Here in northern Ohio we’ve entered a period of the year that I think of as, “Is It Time Yet?” We’ve been through the depths of a frigid winter and have been treated to some brief warmups in which all the snow melted and we could bask in the rejuvenating glow of the sun. Those late winter warm spells are the first sign we get that spring is, if not around the corner, at least on the horizon.
I always start dreaming of the not-too-far-off day in April when I’ll see my first dragonfly of the year, a day of virtual high-fives texted between my odeing buddy and myself: Me: “I saw my first Green Darner today! What did you find?” Him: “I think I saw a Springtime Darner!” Me: “Woohoo, it’s on!” (And that’s our virtual high-five.)
And so ode season will kick off and we’ll spend the summer happily sharing cool sightings and photographs. Until that day comes, I must have patience. But I can still daydream. The other day I went to a spot at Maumee Bay State Park where I photographed this flag-tailed spinyleg last July.
Isn’t he spectacular?! I have such great memories of stalking him around the edges of that pond, and the excitement that bubbled up in me when he came to rest on a log very close to the water’s edge, in easy photographic range.
This is the photo I took of that pond a couple days ago:
Standing there at the edge of the frozen water, I felt like a small child waiting outside a toy store, asking her mom, “Is it open yet? Huh, mom? When will it open?!” Because I know that there are larvae of dragonflies and damselflies beneath that frozen water right now, just waiting for the temperatures to rise.
Some species of dragonflies migrate to warmer climates (more about that below), but most of the adults die before winter each year. If they’ve been successful in breeding, they’ve left behind larvae who will live under water for varying amounts of time, depending on species. Some of them live under water for years. And each spring, some generations will be ready to emerge from the water and shed their exuviae to become the beautiful winged adults that are the source of so much of my summertime entertainment.
If you pay attention around any fresh water source, you can often find many of these empty exoskeletons, or exuviae, attached to vegetation. There’s always a hole on the top where the adult dragonfly broke through and emerged into a whole new world. That’s just one more aspect of their lives that I find so fascinating; they live part of their lives under water and then another part as incredible speeding winged insects who can maneuver like helicopters.
Here’s another exuvia I found last summer. I can’t tell which species this one was, because I should have taken a photo from the side as well as from the top. I’m just learning to identify the exuviae, using tools like this one from the National Park Service.
I mentioned that some species of dragonflies migrate to warmer climates. A study was published late last year that indicates that the common green darner (Anax junius) has a migration very similar to that of the monarch butterfly. Their migration involves three separate generations of adult insects, moving north and south at various times. This article describes the study and has some neat diagrams to illustrate it. (Oh, I should mention that if you have any interest in contributing your sightings in this last year of the Ohio Dragonfly Survey, you can click here for details.)
According to that article, there are some common green darners emerging from waters in the southern parts of North America right now, and they’ll soon be on their way to Ohio where my camera and I will be waiting impatiently for their arrival. I think I can make it. In the meantime, I’ve got a very exciting mystery trip coming up in less than two weeks, so that will provide a much-needed distraction as I await the return of the odonata to Ohio. I can’t wait to share this trip with you!
