Sometimes you’re the windshield, sometimes you’re the bug.

Mark Knopfler, The Bug Song

Dragonfly season is fast coming to a close, and this is always a melancholy time of year for me. I get so much pleasure from going out to watch them (and other insects) and it’s hard to let go of that every fall. But then again, if they were here all year long I might not appreciate them as much. It helps if I think about it in the way I think about rainbows: we’d take them for granted if they were permanent fixtures in the sky, but we value them because they’re so brief and infrequent.

This summer has been sort of miserable — either raining endlessly or so hot I could barely tolerate it. And the mosquitoes were ravenous! I spent much less time in the field this summer, and I sure hope I’ll be back to my normal level of nature explorations next year. But the other day we got one of our first beautiful fall days, with a crystal blue October sky (in September!) and refreshingly cool north winds. It’s been wonderful to turn the air conditioner off and open all the windows in the house to get some fresh air in here.

So on this gorgeous day I took advantage of the comfortable temperatures to get out for one of my last dragonfly surveys of the season. As I started out I was feeling sort of dejected because there was hardly anything flying, dragonfly or otherwise. My spirits lifted a bit when I saw a tiny gnat ogre, our smallest robber fly at about 1/4″ long. There are three possible Holcocephala species in Ohio, and they’re not easy to identify. But they’re one of my favorites and I’ve seen lots of them at Wiregrass Lake this year, although they’ve gotten scarce in the past few weeks. I took some quick photos of the tiny predator on his hunting perch and moved on to resume my dragonfly count.

A few minutes later I was taking photos of a female spreadwing damselfly, and getting much happier because spreadwings are rare at this location, and this was the first one I’d seen here all summer. This is most likely a Slender Spreadwing (Lestes rectangularis).

Spreadwings are so-named because of the way they hold their wings outspread, in contrast to other damselflies, who hold their wings folded together. I think they look like they’re wearing ballerina tutus, and that makes me smile.

My spirits soared yet again when the damselfly grabbed a gnat ogre right in front of me! It happened so fast that I didn’t realize what she’d caught until I enlarged the pics on the back of my camera. A case of predator becoming prey, or as Mark Knopfler put it, “Sometimes you’re the windshield, sometimes you’re the bug!”

I sat on the ground and watched her for ten minutes as she enjoyed her meal. She started with the head, then ate the thorax, dropping the wings on the ground. Here’s a short video so you can see some of the action. There’s some wind noise but you might be able to hear crunching sounds as she munches on her lunch. (I don’t think the video needs a “gross” warning, and if you haven’t clicked away already, you’ll be fine!)

I hope you enjoyed that as much as I did. Predatory insects are fascinating because you just never know what you might get to see. And in this case, when one predator catches another one, it’s very dramatic. (If you want to see a series of dramatic photos I took of another insect interaction, check out “The Circle of Life, Insect Edition.)

As I left the damselfly to finish her meal, I snapped a photo of the scene. The circle indicates where she was, in the vegetation alongside Wiregrass Lake. If you weren’t tuned in to these insects, you could easily walk past them and not have a clue about the life-and-death drama that was playing out at your feet!

That’s one of the things I love about being out there paying close attention to insects. It’s like I’m living in a fascinating secret world that nobody else is noticing. And yet I know there’s still so much out there that I’m missing, and that’s what keeps me going out again and again.
