"Halloween" Spider

A colorful female Marbled Orbweaver, Araneus marmoreus, clambers around on a Clearweed nettle. At this time of year, Marbled Orbweavers are one of our most conspicuous spiders. Big and brightly colored, they sport the colors of Halloween, and that color pattern and their conspicuousness in late October causes them to sometimes be called the "Halloween Spider".

For as big and bright as they are, these orbweavers can be quite bashful. We spotted this one on a recent excursion, and of course instantly moved in to make photos. As soon as our party started crowding her, she zipped under a twig and did her best to blend in.

Most spiders are actually pretty mellow, although nearly all do have fangs and can bite if pushed hard enough. This one was remarkably tolerant of our gentle fingertip prods, as we tried to pose her.

As big and plump as this one was, I suspect she is full of eggs. That'd also explain why she was on the prowl during daylight hours - she was probably looking for a good place to deposit her egg case.

Marbled Orbweavers normally are nocturnal, and like most of the rest of their orbweaving ilk, make neat circular webs. This is one the species that often employs a "signal line". You can see a photo of another orbweaver doing just that RIGHT HERE.

Ironically, just today Bobbi Meldahl sent along a great photo of another Marbled Orbweaver that was frisking about the Hocking Hills. Her photo really shows the brightly colored bulbous beauty of these very cool spiders.

Hope one crosses your path soon!

In Bobbi's photo it looks like a pumpkin with a kitty face carved into it. :3

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…
