Handsome Trig

A few of us had a fantastic field excursion yesterday, which included observation of one of our rarest orchids, an incredible caterpillar, and other noteworthy finds. I've got some nice photos of all of that, but first, and hot off the presses, is something that you've likely got in your own backyard.

My office is in a very urbanized part of Columbus, but the compound includes a patch of "wildness" in the form of a small wetland surrounded by some trees and brush. For a while now, I've noticed the vocalizations of myriad tiny crickets known as trigs emanating from the bushes. So today, I hauled the camera rig out there and in short order found one of these cool little crickets.

The photo above offers a size scale. Those are the leaflets of a white ash, Fraxinus americana, and our little trig can be seen at the base of the center right leaflet. Not much to it.

Move in close and the trig becomes an animal of remarkable beauty. There are perhaps a dozen species of trigs in eastern North America, with most of them being found in Florida and the extreme southeast. Ohio harbors perhaps a half-dozen, but two species are widespread and ubiquitous: Say's trig, Anaxipha exigua, and our featured species, the aptly named handsome trig, Phyllopalpus pulchellus.

Up close and seen well, the handsome trig is like a miniature work of art. The reddish head and thorax contrasts sharply with the glossy black abdomen. The creature is shiny, as if it has been freshly shellacked. This animal is a female, as evidenced by that scimitar-shaped ovipositor jutting from its posterior, so it was not one of the singers that originally drew my attention - only males "sing".

The two paddle-tipped appendages affixed to her snout are called palps, and handsome trigs are constantly checking the substrate with them. In fact, the scientific name translated means beautiful leaf feeler in reference to its habit of patting the leaves with those curious appendages.

Like nearly all of their Orthopteran brethren - the singing insects - male trigs deliver song by rapidly rubbing their wings together. This species is noted for often singing from the depths of rolled leaves, which act as an echo chamber and amplify the volume of their sound. Handsome trigs create a rather dry, rattling rapid trill and they sing throughout the day. The song can be remarkably loud for such a miniscule creature: when I found the female in these photos, I had been triangulating on a male in song, and at certain points its trill was quite loud indeed.

Terrific post Jim. Smashing photos too. You are getting very good with the new camera set up.
I am so glad that you linked to the song. It is wonderful to have people know what these amazing creatures sounds like.

Thanks for making that wonderful website available to us all, Wil! And for all of your recordings of those songs. I'll look forward to seeing you in a few weeks in Adams County.

Saw these for the first time today and immediately recognized them tanks to your blog keep up the great posts on these obscure but interesting guys.

This post was great Jim. It helped us figure out a P. pulchellus recently posted to iNaturalist:

Cheers, Matt

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…
