Tallgrass Prairie Adventures

 “Let us go on, and take the adventure that shall fall to us.” — C.S. Lewis

******

If there’s one phrase my family knows I can’t stand, it’s this one: “Killing time.” Why? Time is precious. It’s irreplaceable. Each day is an adventure, if you let it be so. Why waste a moment?

SPMA72819WMONE.jpg

I think of this as I walk my dragonfly monitoring routes on the prairie this week. The wind has come up. Instead of gazing over my head for patrolling green darners and black saddlebags, I’m looking lower, in the grasses and prairie wildflowers. There, many of the regular high flying dragonflies hunker down, sheltering from the breezy heat.

Floweringspurge72819WM.jpg

Each season, dragonfly monitors—people like you and me—go to a city park, prairie restoration, forest preserve pond, or local wetland with the intention of regularly collecting data about Odonates. Monitors—dragonfly chasers—spend a good chunk of their summer hours in mosquito-filled areas, counting dragonflies and damselflies and making hash marks on a clipboard. We note what species we see, and how many of each species appears on a certain day in a particular place.

RattlesnakemasterSPMA72819wm.jpg

It sounds a little nutty, perhaps, to spend our days counting insects. But dragonflies and damselflies are a good thermometer for the state of our waterways. Their numbers and species diversity have messages for us about the health of our natural world. All we have to do is listen. Pay attention. Show up.

Speaking of thermometers: It’s hot. Sweat trickles between my shoulder blades. I check my phone and see the temperature is 88 degrees. The relative humidity of the Midwest makes it seem even hotter, keeping most visitors off of the prairie trails.

The dragonflies, which maintain body temperature through thermoregulatory behavior, have various gymnastics to help them stay cool.  This female eastern amberwing dragonfly below is obelisking.

EasternamberwingfemaleobeliskingWMSPMA72819.jpg

By positioning her abdomen straight up, she reduces some of the direct summer heat hitting her body. Sometimes, you’ll see dragonflies point their abdomens downward for the same reason. Or, if it’s cooler, they’ll use their wings as solar collectors, like this 12-spotted skimmer below. Gathering sunshine.

12spottedskimmerGEBackyard719.jpg

This season, I find the blue-fronted dancer damselfly population has erupted out of all imagining. I walk, and I look, and I try to keep track of what I’m seeing. Hash mark, hash mark, hash mark… . I can barely keep track of them, emerging from the grasses on both sides of the prairie trail; a virtual ambush of bright blue insects. Under my feet. Hovering knee high. Blue-fronted dancer damselflies everywhere! Hash mark. Hash mark. I finally quit tallying them at 88 individuals.

BluefrontedDancerSPMA7519WM.jpg

So much dazzling blue! The danger is that as I see so many of one species, I overlook some of the other species that aren’t as prolific. Like this violet dancer, mixed in with the blue-fronteds.

violetdancer6718SPMAwm.jpg

Or an American rubyspot damselfly, hanging out by the stream.

AmericanrubyspotSPMA718WM.jpg

Damselflies are so darn tiny. Part of the day’s adventure is to slow down and really look. Carefully. Closely. But I’m always aware of what I’m missing, even as I see so much. All these incredible dragonflies and damselflies! But–that bee over there. What species is it? And what about that butterfly? What’s moving in the grass by the stream? The July prairie explodes with wildflowers all around me as I hike. How can I focus?

NGFFKNOBCCarea2018WM.jpg

It’s easy to be diverted. On one route,  I narrowly avoid stepping on a bee fly sunning itself on the gravel two-track.

Bee fly SPMA72819WM.jpg

On another trail, I kick up little puffs of butterflies—maybe pearl crescents? Tough to ID. They rise, then settle back into the clover as I pass.

Pearlcrescent?SPMA2018WM.jpg

I stop to watch a ruby-throated hummingbird swoop across the trail, then hover, sipping nectar from the dark reddish-brown flowers of a tall late figwort plant, towering over my head.  I didn’t know hummingbirds visit these tiny blooms! In the gusty breeze, the oddball flowers rocket wildly back and forth, but the hummingbird maneuvers right along with them. Later, I visit the Prairie Moon Nursery website and read more about this wildflower’s value to butterflies, bees, and—yes—hummingbirds. Who knew?

Latefigwort72819SPMAWM.jpg

There’s always something different and exciting to learn as I walk my dragonfly monitoring routes on the prairie. Always a small adventure of some sort, waiting to happen.

In rain-rutted puddles, bullfrogs leap across the water with an EEK!”

American bullfrog NG71519WM.jpg

The common yellowthroat sings his wichety-wichety-wichety from the walnut tree by the wooden bridge over Willoway Brook. I inhale the scent of a hundred thousand wildflowers and grasses; the smell of prairie soil that’s alternately been baked in a hot summer oven and soaked with rain.

As I finish my route near the stream, a red-winged blackbird hovers menacingly over my head, daring me to come closer. Are they still nesting? Must be! He shrieks loudly as I cover my head with my clipboard—just in case—and hurry a bit toward the path leading to the parking lot.

CulversRootSPMA2017WM.jpg

So much to think about. The writer Paul Gruchow once observed, “Curiosity, imagination, inventiveness expand with use, like muscles, and atrophy with neglect.” One of the pleasures of dragonfly monitoring is the practice of paying close attention to everything on the July prairie. Flexing the muscles of my imagination. Resisting the urge to become jaded and cynical—all too easy in the world we find ourselves in today. Trying to choose where I focus.

WildquinineSPMA72819WM.jpg

Even a simple hike on the prairie, counting dragonflies, can be an adventure. The writer Annie Dillard penned one of my favorite quotes: How we spend our days, is, of course, how we spend our lives.  I think of this as I watch a black saddlebag dragonfly cruise over my backyard prairie patch, or admire the way the cup plants cradle water in their joined leaves after a torrential downpour, inviting goldfinches to take a drink. I try to ask myself regularly: How am I spending my hours? How am I spending my life?

Every day I struggle to be intentional. To make room for curiosity. Imagination. The life of the spirit. The poet Mary Oliver wrote, When it’s over, I want to say: all my life/ I was a bride married to amazement/ I was the bridegroom, taking the world into my arms.

NG2018summerWM.jpg

Instead of “killing time,” I want to cultivate a sense of wonder. To look at every moment as an adventure. To make room for reflection. To walk, and always—always! —be astonished at what I see.

And how can we not be astonished? Look at those dragonflies, those wildflowers!  Listen to that birdsong. Watch the tallgrass ripple in the breeze.

What a beautiful world.

British writer C.S. Lewis (1898-1963) penned the opening words in this blog from The Chronicles of Narnia, a series of classic children’s books. My favorite book in the series (although it is tough to choose!) is Voyage of the Dawn Treader. Lewis was a contemporary and friend of J.R.R. Tolkien, and part of a writers group known as The Inklings. The books are great for read-aloud, if you have children or grandchildren elementary age and up.

Minnesota writer Paul Gruchow (1947-2004) who wrote one of the quotes that appears in this post, is one of my favorite writers about the natural world. If you haven’t read Gruchow, try Journal of a Prairie Year, or Grass Roots: The Universe of Home. Both terrific reads. I also love his Boundary Waters: The Grace of the Wild.

The late poet Mary Oliver (1935-2019) penned the beautiful poem, When Death Comes, quoted at the end of this post.

Summer Magic on the Tallgrass Prairie

“May I not be permitted…to introduce a few reflections on the magical influence of the prairies? Their sight never wearies…a profusion of variously colored flowers; the azure of the sky above. In the summer season, especially, everything upon the prairies is cheerful, graceful, and animated…I pity the man whose soul could remain unmoved under such a scene of excitement.” ——Joseph Nicollet, 1838

*****

I followed Chance the Snapper—Chicago’s renegade alligator—south to Florida this week.

Captiva Sunset 72119WM.jpg

The tallgrass has often been compared to the ocean, and it’s easy to see why. As I sit on the sand under the hot sun, the ripples on the Gulf remind me of the wind-waves that pass through the spiking grasses and wildflowers.

SPMAinJuly719WM.jpg

It’s difficult to be away from the prairie, even for a few days in July. So much is happening! It’s a magical time. The gray-headed coneflowers pirouette into lemon confetti.

grayheadedconeflower71619SPMAWM.jpg

Purple and white prairie clover spin their tutu skirts across the tallgrass; bee magnets, every one.

Purpleprairiecloverbee-SPMA2017wm.jpg

Rosinweed’s rough and tumble blooms pinwheel open. Rosinweed is part of the Silphium genus, and perhaps the most overlooked of its more charismatic siblings.

rosinweed719SPMAWM.jpg

Cup plant, another Silphium sibling, is also in bloom. as are the first iconic compass plant flowers. Prairie dock, the last of the Silphiums to open here in Illinois, won’t be far behind.

The last St. John’s wort blooms seem to cup sunshine.

stjohnswort719FKAPGlenviewWM.jpg

The smaller pale blooms, like llinois bundleflower…

illinoisbundleflower719WM.jpg

…and oddball wildflowers, like Indian plantain, add complexity to the richness of the July prairie.

indianplantain719KFAPGlenView719WM.jpg

Wild bergamot, or “bee-balm,” buzzes with its namesake activity. I’m always astonished each year at how prolific it is, but this season, it floods the prairie with lavender. Wow.

beebalm719SPMAWM.jpg

The scientific name for bee balm is Monarda fistulosa; the specific epithet, fistulosa, means “hollow” or “pipe-like.” If you pay attention to a single flower in all its growing stages…

beebalmSPMA719WMbud.jpg

….its intricacy will take your breath away. Look closer. Like fireworks!

IMG_9835.jpg

I love to chew its minty leaves; a natural breath freshener. Bee balm’s essential oil, thymol, is a primary ingredient in natural mouthwashes. Tea made from the plant has also been used as a  remedy for throat infections; its antiseptic properties made it historically useful for treating wounds.beebalm719SPMAWM

The hummingbirds and hummingbird moths, as well as the bees and butterflies, find it irresistible.

Not only a useful plant, but beautiful.

beebalmandsunflowersSP2013WM.jpg

The air reverberates with sound on the July prairie: buzzing, chirping; the sizzling, hissing chords of grass blowing in the wind. Overhead, ubiquitous honking Canada geese add their familiar notes.

GeeseBelmontPrairie2919WM.jpg

In Florida, ospreys wake me each morning with their piercing cries. I see them soaring over the tallgrass prairie occasionally at home and at Fermilab’s prairies down the road in Batavia, IL, where they’re a rare treat. Here in Florida, they’re just another common note in the island’s soundtrack.

ospreyCaptiva72019WM.jpg

It’s bittersweet to leave the tallgrass prairie in July for a week and miss some of its seasonal magic. The wildflowers are in full crescendo. The grasses unfold their seedheads and head skyward. The slow turn of the season toward autumn begins. You see it in the change in dragonfly species on the prairie, the sudden appearance of bottlebrush grass and Joe Pye weed flowers. To leave the Midwest for even a few days is to miss a twist or turn in the prairie’s ongoing story. Miss some of the magic.

Obedient plant backyardprairieWM GEIL2018.jpg

But displacement gives me perspective. A renewed appreciation for what I’ve left behind.

The magic will be waiting.

10 Reasons to Hike the July Prairie

“Stuff your eyes with wonder. Live as if you would drop dead in ten seconds. See the world.” — Ray Bradbury

*****

Hot. Humid. Did I mention, it’s hot?

kentfullerairstationprairie71319WM.jpg

So many reasons to stay inside with the air conditioning on, preferably while sipping a cold beverage.

WMGreen bottle fly and Peck's Skipper Ware Field MA 71319.jpg

And yet.  This is one of the most beautiful months on the tallgrass prairie. A new wildflower species seems to open—in vivid technicolor—every day.  Monarchs float like magnets toward milkweed. Tiny Halloween pennant dragonflies dazzle in their dance with the grasses and sedges.

halloweenpennantfemaleonsedge71419SPMAWM.jpg

Big bluestem shoots up, over our heads now in the wetter places, ready to unfurl its turkeyfoot at any moment. Switchgrass shakes out her seedheads. Compass plants burst into their first sunshine blooms.

Prairie cinquefoil’s clusters of flowers appear as if by magic. Invisible, until bloom time.

prairiecinquefoilSPMA71419WM.jpg

Inhale the smell of crisp mountain mint; the tang of bee balm. Listen! Is that a common yellow throat, yo-yo-ing its summer song? July is passing. Don’t miss it!

Not convinced?  Here are 10 reasons to hike the prairie this week. Let the countdown begin.

#10. Hummingbird moths, such as this snowberry clearwing, zip from bee balm bloom to bee balm bloom.

WMsnowberryclearwin hummingbird sphinx moth SPMA71419.jpg

#9. Rare plants, like this eastern prairie fringed orchid are no less beautiful for being just-past peak. Plus a bonus lady spotted beetle.

WMSpotted Lady Beetle with Eastern Prairie Fringed Orchid 7152019.jpg

#8. Meadowhawk dragonflies. The Japanese haiku poet Basho wrote of the red Odonates: “Crimson pepper pod/add two wings/darting dragonfly.” Perfect.

July’s Prairie Patterns

“The world is a confusing and turbulent place, but we make sense of it by finding order… . This makes us all pattern seekers. “– Philip Ball

*****

High heat and cool breezes; thunderstorms and calm mornings. From my hammock overlooking the backyard prairie patch, I’m astonished at the rapid growth of plants under the hot sun, watered by frequent rain showers. I swear I saw cup plants grow an inch right before my eyes! Anything seems possible in the bright light and blue skies of July.

SpMA7519WM.jpg

As I swing in my hammock, I’m reading a new book from University of Chicago Press: Patterns in Nature.  It’s a revelation. As an art and journalism student in my undergrad years, I avoided math as much as possible. Now, I’m discovering the beauty of mathematics on the prairie. Symmetry. Fractals. Surface tension.

So many different combinations of patterns in July! I’ve always been intrigued by patterns in nature. But I didn’t understand much about what I saw.

MonarchcaterpillarSPMA7819WM.jpg

Paging through Philip Ball’s book, I begin with symmetry, which Ball says, is at the root of understanding how patterns in nature appear.

It’s an eye-opener.

BluefrontedDancerSPMA7519WM.jpg

Ball notes that “Bilateral symmetry seems almost to be the default for animals. Fish,  mammals, insects, and birds all share this attribute.” I see this in the blue-fronted damselfly above; in the mirror-image wings of a skipper butterfly below. Divide them in half and each side is essentially identical.

SkipperSPMA7519WM

It’s evinced in the reversed haploa moth, barely visible, deep in the tallgrass.

Confused Haploa Moth SPMA7819WM copy.jpg

There is bilateral symmetry in a bison’s skull, with a few imperfections.

CROSBYWM-losssecondarybisonskullpeltNachusa2017 copy.jpg

Or a monarch’s wings, even when tattered and worn.

monarchonrattlesnakemasterSPMAWM.jpg

Who wouldn’t marvel at the folded, paired symmetrical wings of the male violet dancer damselfly?

Male Violet Dancer SPMA 7519WMsmaller copy

Once you begin looking for patterns in the natural world…

CROSBY-WMsecondaryphototransitionsSPMAgray-headedconeflower2017 copy.jpg

…you see them everywhere.

spider-Brown CountyWM2017.jpg

Fractal geometry, Ball writes, is said to be “the geometry of nature.” Fractals? What’s a fractal?  “Don’t know much algebra…,” sang Sam Cooke in his classic, “(What a) Wonderful World.” Yup. But I want to know more.

Ball boils it down to this: Look at a tree. A part of the tree, he writes, can resemble the whole, as the “tree algorithm” keeps making the same kind of structure repeatedly. As I hike the prairie one afternoon, I look up and all of the sudden it makes sense—once I understand what I’m looking at.

treeoverschulenbergprairieWM2019.jpg

“Growing fractals”  are a type of fractal found in the network of arteries, veins, and capillaries in the vascular system—another “branching” effect, Ball tells me. I think of the “arteries” running across prairie dock leaves, so pronounced in the autumn.

Prairie Dock SPMA2016WM.jpg

I reflect on these concepts and my head aches. Fractals. Symmetry. So fascinating. So…complex. I regret now my ability to dodge everything math-related in college except for a course called “Cardinal Numbers.” A sort of 101 math for art majors. But maybe it’s not too late?

Early one morning, wading Clear Creek at Nachusa Grasslands, I admire the dew drops. I remember reading in Ball’s book that beads of water are driven by surface tension. Simply put, he says, surface tension pulls dew and rain into these “droplet” shapes, and gravity helps flatten the droplets. Ahhh. Look at that. Yes.

CROSBYWM-claritysecondaryphotoWaterdropsClearCreekNG2017 copy.jpg

A different sort of pattern. I search for water droplets: on leaves, spiderwebs, even dragonfly wings. Each dewdrop has heightened meaning.

As I continue reading, chapter after chapter, then go for hikes to explore the different patterns in Ball’s book, his simple explanations for a non-scientist open up a new world for me. A world where math seems a little more applicable. A little more accessible. A little more…meaningful. Perhaps, though, the best moment in Ball’s book  is when he writes that the law of pattern formation is driven by wonder.

GladeMallowSPMA7519WM

“We need to marvel and admire as well as to analyze and calculate,” Ball writes. Oh, yes. I’ve always been attuned to wonder; marveling comes without effort for me. Now, I’m learning the other side of the equation. Such an astonishing world!

So many “patterns” to marvel at and admire in the month of July on the prairie. Why not go see?

Anecdotally, the most beautiful time on the prairie is supposedly the Fourth of July.  I love all four seasons in the tallgrass: the blue and black palette of winter, the golds and rusts of autumn, the first green shoots needling up through the ash of a prescribed burn in spring. But this year, from the white wild indigo and coneflowers, to the prairie lilies…

….to the black-eyed Susans…

…it’s easy to make a case for this as the most lovely season of all.

It’s not only the plants that are striking. Deep in the prairie wetlands, a calligrapher’s fly hangs out in the big bur reeds. The blooms it explores seem a foreshadowing of fireworks later this week.

Soft spiky explosions of foxtail barley grass line the prairie trails. I read up on it, and discover it’s also called squirrel-tail grass. What great names!  I love this silky grass, even though it is a bit on the weedy side. More “fireworks” to enjoy.

The leaves of mountain mint and bee balm, crushed between my fingers, envelope me in their sharp fragrance as I hike.  I chew a few of the leaves, enjoying the taste. While admiring the wildflowers and prairie grasses this summer, I also monitor dragonflies and damseflies—counting the different species and their numbers on the prairies and in the wetlands.

Ethereal damselflies have shown up. New ones I’ve not seen before like the one below. Sweetflag spreadwing? I’m not sure. I pore over my field guides, looking at photos and parsing through identification marks.

This lyre-tipped spreadwing, with its metallic body sizzling in the sunlight, stopped me in my tracks.

Both spreadwings are new to me this summer, after chasing dragonflies for more than a dozen years.  Cascades of wildflowers, a profusion of spreadwing species…perhaps the rainy deluge the past three months has brought these about? It’s nice to think so.

There are many different bluets on the prairie, but this azure bluet damselfly in the prairie savanna grasses is a new discovery for me, and for our site.

Marla Garrison’s wonderful Damselflies of the Chicago Region taught me to look for the “bat” image on the lower part of the azure bluet’s abdomen (most people call it “the tail”). Can you see it? Right above the blue segments.

More familiar dragonflies are also out and about. Eastern amberwing dragonflies, like this female, do handstands to try and cool off in the sweltering heat.

I never tire of the widow skimmer dragonflies, even though they are ubiquitous in my region.

Ebony jewelwings, like this pair (the female with a white dot on her wings) are the essence of summer. They fly loops in and out of the reed canary grass along Willoway Brook, snatching insects and looking for mates.

I’m looking forward to celebrating the Fourth of July with my family this week. But the best fireworks happen all summer long on the prairie. Explosions of wildflowers. The pop of color from a new dragonfly or damselfly. Unusual insects to discover.

So many new adventures to anticipate.

So much to be grateful for.
