Micro stuff with macro

I've had precious little time to get out and practice shooting with my new Panasonic FZ-50. The other day did offer a window to run over to my favorite local patch, Kiwanis Park on the Scioto River right here in Columbus. I am very pleased with the camera, especially the FL-360 flash tower that I got with it. The versatility of this flash far exceeds the camera's built-in flash, and the potential seems great. Following are some miscellanea shot with this setup.

No macro stuff here, but this shot shows the site. The color representation seems more vivid than with my old FZ-30, and I am really pleased with how scenic landscape shots come out. That's the State Rte. 161 bridge in the background. The large yellowing patches of vegetation in the river, such as in the foreground, is Water-willow, Justicia americana, a plant very important to stream ecology.

Up close with a Black-legged Meadow Katydid. Tiny and grasshopper-like, this male is perhaps an inch long. You've heard them. They are abundant, and singers create a dry shuffling trill. The antennae - cut off in this photo - are extremely long, probably three times the length of the insect's body.

Rear view as he clambers about. I've found that with a bit of patience, insects will resume their activities once they recover from the shock of having some giant humanoid bumble into their space. These singing insects are sharp of eye and ear, and will detect you from afar and clam up. Some effort is often required to track them down. The little dual prongs jutting from the katydid's posterior are the cerci, little claspers that hold the Missus in place while they make little katydids.

A leaf blade of Rice Cut Grass, Leersia oryzoides. Many people first notice this common native grass by feel rather than sight. If you look closely along the edge of the leaf, you'll see tiny teeth projecting outward. There are more of these stiff teeth along the midrib of the leaf, and they are quite sharp. Walking through a patch of cut grass in shorts can create lacerations significant enough to draw blood.

Like little armless round-headed aliens, the inflorescence of a Common Dodder plant surges from its host plant, a Dotted Smartweed, Polygonum punctatum. Dodders are not particularly easy to identify to species, but simple to recognize to genus. This one is Cuscuta gronovii, our most common species. It often forms large tangles over its host plants, and as it ripens takes on the look of masses of yellowish-orange spaghetti. Dodders, once germinated from their seed, quickly clamber up a suitable host plant. Once they have sufficiently imbedded themselves into the host via suckerlike rootlets known as haustoria, they break connection with the ground and become completely parasitic on the host. As all nutrients are derived from their victims, dodders lack chlorophyll, and normally kill the host over time.

A Harvestman, or "daddy longlegs". As a friend of mine says, these odd spider allies look like a tiny potato that someone stuck legs into. This one appeared to be napping, and was not put off by my close approach. I have noticed that they appear much more active at night. Harvestman are roving hunters, engaging in seek and destroy patrols. Any hapless tiny critter that they encounter may be snatched up and eaten.

I look forward to more experimentation with my new camera and flash.


New words to learn--haustoria--and "holding the missus in place" ...this post is vintage McCormac, and I love it.

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…
