During the summer it seems like dragonflies are everywhere, perching prominently in plain sight, but this early in the season there are a whole lot fewer of them and the ones that are around are hard to find. Fellow dragonfly enthusiast and blogger Walter Sanford recently did a posting about some Ashy Clubtail dragonflies (Phanogomphus lividus) that he had spotted at Jackson Miles Abbott Wetlands Refuge.

I had never seen this species before, so I set off this past Friday to see if I could find one of my own. Walter had alerted me to look for the Ashy Clubtails perched in the grass and in the low vegetation that surrounds the small pond at the wildlife refuge. I circled the pond several times in vain before I suddenly caught sight of some dragonfly wings shining in the sunlight. I was able to track the dragonfly during its short flight and saw where it landed in the grass.

Almost certain that I had found an Ashy, I approached the dragonfly slowly and cautiously, fearful of scaring it away before I could get a shot. I was face-to-face with dragonfly, which is not the greatest position for capturing its details, and was able to confirm that it was an Ashy Clubtail. Its pale coloration and very clear wings indicate that it is newly emerged, what is often called a “teneral,” and it looks to be a female. Having gotten a few shots, I tried to get a better angle and spooked the dragonfly.

Buoyed by my success, I was motivated to search even harder and eventually spotted two more teneral female Ashy Clubtails. One was in some chest-high thorny bushes and I had to push up against them to get as parallel as possible with its body for a detailed shot. I was able to photograph the third Ashy from almost directly overhead and the final photo gives you the best overall view of this beautiful dragonfly.

These Ashy Clubtails ares not as brightly colored as some of the dragonflies that will appear later in the summer, but they were definitely a welcome sight for me.

As I was searching for dragonflies yesterday at Jackson Miles Abbott Wetland Refuge, I noticed an unusually large bumblebee and started to give chase. When it landed and I moved in close, it became clear that it was not a bumblebee after all—it was a clearwing moth.

I have seen clearwing moths in the past of the the variety commonly known as Hummingbird Clearwing Moths (Hermaris thysbe), but they have generally been hovering like a hummingbird rather than perching like this one and their wings were outlined in red, not black. It took only a few minutes of internet research to discover that this is a Snowberry Clearwing Moth (Hemaris diffinis).

This delicate little butterfly was facing away from me, but I love the way that you can see the beautiful markings on the inside of its wings. I believe it is an Eastern-tailed Blue butterfly (Cupido comyntas), a kind of hairstreak butterfly with an average wingspan of only about one inch (25mm).

I chased after a number of these butterflies earlier this week when I was exploring Jackson Miles Abbott Wetland Refuge at Fort Belvoir, Virginia. They don’t fly very fast, but their flight path is unpredictable and close to the ground and they usually don’t perch for long in one spot.

I suspect that if someone had been observing me from a distance, they would have been hard-pressed to figure out what I was trying to photograph and might have concluded that I was merely another crazy wildlife photographer. We are a peculiar breed, aren’t we?

Now that the dragonfly season has started in my area, I am devoting more and more of my available photography time to searching for these beautiful little creatures. Some dragonflies can be found almost anywhere, but many of them require a very specific kind of habitat and may be present for only limited periods of time.

Yesterday afternoon I visited Jackson Miles Abbott Wetland Refuge, which features a small pond surrounded by a pathway. Last year I found several different dragonfly species there, so I knew that I might have a chance of seeing some dragonflies. I looked in the brush and in the vegetation and came up empty-handed until I looked at the water and spotted several dragonflies flying low above the water.

I recognized the dragonflies as Common Baskettail dragonflies (Epitheca cynosura) and knew that I faced a challenge—this species seems to fly continuously and rarely have I seen one perch. I realized that if I wanted to get some shots of the dragonflies I would have to capture the images while they were flying.

I had my Tamron 180mm macro lens on my camera and started to track the flying dragonflies. I have tried a number of focusing techniques in the past and have had the most success when I focus the lens manually (although I hesitate to use the word “success,” given the high rate of failure in getting an in-focus shot). This was my favorite shot of a Common Baskettail flying above the water. There is a bit of motion blur in the wings and I had to crop the image quite a bit, but I managed to keep most of the dragonfly in focus.

I walked multiple circuits around the pond, still searching for more dragonflies. I tend to like to keep moving, rather than sticking in one spot. As I reached one end of the pond, I suddenly realized that a dragonfly was hovering in mid-air right in front of me. The dragonfly was moving slowly above a grassy patch adjacent to the pond, but did not seem interested in heading for the water.

I could hardly believe my good fortune and tried to compose myself and focus on the dragonfly. I managed to get some detailed shots that show, for example, how the Common Baskettail folds up its legs when flying. I took the first shot below while on my knees, so that I was almost level with the dragonfly. For the second shot, I was shooting down on the dragonfly and it looks almost like it was taken by a drone, hovering above the hovering dragonfly.

On the same day that I saw the Common Whitetail dragonfly that I featured yesterday in my blog posting, I was thrilled to have the chance to photograph an uncommon dragonfly, a male Stream Cruiser (Didymops transversa). I had never before seen a Stream Cruiser, but local dragonfly expert and fellow photographer Walter Sanford had observed them in the past at Accotink Bay Wildlife Refuge and offered to guide me.

It’s somewhat of an understatement to say that Stream Cruisers are hard to spot. The are not very big (about 2.2 inches (56-60mm) in length), they are skittish, and they often perch on the stems of low vegetation. During the hours that we searched for them, I observed a couple of probable Stream Cruisers in the air, but lost them in the blur of the vegetation and never saw a single one land. Walter saw the first one of the day, a female, and posted an awesome photograph of the beautiful dragonfly in a blog posting yesterday. Unfortunately for me, I was unable to make it to the dragonfly’s location before she flew away. Walter spotted a few more Stream Cruisers during the day, but each time I couldn’t get there quickly enough to see one.

I was beginning to think that I was going to end up empty-handed for the day when Walter called out that he had spotted a male perched in the underbrush. This Stream Cruiser was cooperative enough to stay perched as I rushed to try to get a shot. I had my Tamron 180mm macro lens on my camera at that moment. The dragonfly and the stem on which it was perched were so small in the viewfinder that my camera’s autofocus would not lock on my subject, so I had to resort to focusing manually. Dragonflies have so many fine details that it is really hard to tell when they are in focus. This image was the best I could get after cropping the initial shot quite a bit.

I decided to push my luck and see if I could get a better shot with my Tamron 150-600mm lens that I use primarily to photograph birds. Amazingly the dragonfly stayed put while I changed lenses. Once again I had to focus manually, which is an even bigger problem with this lens, because the focus ring is located really close to the lens mount. It’s hard to hold the camera steady and focus manually at the same time.

Here’s an image that I shot at 600mm. I managed to get the eye pretty sharp and to capture some of the details of the dragonfly’s incredibly long legs, but the depth of field was so shallow that the abdomen is out of focus. Normally I will try to move around the subject to be as parallel as I can be, but in this case I stayed fixed at one spot and remained as immobile as I could.

It is really nice to start off this dragonfly season with a new species. If you want to learn more about the Stream Cruiser dragonfly, check out this page from the Dragonflies of Northern Virginia website (and stay tuned for Walter’s shots of this dragonfly that should appear tomorrow morning in his blog).

Thanks to recent warmer weather, dragonflies are finally starting to emerge in Northern Virginia. I captured this image of a female Common Whitetail dragonfly (Plathemis lydia) on Monday at Accotink Bay Wildlife Refuge. Unlike many species with the word “common” in their names, Common Whitetail dragonflies are actually pretty common. They are among the first species to emerge in the spring and among the last to depart in the fall. Unlike many of the early spring species, they are habitat generalists—you can find them pretty much anywhere  and do not have the scour the underbrush or walk through streams in remote locations.

Although I spotted a Common Green Darner dragonfly earlier this month, I was not able to get a photo of it and suspect that it had migrated from another location. This is my first photo of the season of a “native” dragonfly, with plenty more sure to follow in the coming months.

Normally I see turtles at water level, but this intrepid turtle had climbed up the trunk of an overhanging tree at Jackson Miles Abbott Wetlands Refuge on Monday and was perched several feet about the surface of the pond. I love the way that his coloration and texture almost perfectly match those of the tree.

A short while later I encountered three turtles perched on the trunk of a tree growing at an angle out of the water. The angle was steep enough that I was not sure how they managed to get themselves into position or how they were able to keep from sliding down into the water.
