More gigs for the Pink Katydid

I finally had the opportunity to work with the now famous pink Amblycorypha katydid known as "Pinky", and get some respectable images. Scroll back to a few earlier posts that I made if you want to learn more about it. Above, our star poses on the leaf of a native agrimony, Agrimonia gryposepala, which provides a nice backdrop for her nearly preposterous pinkishness. Little did Jan Kennedy know, I suspect, what a sensation this bug would become when she found it in a meadow at Killdeer Plains Wildlife Area.

Wil Hershberger, world class authority on singing insects and the Orthoptera, and a heckuva nice guy should you ever get the opportunity to meet him. He and Lang Elliot produced the book The Songs of Insects, and it is sensational, as is the CD of sounds that is included. Look closely on his hand and you'll see our pink protagonist, hanging with the Man himself.

Despite many years of active field work and specific searches for all of eastern North America's singing insects, Wil had never seen one of these pink katydid forms. Until yesterday, that is, when he made the trip to Columbus from West Virginia to meet the pinkster. Wil is also an expert photographer and got images that are dazzling, as well as video footage.


A short video of the katydid, surrounded by fawning paparazzi.

As the little bubblegum-colored beast can't yet fly, we had few qualms about posing her outside in natural vegetation for photo ops. She's a tremendous jumper, though, and if provoked can outleap Superman. But, I learned a katydid herding technique from Wil. Should you wish to prod one into a new more photogenic pose, don't use your fingers. They react badly to the oils and salts in your skin, and will take a flying leap. Rather, just find a nice feather if one is handy, and push them around with that.

Her eyes are crazy, sort of a bluish-white marbled color that contrasts interestingly with the outrageous body coloration. Note the short wing buds, just aft of the armored plating known as a pronotum. Males have a file and scraper system on the forewings which they rub together to produce sound. Fossil evidence of Orthopterans with the the "singing" parts preserved dates back 360 million years, making these insects likely the first organisms to evolve the ability to intentionally create sound.

Today, Pinky began to show signs of molting, and I am curious to see what she looks like tomorrow morning. We are hopeful all goes well with her and she successfully molts out of this last instar stage and into her final adult form, replete with large wings.

A bit of potential bad news. Really bad news if you are the katydid. Wil noticed a slight mark that appears to be the incision wound caused by a parasitic wasp. You can see it by looking on her lower body, just in front of where the base of the curved swordlike ovipositor joins the body. The wound looks like a slight pinprick, and if it is indeed the handiwork of a wasp, it's curtains for Pinky, unfortunately.

A great many insects are attacked by parasitic wasps, which use stingerlike ovipositors to inject eggs into the victim's body. There, the eggs hatch into little grubs, which begin to eat the host alive. Finally, like something out of a horror movie, the grubs burst from the hapless host's body, and by that time it is nearly dead. Nature is full of these seemingly horrific relationships, but that's just how it goes.

Even if this is Pinky's fate, she will have been an extraordinary ambassador for insects and the natural world. Her next act is the Ohio State Fair, where she'll be displayed at the Natural Resources area. Should you find yourself down there, stop by and check her out.

One last short vid, showing the curious slow jerky gait that katydids move by; their walk resembles that of an American Woodcock.

You do have pet life insurance on Pinky, right? ;-)

I just heard the sad, but natural, news. RIP, Pinky.

First time I read this post I've really amazed with the color of the insects and I can't believe that there is a insects like that...

The Pinching Beetle, a rather brutish looking bug

The world is awash in beetles, and they come in all shapes and sizes. Few of them can match the intimidation factor of a Pinching Beetle, Lucanus capreolus, though. Those formidable looking mandibles look like they could slice off a finger.

Today was one of those coolly diverse days. I started off down in Fayette County, visiting the farm of a friend. He has restored about 25 acres of wetlands, and the response by the animal community has been nothing short of phenomenal. Blizzards of dragonflies of many species, amphibians galore, and nesting Blue-winged Teal, Pied-billed Grebe, and Sora. Among MANY other things. And all in a short two years. Add water and they will come.

Then, working my way home, I ducked into a Madison County cemetery that has a thriving population of Thirteen-lined Ground Squirrels, and shot images of our native prairie dog. Then, I stopped at a spot along Little Darby Creek, waded on in, and procured some pretty nice shots of various stream bluets and dancers. …

Calliope Hummingbird in central Ohio!

A hatch-year male Calliope Hummingbird strikes a pose. Small but tough, the hummingbird was feeding actively yesterday in 39 F temperatures. It frequents feeders and gardens at a home in Delaware County, Ohio, about a half-hour north of Columbus.

Fortunately, the wayward hummer appeared at the home of Tania and Corey Perry. Tania is a birder, and knew right away that the hummingbird was something special. For a while, the identification was up in the air, which isn't surprising. The Calliope Hummingbird used to be placed in its own genus, Stellula, but has recently been submerged into the genus Selasphorus, which includes Allen's, Broad-tailed, and Rufous hummingbirds. The latter two, especially, are quite similar to the Calliope in subadult plumage. Rufous is the default "vagrant" hummingbird here, with dozens of records and birds turning up annually. There is but one Ohio record of Allen's Hummingbird, from late fall/early winter 2009. Ditto the Calliope Hummi…

Ballooning spiders

Fear not, ye arachnophobes. The subject of this entry is indeed about spiders, but the star of the show is about as cute as a spider can get. And you'll want to know what we're about to learn...

On my recent West Virginia foray, we were strolling down a seldom-used lane, when a bright yellow object caught our eye. It was a goldenrod crab spider, Misumena vatia, on top of a post! Not only that, she - it is a girl - was acting extraordinarily goofy. The spider would stilt up as high as she could go on her legs, weave back and forth, jig side to side, and otherwise engage in what appeared to be spider break-dancing.

Click the pic for expansion, and you can see two columns of silk issuing from her spinnerets. This is an important point, as we set about determining what this non-web-making spider is doing.


So fixated was our spider on her task that she even rejected what would seem to me to be a perfectly scrumptious meal. This little caterpillar climbed rapidly up the post and dire…
