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.

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.

Tolkien’s Prairie

Although they weren’t written about a prairie, these hopeful words from J. R. R. Tolkien’s The Fellowship of the Ring,  part of “The Lord of the Rings” epic trilogy, seem especially fitting.
All that is gold does not glitter,
