Flight of the (tricolored) bumblebee

A typical beach scene at Wilderness State Park at the extreme northwestern tip of Michigan's lower peninsula. The mighty Mackinac Bridge, which crosses over the Straits of Mackinac into the upper peninsula, can be seen from this spot.

Beach-walking here is always interesting, especially for a natural philosopher such as myself. One is serenaded by various boreal warblers and other songbirds from the adjacent coniferous woodlands. Scads of mergansers, cormorants, terns, gulls and other waterfowl gad about offshore. If one is really lucky, a Piping Plover might be spotted - they nest locally.

For those with a botanical bent, it can be difficult to keep one's eyes to the sky, what with all of the interesting flora. The rocky beach was liberally strewn with the magenta blossoms of bird's-eye primrose, Primula mistassinica. Nearby mossy hummocks, partially shaded by arbor-vitae, harbor the diminutive calypso orchid, Calypso bulbosa. The latter was a major target for me, but alas, the late spring conspired to delay its blooming and I'd probably want to be heading back north this weekend to see it (which won't be happening).

But what would you know - in spite of all the avian and botanical distractions, it was a bee that caught my eye. Not long after venturing onto the beach, an utterly stunning bumblebee shot by, and the chase was on.

I'll have you know that I invested a good hour of my life to make these images, and that nearly all of the dozens of images that I made were no good. It was a windy day, and the dwarf willows upon which the bees were feeding blew about like rice paper in a hurricane. To obtain any semblance of a decent shot, I set my camera to shutter priority at 1/1600, and had to use one hand to hold the willow sprig steady.

Anyway, the little beauties are tricolored bees, Bombus ternarius, sometimes known by the (better) common name of orange-belted bumblebee. This is a bee of northern climes, ranging throughout much of Canada and south into the northern states. I had never seen one in the flesh, but knew it instantly because of its distinctiveness. In photos, the bee looked to be an entomological wonder, and I was not disappointed in the least upon finally making its acquaintance.

The tricolored bumblebee looks good from any angle, especially from the back. That fuzzy orange belt should give anyone pleasant pause, and I don't consider a single second of my apian adventure wasted time.

Insofar as I know, this bumblebee doesn't occur in Ohio, at least with regularity, but I will gladly accept correction on this point. At least I've never seen one, and I tend to give winged pollinators more than a casual glance. I can report that these tricolored bumblebees were the most difficult bumblebees to photograph of any species that I've encountered. Once spooked, which was easy to do, they would roar off, make a few circles, and shoot quickly out of sight. Chasing one was impossible, but fortunately a fair number of these animals were present and it only required inspecting a few flowering willows to turn up another.

Bumblebees are nearly perfection when it comes to cross-pollination.Note the pollen adhering to this specimen as it works over the flowers of this willow. Also note the tiny orangish spot in its yellow "fur", just above where the wing meets body. I believe that is a mite, and if you scroll up and look at the first bee photo, you'll see a few others near that bee's eye. Mites are ubiquitous on all manner of flying insects, but it takes a fairly heavy duty macro lens to pull them in.

I chuckled at the Latin name-Bombus. Somehow, that just "fits"

I've never seen a bee like this in that area, even with all the time I've spent up there. Thanks for the education Jim! Larry

Are you familiar with http://www.bumblebeewatch.org/ ?

They are seeking photos and records of sightings of all bumble bee species. They'd appreciate some of these beautiful photos!

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…
