Bullhead Lily

Bullhead Lilies dapple the surface of a blackwater marsh, Seney National Wildlife Refuge, Michigan's Upper Peninsula.

Ohio is truly a crossroads state. Botanical influences collide here: prairies from the west, Appalachian flora from the east, southern migrants via the mighty Ohio River, and boreal plants from the north. There are something along the lines of 600+ state-listed rare plants - species decreed endangered, threatened, or potentially threatened. Many of them are edge of range plants, rare in the Buckeye State, but common, even abundant elsewhere.


That's the case with Bullhead Lily, or for you plants geeks, Nuphar lutea ssp. variegatum. There is only a spot or three in our western Lake Erie marshes where it is known to grow. But not too far into Michigan, I began seeing it everywhere.

It may remind you of a similar plant, one that you'll see far more if you hail from south of the Great Lakes. Spatterdock, Nuphar lutea ssp. advena, is often abundant in quiet ponds, lakes, marshes, and even sluggish river backwaters. That species has very different leaves, though - they are held erect and jutting from the water's surface, whereas the star of this blog has floating leaves.


I love the unusual ball-like flowers of Bullhead Lilies. The photo above shows one at peak bloom; that's about as good as it gets, but they have their semi-ugly charms.

Any plant that creates this much biomass within aquatic habitats is almost surely a keystone species, and the lily certainly is. Fish hide among its stems, especially fry in need of cover lto prevent the bigger fish from making sushi of them.

Frogs sit atop the leaves, snapping at insects. Dragonflies use the plants as landing pads, darting out to make mincemeat of lesser flying beasts. Some of them lay their eggs on the plants, and a few dragons even slice open the tissues and inject their eggs inside.

Other animals, such as Muskrats, will even eat the lilies.

But the aesthetic attributes cannot be ignored. A colony of dark green heart-shaped leaves cloaking the surface of cool marshy waters, with bizarre lemon orbs on sticks thrust out here and there, is a pleasing sight indeed. Especially if you are from the Deep South, where such a plant is a great rarity.

Just wanted to tell you how much I enjoy your blog; I've been reading it for a while now. I am about to leave for my 30th year vacationing in northern MI, so I recognize lots of your recent photos and am looking forward to some hiking and observing. Thanks for such an engaging, helpful blog.

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…
