Tallgrass Prairie Dragons

“One dragonfly—even the most silent of ponds comes alive.”—Scott King

******

They’re here. All around us. In the prairie wetlands. Scattered in the tallgrass ponds.

Dragons.

Dragonflies, that is. When the sun shines on cold days. While the ice is deep on the prairie ponds.

“What?” you might say. “Cindy, there aren’t any dragonflies flying through the snow.” Truth. And yet…under the water’s surface, rumbling across the substrate of silty river bottoms, dragonfly nymphs are going about their business. They look a bit different in their larval stage, don’t they?

These tiny nymphs eat. Grow. Molt. Eat some more. Repeat. Repeat. Repeat. Until that magical day when nature tells each species GO!

They emerge, exchanging a life in the water for a short life in the air.

Their lives will flare into color, channeling sunlight. And then, all too soon, their time is up. It might end with the snap of a bird bill. The splash of a fish, as it snatches the dragonfly in motion. Or a bullfrog, tonguing the dragonfly out of its flightpath.

Now you see it.

Now you don’t.

Or, if a dragonfly is lucky, it will live a few weeks before dying its natural death.

A life so short! Shouldn’t we admire them while we can?

And then, there are the migratory dragonflies. Big, bright, and ready to return to the Midwest this spring.

Not all dragonflies migrate. But the ones that do—common green darners, wandering gliders, black saddlebags, and other migratory species—left in the autumn en masse, bound for warmer climes. The Gulf of Mexico, perhaps, or even Central America. And now, their progeny return singly. We’ll see them as early as March in Illinois, ready to complete the remarkable cycle.

The wandering glider, found on every continent but Antarctica, is known to travel more than 8,000 miles!

Dragonflies don’t have the excellent press agents that monarch butterflies do, so it’s up to citizen scientists, researchers, and organizations such as The Xerces Society to collect data and learn more about these far-ranging insects.

For most of us, it’s enough to know dragonflies will soon be back in the Midwest to brighten our gardens and enliven our world. Returning migrants and also, the nymphs living in the water here, will appear. They’ll zip around stoplights, catch bugs at ballparks, and pose on wildflowers.

Such pizzazz.

Though snow still flies in the Chicago region, my dragonfly “EDS”—early detection system—is on high alert. What species will I see first? When will I spot it? Where?

From that moment on, my days will see constant attention on the skies and wetlands. I can’t wait.

Let the dragonfly chasing season begin!

The opening quote is from Scott King (1965-2021) in his book with Ken Tennessen and Kobayashi Issa, Dragonfly Haiku (Red Dragonfly Press, 2016). King, an engineer who grew up in northern Minnesota, was also a naturalist who wrote several books about insects. He was the founder of Red Dragonfly Press, which relied on vintage typesetting and printing equipment, and he hand-bound the poetry chapbooks he published with needle and thread. In a tribute to Scott in the Minnesota Star Tribune, he was lauded by one friend as “that rare combination of technical genius and poetic soul.” Said another friend, “He was constantly drawing your attention to what is around you that you might not be seeing or noticing.”

Requiem for Bell Bowl Prairie

On March 9, 2023, despite public opposition, one of Illinois last prairie remnants was bulldozed by the Chicago-Rockford International Airport. Once a prairie remnant is lost, we are unable to replicate it. Let this travesty be a wake-up call for all of us who love and care for tallgrass prairies anywhere. Wherever you hike, volunteer, or see a prairie, ask yourself—is this prairie legally protected? If not, advocate for its protection now. Let this be the last prairie remnant we lose in what we’re so proud to call “The Prairie State.”

Waiting for Prairie Dragonflies

“Wild beauty sustains us…it makes each of us an heir to wonder.” — Terry Tempest Williams

*****

Crocus bloom in my backyard, bright spots in the brittle little bluestem and prairie dropseed.

When I see these flower faces turned toward the sun, I know it won’t be long until the dragonflies arrive on the prairie. I check Willoway Brook. Then, the local ponds. A prairie stream.

Under the water’s surface, the dragonfly and damselfly nymphs are waiting.

Soon, they’ll emerge…

…then transform from creatures of the water to their teneral stage. Weak, colorless, they are at the mercy of birds, frogs, and predators with an urge for a “dragonfly crunch” lunch.

They slowly transform……

…to aerial experts with brilliant coloration.

Those eyes!

The diversity of Odonates never ceases to startle…

…delight…

…and amaze.

The spreadwing damselflies like this one below (so difficult to ID)….

…remind us there is mystery in the midst of knowledge. Not everything can be known at a glance. Then, later, the white-faced meadowhawk dragonflies show up, their pearl faces lending confidence to their name and ID.

Some early emergents seem to scoff at April snows and colder weather. We may even see green darners working the ponds for early insects by the end of March. Weather permitting. Down south, the migratory dragonflies will begin making their way to the Midwest. They’ll arrive soon—at the end of the month or early in April—the green darners, the wandering gliders, the black saddlebags…

…ready to find a mate.

Together…

…they give us hope for a healthy and prolific Odonate future.

Soon, the prairie will come alive with the whiz and zip of dragonflies and damselflies. Meanwhile, we watch. Anticipating.

Will you be there to see them return and emerge? Walk the prairie paths. Be alert.

Eyes to the skies.

I can’t wait.

Under the Prairie Ice

“To keep every cog and wheel is the first precaution of intelligent tinkering.”–Aldo Leopold

*****

Polar Vortex! In the Illinois prairie region, all the chatter is about the week’s forecast: wind chill temperatures of 50-plus degrees below zero. Brrr! It’s a good time to dream a little bit about the summer to come.

One of my favorite tasks as a prairie steward is monitoring dragonflies.  People often ask me in the winter, Where are the dragonflies now? How do they survive the brutal cold? 

Some, I tell them, like the green darners and black saddlebags, have migrated south to reproduce. Later generations journey back north again, much like the well-publicized monarch butterfly. But most of our dragonflies are still here—in the nymph stage—under the surfaces of streams, ponds, and pools of prairie wetlands, waiting for spring and warmer temperatures. Under the prairie ice.

Dragonflies and their population changes tell us a lot about our water quality. Dragonfly responses to climate also help us understand what we see happening in the see-sawing temperatures and weather changes in the world around us. Good reasons to care! With this in mind, citizen scientists monitor dragonflies of all species, tracking their numbers each year.

We need our dragonflies. I’ve spent a lot of time kayaking and looking for dragonflies and damselflies on Silver Lake at Blackwell Forest Preserve in Warrenville, Illinois, just for fun.  But now, in this January cold, the lake is full of ice fisherman.

Just across the preserve, not far from the ice fishing houses, is my destination—the Urban Stream Research Center. Here, one of our most vulnerable insect species, the Hine’s emerald dragonfly, is being reared.

Some people dream of meeting sports heroes. Others, their favorite rock star. Me, I dream of seeing the Hine’s emerald dragonfly (Somatochlora hineana) winging its way through a prairie preserve. It’s our only federally-endangered dragonfly. Finicky? Yes! It has a lot of special requirements, including shallow flowing water and time spent in burrows made by the devil crayfish. 

During the winter months, I pore over my favorite dragonfly field guide by Kurt Mead,  part of the North Woods Naturalist Series…

… and open it to the Hine’s emerald dragonfly spread. Then, I think what it would be like to see the real thing.

Today, I’ll get part of my wish.

Heading up the project in its third year in the Chicago Region is DuPage County Forest Ecologist Andrés Ortega. His enthusiasm for dragonflies and passion for the project are evident from the first moment of my arrival at the center.

Andrés reaches into a refrigerator, and pulls out a dozen vials of tiny Hine’s emerald dragonfly nymphs.

The dragonfly nymphs are in “diapause,” just as nymphs are outdoors. These nymphs enjoy cool refrigerator temps of about 40 degrees Fahrenheit;  their normal overwintering temperature, Ortega tells me.

The eggs were gathered from gravid female dragonflies at known breeding sites in DuPage and Cook Counties, Andrés tells me.  Once netted, the tip of the female dragonfly’s abdomen is dipped into water—a process that simulates ovipositing—causing her to release her eggs. After the eggs are harvested, they are taken to a research laboratory in South Dakota. Here, they hatch and are cared for through their first months or even years of nymph life.

Then, they are driven to Illinois and hand-delivered to Ortega at the Urban Stream Research Center.

These are ferocious little critters. Andrés tells me they keep similar-sized nymphs with other similar-sized nymphs, as larger ones will enjoy the smaller ones for dinner if thrown together. Cannibalism! It’s a bug-eat-bug world out there. Staff carefully control the water quality (which should not be too clean) and water temperature.

In the spring, the nymphs will be released into the research center’s indoor raceways. These are long pools that mimic stream-like conditions. The temperature of the water in the raceways is carefully calibrated to reflect the rising temperatures outdoors.

Raceways are custom made by employees expressly for the dragonfly rearing. Sand, rocks, frayed rope pieces, and plastic aquarium plants offer hiding places for the nymphs. In about mid-May, the nymphs will begin feeding from a menu that includes small crustaceans and midge larvae. The screens and netting will keep midges from escaping and interfering with other research work at the center, such as mussel propagation.

It will take the dragonfly nymphs about four to five years to reach maturity, from the egg stage to the beautiful creatures of the air I see in my field guide. When ready to emerge, they will be released into suitable nature preserves in the state.

Ortega tells me that less than one percent of the Hine’s emerald dragonfly nymphs survive in the wild. Pretty slim odds, aren’t they?  I’m grateful to people like Andrés Ortega. He is one of our unsung heroes, doing the hard work of keeping part of the natural world from vanishing forever.

The next time you see a frozen prairie stream or pond this winter, think of the many different species of dragonflies waiting to emerge, just underneath the surface. Who knows? This might be the year we see more of the Hine’s emerald dragonflies, cruising through prairie wetlands. I’m planning to show up and look.

How about you?

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.

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.

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.

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.

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.

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?

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.

Calico pennant.

Springwater dancer.

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.
