Charismatic Katydids

I've been smitten with the Orthoptera for the better part of a decade. I liked these insects - crickets, katydids, coneheads and their kin - even before that, but didn't make a real effort to learn about them. Then, one day about eight or nine years ago, a woman asked me what was making a metallic clicking sound in a shade tree outside her house. From her description, I recognized the sound as I had heard it too, but I was embarrassed to say that I did not know the causer of the clicks.

It didn't take much research to learn that the mystery clicker was a Greater Anglewing, which is a jumbo katydid and a consummate leaf mimic. I was hooked! From that point, I wanted to know the names of all of the six-legged singers that compose our late summer and autumn symphonies. If you are into birds, as I am, learning the insect songs is great practice for tuning the ear for bird song.

Now, I find myself giving lectures on Orthopteran insects, and taking people afield to learn more about them. Last Saturday night, I led such a gig over at Dawes Arboretum, and our field trip was beyond fantastic. It was as if the insects were jumping from the trees and shrubs into our hands. We got great looks at a number of species, and I would say that the Slightly Musical Conehead was the people's favorite.

The very next day, I was on another expedition, and we found the beauty pictured below. She totally manifests the abundant charisma that defines katydids...

A female Curve-tailed Bush Katydid, Scudderia curvicauda, inspects the tasty skin of her human handler. This animal magically sprang from the grasses and presented herself to the group. Knowing a bit about the habits of these beasts, I set about luring it onto my hand. The larger katydids are often incredibly confiding. All one needs to do is slowly move a hand into the proximity of their antennae. The katydid will tap your skin with its feelers, detect tasty salty skin, and clamber aboard.

Once in the hand, the katydid will begin rasping off the outer epidermal layer of your skin, which kind of tickles. Their jaws are powerful, and every now and then they'll give a decent pinch, but nothing too much. But having one of these animals so near allows for the chance to admire their striking appearance. Note the tricolored eyes and whimsical looks of this beautiful animal.

I knew it was a bush katydid in the genus Scudderia when I saw it, but did not know the species. Females are harder to identify than males; indeed some references say that you must see them in close proximity to their male mate to make a positive identification.

Unless you're friends with Wil Hershberger. Wil literally wrote the book on singing insects, and I sent him these photos for his thoughts. He recognized the animal for what it was, and hence I got a  positive identification.

Speaking of Wil Hershberger, this is his book, which he coauthored with Lang Elliott. It is THE book to have for anyone interested in singing insects. If you aren't interested in this group and pick up this book, chances are you soon will be interested in the Orthoptera. I highly recommend The Songs of Insects, and you can get it RIGHT HERE.

We have another wonderful Orthopteran asset right here in Ohio, in the form of Lisa Rainsong. No one in this state knows the singing insects better than Lisa does, and she has started a wonderful blog devoted to our music-making bugs and Nature's other songsters. Check it out RIGHT HERE.

The other day whilst I was whacking down the grass in the yard I must have seen 8 of those little katydids. Usually I don't see very many.

Great article Jim. Do you know if mosquito spraying impacts katydids? We've got a great deal in Worthington, but I noticed a spraying truck last week. There seemed to be much less singing the next night, but my survey was not at all scientific.

Don't know, Paul. But it wouldn't surprise me if orthopterans were part of the collateral damage of ill advised and foolish indiscriminate mosquito spraying.

Best part of late summer is listening to the katydids as I fall asleep!!

Good timing on this article. I saw a different katydid at Bedford Reservation recently. It was on the railing at Bridal Veil Falls, which made taking a pic rather easy.

If you scroll down to the Comments on this image you can see another katydid I saw a couple of years ago in the same area.

If you would be kind enough to look at some other images in my Photostream...Can you ID the yellow and the brown mushrooms in my Photostream?

I have consulted a few books and websites. Fungi ID is not easy. But, I do like finding mushrooms in the parks.

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…

Snowy owl photography tactics - and things NOT to do

A gorgeous juvenile female snowy owl briefly catches your narrator with its piercing gaze. It's doing its Linda Blair/Exorcist trick - twisting its head 180 degrees to look straight behind. Owls have 14 neck vertebrae - double our number - which allows them such flexibility.

These visitors from the high arctic have irrupted big time into Ohio and adjacent regions, with new birds coming to light nearly every day. Probably 80 or so have thus far been reported in the state, and some of them have stuck around favored spots and become local celebrities.

I went to visit one of these birds this morning - the animal above, which was found last Friday by Doug Overacker and Julie Karlson at C.J. Brown Reservoir near Springfield. In the four days since its discovery, many people have visited as is nearly always the case when one of these white wonders appears near a large population center or is otherwise very accessible.

And as is always the case, people want to photograph the owls. And th…
