As I mentioned a few weeks ago, this is the time of year when the focus of my nature explorations turns away from birds and toward dragonflies and other insects. And just like the birds this year, the dragonflies seemed to arrive later than usual, requiring enormous amounts of patience from those of us eagerly awaiting them.
But in the past week or so the dragonfly activity has finally picked up and boy, oh boy, am I having fun! I’ve got so many photos to show you that it’s hard to know where to start. This first post is going to describe an exciting encounter I had today, and then in another post I’ll show a wider variety of species from my dragon-hunting expeditions.
A few days ago a friend told me about a good spot to see a lot of clubtails, a group of odes that I need more experience with. The location is in Oak Openings Preserve, one of our much-loved metroparks. So I headed over there on Thursday and spent about 90 minutes taking photographs of the many clubtails and other species in the meadow and adjacent mowed lawn area.
The weather today was cool and overcast, not the best conditions for odonata to be flying. But I couldn’t resist going out anyway, just to see what I could turn up. My first stop at another nature preserve was discouraging because nothing was flying. At all. I took photos of various fishing spiders on lilypads. I saw a turtle. The sun started peeking out as I was leaving, and I finally found a single Blue Dasher and a single Common Whitetail. That’s when I decided to go back to Oak Openings to check out this meadow again. And boy am I glad I did!
By the time I emerged from the wooded trail into the meadow clearing, the sun was shining brightly and there was a light, cool breeze. It didn’t take long to start finding the clubtails either resting in the grass or flying…up & down and up & down…in their signature roller-coaster flight style. They’re so much fun to watch.
There was lots of cottonwood fluff blowing around, making it look like it was raining cotton balls.
And that’s when it happened.
A dragonfly swooped down in front of me and grabbed what I thought was a clump of cottonwood seeds. Immediately his flight seemed to be more difficult, and he quickly dropped to the ground a few feet away. I’m no fool, and I knew this was going to be good. So I instantly started shooting photos, not even stopping to figure out what he’d nabbed for lunch.
As I shot frame after frame, I quickly determined that he’d nabbed not a clump of cotton, but a large-ish fly-type insect. Now I know that the prey was a Summer Fishfly, aka Chauliodes pectinicornis. I don’t know much about fishflies, but have learned a bit in writing this for you. Their life cycle is similar to that of the dragonfly, interestingly enough. They spend most of their lives as aquatic larvae, then emerge as these winged adult flies. The fishfly adult can live for about a week — if it doesn’t get eaten by another winged insect, as this one did.
Notice the large mothlike antennae on this one — that’s how we know it’s a male. And look at the pretty black-and-white veining in those translucent wings.
As I watched the clubtail begin chewing into its body, the fly thrashed its thorax back and forth in an attempt to escape. At one point it looked like the fishfly was trying to hold on to a blade of grass as the clubtail tore into his abdomen.
I think this dragonfly is an Ashy Clubtail, but I’m not positive about that yet. It’s pretty hard to differentiate a couple of the clubtail species without extreme closeup photos of the reproductive organs on the tip of the abdomen. I’m still examining various photos from this series to try and pin that down, but whatever it turns out to be, isn’t this so cool?!
As I witnessed this predator/prey drama, I was standing alone in this large clearing surrounded by immense trees. When the clubtail finally flew (with much difficulty), taking the remains of its prey up into one of those tall trees, the smile on my face was a mile wide. I think I might even have giggled out loud from sheer joy.
And now I’ll leave you with a calmer image, one of a pretty little Pearl Crescent butterfly feeding on clover…blissfully unaware of what lurks nearby…in the meadow of death. 😉
