Frequent viewers of this blog have probably noticed that I am doing a little series of postings featuring common dragonflies that at first glance might look similar. Today’s “star” is a mature male Eastern Pondhawk (Erythemis simplicicollis). Like several other dragonflies in recent postings, the Eastern Pondhawk has a primarily blue body, but several characteristics make it possible to distinguish this species from others.

Both the male and female Eastern Pondhawks have green faces and the male has distinctive white terminal appendages, i.e. those little protrusions at the end of the abdomen (the “tail). Dragonfly specialists spend a lot of time focusing on those appendages, because immature males often have the same coloration as females. In this case, an immature male Eastern Pondhawk would be green with black bands on the abdomen. For the sake of comparison, I am including a photo I took on the same day of a female Eastern Pondhawk. If you compare the tips of the “tails” of the male and the female, you should be able to see the anatomical differences between the genders.

Although it doesn’t help in identifying them, I can’t help but note that Eastern Pondhawks are voracious predators. I think that I have captured more photos of Eastern Pondhawks feeding on other insects that of any other species. When I captured this image last week, I had no idea that the dragonfly was devouring a damselfly. If you click on the image to enlarge it and look just to the left of the dragonfly’s head, you will notice a set of small wings. As you look more closely, you can see the damselfly’s body hanging vertically just below the dragonfly’s head. Yikes!

Although we are well into October, some of my beloved dragonflies are still hanging on at Occoquan Bay National Wildlife Refuge. Here are some dragonfly shots from the past 10 days of (1) a male Blue-faced Meadowhawk (Sympetrum ambiguum); (2) a female Eastern Pondhawk (Erythemis simplicicollis) with a hoverfly in her mouth; and (3) a female Autumn Meadowhawk (Sympetrum vicinum).

I hadn’t really noticed before I aggregated this shots that all three of the dragonflies were perching on leaves. During the summer months, a significant number of the dragonflies that I photograph are perched higher on stalks of vegetation or on branches. In addition to these smaller dragonflies,

I have also recently spotted Common Green Darners, Wandering Gliders, and Black Saddlebags patrolling over the fields. Unfortunately, none of them paused long enough for me to get shots of them. All three of those species are migratory species and they may have been fueling up for a long journey ahead.

Have you ever gotten into a staring contest with a dragonfly? Dragonfly eyes can have an almost hypnotic effect on you when you look directly into them..

I went eye-to-eye with this Eastern Pondhawk dragonfly (Erythemis simplicicollis) on Monday at Occoquan Bay National Wildlife Refuge. She was the one to break eye contact first as she cocked her head, smiled at me, and decided the contest was over.

This image is a little gruesome, but here is a close-up look at an Eastern Pondhawk dragonfly (Erythemis simplicicollis) as it consumed a damselfly that it had captured this past Monday at Occoquan Bay National Wildlife Refuge in Northern Virginia. The second image shows a different Eastern Pondhawk with a different damselfly—the pondhawks seemed to have a particularly voracious appetite that day.

I was simultaneously fascinated and horrified yesterday at Occoquan Bay National Wildlife Refuge as I watched this Eastern Pondhawk dragonfly (Erythemis simplicicollis) gnaw on the head of a colorful Calico Pennant dragonfly (Celithemis elisa) that it had captured. I know that dragonflies eat other insects, but in my mind I tend to think of them consuming mosquitoes and other such smaller insects. Some of them, however, apparently prefer larger prey, including other dragonflies.

I couldn’t help but notice Friday at Occoquan Bay National Wildlife Refuge how closely the green on the body of this Eastern Pondhawk dragonfly (Erythemis simplicicollis) matched the color of the vegetation on which it chose to perch. It won’t be long before pondhawks are all around us, but it was still nice to spot my first one of the season.

I don’t know about you, but if I were an insect with large, fragile wings, I think that I would avoid perching on vegetation with large thorns. This male Eastern Pondhawk dragonfly (Erythemis simplicicollis), however, is obviously bolder and more skilled than I am. With precision flying skills matching the parking abilities of an inner city driver, he has managed to squeeze into a space that seems barely large enough to accommodate him.

Pointless perching—that seems to be the point.
