles, granules,
plasma and pods, purple veins, ascending
boles and coral sapwood (sugar-
and light-filled), those common…

If you've ever spent time photographing ants the above shot will look familiar: off-frame and out of focus. Because ants are small and speedy, they are among the most difficult insects to photograph. Just capturing an active ant somewhere in the frame can be regarded as an achievement, never mind the more aesthetic concerns of lighting and composition. Yet ants are dominant insects nearly everywhere, and photographers who neglect them are missing out on one of our most important animals. Figuring out how to photograph these tricky insects is well worth the effort. If you can shoot ants,…

I know you all are wondering what happened to me since I have been so quiet today, and the truth is that I am doing all sorts of amazingly fun things as long as possible until my broken wing makes me exhausted from ignoring the pain. At the moment, I am sitting in my very own office (!!) next to Dave Rintoul's in the biology department at Kansas State University in Manhattan, Kansas. (It might interest you to know that this office is much larger than the first apartment I rented in the other Manhattan). I am uploading something close…

Rather than blather on about my Easter Sunday, I'll just share a few images from a morning hike in Tucson's Rincon mountains. Winter rains have given way to wildflowers, and in particular the Encelia brittlebush was spectacular.

Dog walking in natural areas harms wild birds, according to recently published research.
Millions of people walk their dogs every day, and many of them enjoy walking their dogs in natural areas where birds and other wild animals live. Unfortunately, a scientific paper was recently published showing that the presence of dogs, even when they are on a leash in these natural areas, seriously interferes with wild birds' reproductive success and even scares many of them away.

In our front yard we've got a busy nest of Pogonomyrmex rugosus seed harvesting ants. Warming weather brought them out for the first time last week, and every now and again I go out to see what they're up to. Lots of digging, it seems.
Pogonomyrmex is greek for "Bearded Ant", named 150 years ago by Austrian myrmecologist Gustav Mayr for the thick brush of hairs on the underside of the head. Entomologists affectionately refer to these ubiquitous desert insects as "Pogos". What does the beard do?
It's a construction tool, and one that is especially helpful in dry, sandy climates. As anyone…

Strumigenys louisianae stalking a springtail
Tucson, Arizona
Non-native species should make a naturalist's skin crawl, but these ornate little trap-jaw ants are a guilty pleasure. Strumigenys louisianae is among the most widespread of the miniature trap-jaw ants, occurring naturally from the southeastern U.S. to northern Argentina. The desert climate in Tucson is too dry for Strumigenys, but they persist in lawns, gardens, and other places in town where irrigation raises the moisture levels. No one knows when or how they arrived, but it is likely the founding colonies stowed away in…

Apteroloma caraboides (Agyrtidae) - Snowfield Beetle
California
Why would I waste a prime Friday Beetle Blogging slot on such a drab little beetle? Because Apteroloma caraboides does something really cool. Really cold, even. This species inhabits the edges of high-altitude snowfields. They are found in places like these, in the high Sierra Nevada:
Snowfields are an inhospitable environment for an insect, but one that offers animals with good cold tolerance a unique way to make a living. Apteroloma caraboides cruise the easy pickings of less hardy creatures that fall onto the snow…

A long-time reader, Jerry, sent some images for me to feature as the "image of the day". He referred to these as "some friends to help you tend your wing".
Some road construction created some temporary mudflats where many shorebirds found excellent feeding, including this great egret, Ardea alba.

I've got a new series of Dinoponera photographs up at myrmecos.net. Click on the image above to see the gallery.
These giant black insects are the largest South American ants, and although there is at least one Asian Carpenter ant (Camponotus gigas) that's a bit bigger, Dinoponera weighs in as the world's largest stinging ant. They would seem to command a great deal of respect for such distinction, but in reality Dinoponera are rather shy animals.
Because these ants are so large- reaching over an inch long- they open up an array of photographic possibilities that can't easily be done with…

Scaphinotus petersi - Snail-Eating Ground Beetle
Arizona
Ground beetles- the family Carabidae- are a spectacular evolutionary radiation of terrestrial predators. The elegant, flightless beetles of the genus Scaphinotus prefer snails and slugs.
