Milkweed program - Wednesday, July 8, Grange Insurance Audubon Center, Columbus.

North America's most iconic butterfly, a Monarch, refuels on nectar during its long journey south. This shot was taken last fall in a planted prairie that was nothing but turf grass three years ago. It now serves as a valuable way station for migrating Monarchs, and scores of other pollinators. This highly urban prairie patch will figure into the tale I'll tell next Wednesday evening.

The downward spiral of the Monarch has brought milkweed plants into a limelight they've never enjoyed before. That's because milkweeds serve as the host plants for the butterfly above - the only plants that the butterfly's caterpillars can eat. Nurseries can hardly keep the stuff in stock. The people have spoken - they want to protect Monarchs. Milkweeds are their ammo.

But milkweeds do FAR more than just service Monarchs. This Butterfly Milkweed, Asclepias tuberosa, is awash in Spicebush Swallowtails, with a few Great Spangled Fritillaries thrown in for good measure.

Next Wednesday evening, commencing at 7 pm., I am giving a talk entitled Milkweeds, Monarchs, and More at the fabulous Grange Insurance Audubon Center near downtown Columbus. CLICK HERE for details. It's free, and all are welcome.

The "and More" part of my talk title will be lived up to. Milkweeds host many other animals, a number of which only use these plants, such as this amorous pair of Red Milkweed Beetles. I will share many milkweed species, one of which is a stunning, state-endangered moth.

The bizarre spidery maroon flowers of a strange vining milkweed, Angle-pod, Matelea obliqua, a rarity in Ohio. It is the only representative of its genus in Ohio.

A whopping big milkweed is the Poke Milkweed, Asclepias exaltata. In sum, there are thirteen species of Asclepias milkweeds in Ohio, and it is a varied lot. However, to a plant they are all beautiful, and incredibly valuable to wildlife.

While showy butterflies garner the lion's share of attention when it comes to milkweed visitors, the plants probably attract more moths. We just don't notice, since many of their visits take place under cover of darkness. This tiny species is a Buck's Plume Moth, and they love milkweed nectar. They're so tiny as to be dismissed as a gnat or mosquito, if noticed at all.

Successful milkweed pollination is synced to powerful bumblebees; lesser creatures beware. This small wasp learned the hard way the perils of entering the sphere of a milkweed flower. It became entrapped, and perished.

I'm going to range through the interesting links between milkweeds and humans, show the varied species and what makes them tick, and discuss some of the fascinating animals whose fortunes are tied, in some cases inextricably, to milkweeds. And end it all with a cool example of something that anyone with a small plot can do to make the world a better place with milkweeds and prairie plants.

Hope you can make it! Again, CLICK HERE for details.

It's a lovely prairie with great diversity!

Does the higher traffic concentration surrounding a highly urban ecosystem have any effect on the mortality rate of the creatures who utilize it? I would think there would be more car strikes.

Not at our site, Jain. The prairie is in the middle of our complex, well away from busy roads, so car mortality is not an issue. Might be at roadside sites but don't know of any studies to bear that out one way or another.

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…
