August’s Prairie Marvels

Note to readers: This week’s Tuesdays in the Tallgrass is a special Sunday edition! I’ll be back to publishing on Tuesdays and our regular schedule next week. Thanks, as always, for reading.

“The starting point must be to marvel at all things, even the most commonplace.” — Carl Linnaeus

*****

When the impatiens open their conical orange and yellow freckled flowers to the delight of the ruby-throated hummingbirds and long-tongued bees, I know that summer is slipping toward autumn.

Impatiens8519SPMAWM.jpg

Look at enough impatiens’ blooms, and you’ll discover the holes chewed by bumblebees in search of nectar. You can imagine their thoughts: Why work so hard when there are shortcuts to be had?

It seems like an August kind of mentality; slow moving days, high humidity, blue skies and sunshine interspersed with some welcome rain. Listening to the zithering of the cicadas; watching fireflies from the back porch. So much to marvel over.

The ruby-throated hummingbirds work the cardinal flowers in my backyard, blurred streaks moving from scarlet to scarlet. Each year, I worry that I’ve lost the cardinal flowers, then splash! There they are popping up around the pond; scattered through my prairie patch.

Goldfinches work the cup plants for water and early seeds as monarch butterflies swarm the Joe Pye weed blooms that tower over my head.

The black swallowtails love the wild bergamot, as do the bumblebees and sphinx moths. This swallowtail below lost a bit of wing—to a bird, perhaps, or other predator—but still nimbly eludes me when I try to follow it deeper into the tallgrass.

Hiking the Belmont Prairie this week in Downer’s Grove, IL, I saw the first large groups of dragonflies massing —- for migration? It seems early.  I’m unsure. Last year’s swarms came at the end of August. Almost all of the 80 or so individuals I count are green darner dragonflies; with a few golden wandering gliders mixed in. If you blow up this photo on your computer or phone, you’ll see at least 32 individuals silhouetted against the sky.

On the Schulenberg Prairie in Lisle, IL; the first New England aster opened this week like a purple omen, noting the seasonal transition in process. They always say “autumn” to me.

More late summer notes are struck in the ripening of seeds of the spring wildflowers, like prairie parsley (below). As August slides toward its inevitable conclusion, more blooms will be replaced by seeds, gradually tipping the balance from flowers to future progeny.

Tiny calico pennant dragonflies, less than the length of my pinky finger, chase the breezes, then alight for a moment on the grasses.

calicopennantmaleSPMA8319WM.jpg

They’re often mirrored by a Halloween pennant or two close by, forging  an uneasy truce for territories.

Halloweenpennant8319WM.jpg

Each time I see these two species I wonder if it will be the last time, as their numbers taper off this month. In a week or two, they’ll only be memories.

The goldenrod opens, offering its sweet nectar to greedy insects.

The prairie oils the gears of transition. The compass plants point the way.

compassplants8319WM.jpg

These inevitable transitions on the prairie remind me that change, even when not particularly welcome, shakes things up. Jolts us out of our complacency. Reminds us to marvel at what’s happening right now.

bonesetatBelmontPrairie81019WM.jpg

I’ve tried not to take the prairie for granted this summer season.  Each day, each week, I marveled at the joys each particular day offered. But June and July went by too fast and now August seems to be half over. There’s melancholy in the lowering slant of sunshine; the tallgrass elbowing the wildflowers out of the way, the first gold leaf-coins dropping from the trees on the prairie’s edge.

A potent reminder to enjoy the marvels of every summer day on the prairie that we have left.

Let’s go!

The Dragonfly Chasers

If you are old and you wish to be young again, if only for a moment, try and identify a dragonfly. — Simon Barnes

***

In the prairie ponds, streams, and wetlands, they wait. Dragonfly nymphs are about to emerge.

Last summer, I watched the scene below from my kayak. Female dragonflies lay eggs in water or vegetation. The male pondhawk dragonfly (powdery blue) “hover guards” the female (green) so no other males disturb her. Tapping her abdomen into the water, the female ensures another generation of dragonflies, as the male protects her from above. It all happens fast. So fast.

The eggs may hatch in a matter of weeks. In their nymph or larval stage, dragonflies (looking like ferocious beetles) cruise the water, sometimes for years. Then, one morning, these denizens of the deep scramble up a blade of grass and commence the difficult work of change. “Teneral” is the scientific term for the transformation stage. Each dragonfly nymph sheds its ugly husk, and exchanges it for a beautiful winged body.

No longer a water-breather. The dragonfly is now a creature of the air. She takes flight.

Dragonflies dazzle us with their agile antics as they fly; stun us into silent admiration as they bask in sunlight.

This April, I’ll join citizen scientists at Nachusa Grasslands and other prairies in hiking the tallgrass, looking for dragonflies and their close kin, damselflies.

Wandering Glider -SP72316.jpg

A “citizen scientist” is an amateur who contributes information to a scientific body of knowledge. My academic background is in art, journalism, and natural resource interpretation. I have no background in the hard sciences, or specifically, entomology (the study of insects). Yet, the fieldwork I and others do helps build our collective scientific knowledge of  the dragonfly world.

SPMA-halloweenpennant62516.jpg

Dragonfly monitors hike routes through the prairie and pencil hash marks on species lists, ticking off each dragonfly we discover. Green darner? Check. Halloween pennant? Check. Oohhhh… Jade clubtail! Check.

IMG_8247 2.JPG

As I monitor dragonflies,  I pay attention to anything that lifts off from the tallgrass at my approach. Is it a dragonfly? I watch closely.

carolinasaddlebags-sp2014.JPG

Yes! I log it on my list. Bonus: I observe other critters–such as bees and butterflies– as I walk. I note their presence in my journal, and alert site managers if I see something unusual.

monarch 2014.jpg

How does observing dragonflies and damselflies benefit us? The violet skimmer damselfly (below) and other species are complex and colorful. But besides the aesthetics, why should we care?

BLOGviolet dancer SP2015 copy.jpg

Here’s why. Because dragonflies spend the biggest part of their lives in the water, the changes in health and populations of dragonflies and damselflies tell us a lot about how the quality of water changes over time. Clean water is essential to life and our well-being. Clean water is also a non-negotiable resource for future generations.

And so, this summer, you’ll find me in the tallgrass, wandering along shorelines, or deep in a prairie stream, chasing dragonflies. Netting some for a closer look; photographing others. Carefully checking for identifying field marks.

Sure, it’s citizen science. But it’s art as well. Those colors! Those wing patterns! Their names are poetry. Ebony jewelwing.

Their names help form the vocabulary of the prairie community.

If you love the natural world as I do, dragonfly monitoring is one enjoyable and simple way to make a small contribution to keeping it in good shape. Wherever you live, the dragonflies are waiting for you to notice them. Learn a few of their names. Make time to sit and watch them.

It will be time well spent.

Simon Barnes (1951-), whose quote opens this blogpost, is a British sportswriter and wildlife columnist. Once employed by the London Times, he was fired from the newspaper after more than 30 years, supposedly for angering hunters with his remarks in an opinion column about saving an endangered bird. His 16 books include Birdwatching with Your Eyes Closed and How to Be a Bad Birdwatcher.

Leaving Home

“Migration is a blind leap of faith… .” Scott Weidensaul

*****

September.

In a prairie pond, a turtle and a few ducks snooze in the late afternoon sun.

A baby snapper ventures slowly out to explore the rocks.

The last great blue lobelia flowers open and bloom amid the goldenrod. September’s colors.

Deep in the tallgrass, a grasshopper takes a hopping hiatus from the heat.

ng-grasshopper-916

A cool breeze stirs. The tree leaves begin to rustle, then rattle. A sound like waves rushing to shore sweeps through the prairie. It ripples in the wind. Tall coreopsis sways.

glen-ellyn-library-prairie-916

The prairie whispers, Go.

The black saddlebags dragonfly feels restless, deep down in its DNA. Orienting south, it joins the green darners, variegated meadowhawks, and wandering gliders to swarm the skies. Go. Go.

blsaddletwo-jamespate815

The meadowhawk dragonfly hears, but doesn’t respond. It will be left behind. Only a few species of dragonflies answer the migration call. Why?

We don’t know. It’s a mystery.

A flash of orange and black, and a monarch nectars at the zinnias that grow by my prairie patch.  Mexico seems a long way off for something so small. But this butterfly was born with a passport that includes a complimentary GPS system. This particular monarch will go. Just one more sip.

monarch-backyard-ge-916

A viceroy butterfly delicately tastes nectar from goldenrod. No epic trip for this look-alike. Although its days are numbered, the butterfly bursts with energy, zipping from prairie wildflower to wildflower. Go? I wish!

viceroy-91216

A turkey vulture lazily soars through the air, headed south.  These Chicago buzzards won’t drift far. Once they hit the sweet tea and BBQ states, they’ll stay put until spring.

turkey-vulture-ng-916

Go? The red-tailed hawk catches the whispered imperative. She stops her wheeling over the prairie for a moment and rests on top of a flagpole, disgruntled. Go? NO! So many birds heading for warmer climes! She ignores the command. She’ll winter here,  in the frigid Chicago temperatures. Wimps, she says, disdaining the pretty warblers, flocking south.

red-tailed-hawk-tma-916

Meanwhile, the last blast of hummingbirds dive-bomb my feeders, slugging it out for fuel. Think of the lines at the pump during the oil embargo crisis of the 1970s –that’s the scene. Destination? Central America. You can feel their desperation as they drink deeply, then buzz away.

hummingbird-backyard-ge-916

Saying goodbye is always the most difficult for those left behind. Seeing those we know and care about leave home is bittersweet, fraught with loss.

sneezeweed-ng-916

But, as the prairie brings one chapter to a close–with all of its colorful and lively characters…

sunset-cod-91216

…another chapter is about to begin.

Meanwhile, we watch them go. Bon voyage. Safe travels.
