Sharing a perch

Posted in Dragonflies, dragonfly, Insects, Nature, Photography, Summer, wildlife, tagged , , , , , , , , , on September 3, 2022| 10 Comments »

This looks like such a tranquil scene, with two dragonflies of different species sharing a prime perch on a branch overhanging the pond at Jackson Miles Abbott Wetland Refuge, a moment of peaceful coexistence. However, I had been watching these two dragonflies for an extended period of time and knew that the moment of sharing was the exception rather than the rule.

The male Slaty Skimmer dragonfly (Libellula incesta) on the left and the male Swift Setwing (Dythemis velox) had been repeatedly challenging each other for sole possession of the perch. Whenever one of them would perch on the end of the branch, the other dragonfly would fly straight at the one that was perched, attempting either to dislodge the interloper or at least convince him to fly away.  They went back and forth like this for quite a while, alternating possession, though I think the Slaty Skimmer, the larger of the two, held onto the branch for a longer period of time than the Swift Setwing.

I tried to capture them “buzzing” each other, but timing was really tricky and it was almost impossible to keep them both in focus. The second image below is my best effort in showing their interaction. I was low to the ground when I took the shot and really like the perspective with the sky in the background. If you look closely at the lower left corner of the second photo, you may notice that a long-jawed spider was also sharing the perch with the two dragonflies.

Swift Setwing dragonfly in August

Posted in Dragonflies, dragonfly, Insects, Nature, Photography, Summer, wildlife, tagged , , , , , , on August 26, 2022| 5 Comments »

I was delighted on Wednesday to spot this male Swift Setwing dragonfly (Dythemis velox) during a short visit to Jackson Miles Abbott Wetland Refuge. These little dragonflies perch in a distinctive pose with their wings pulled forward, which looked to some scientist like the “ready-set-go” position of a sprinter and is reportedly the reason for the name of the species.

This species is really special to me, because this primarily southern species had never before have been documented in Fairfax County, Virginia, the county where I live, until I spotted one six years ago at this same location. By now there seems to be an established breeding population, and I look forward to seeing them each summer.

As August draws to a close, I am acutely aware that each sighting of a dragonfly could be the last one of the season for that species, so I really savor each encounter. There is beauty all around us, but somehow I have a particular affinity for dragonflies and damselflies—I am endlessly fascinated by these colorful little aerial acrobats.

Swift Setwing

Posted in Dragonflies, dragonfly, Insects, Nature, Photography, Summer, wildlife, tagged , , , , , , on July 3, 2022| 4 Comments »

Each summer season I look forward to photographing Swift Setwing dragonflies (Dythemis velox) at Jackson Miles Abbott Wetland Refuge. These little dragonflies perch in a distinctive pose with their wings pulled forward, which looked to some scientist like the “ready-set-go” position of a sprinter and is reportedly the reason for the name of the species. One of my fellow photographers recently posted some photos of the species in Facebook, prompting me to set out last Wednesday to see if I could find some of them myself.

Six years ago I spotted my first Swift Setwing dragonfly at this same location. This primarily southern species had never before have been documented in Fairfax County, Virginia, the county where I live, so it is kind of special for me to see them each year. (You can see details of that first sighting in my 25 June 2016 posting Swift Setwing dragonfly.)

Members of this species like to perch at the very tip of vegetation overhanging the water and almost always face the water. It can therefore be quite a challenge to get profile shots and almost impossible to get the kind of head-on shots that I love to take.

I had a number of encounters with Swift Setwings and tried a variety of compositions to capture images of these cool little dragonflies. My favorite shot is probably the first one—I really like the way that the colors of the dragonfly’s head are mirrored in the colors of the berries in the background.

Lurking danger

Posted in Arachnids, Dragonflies, dragonfly, Insects, Nature, Photography, spiders, Summer, wildlife, tagged , , , , , , , , , on August 25, 2021| 14 Comments »

I was focused so intently on getting a shot of this male Swift Setwing dragonfly (Dythemis velox) on Monday at Jackson Miles Abbott Wetland Refuge that I did notice that he was not alone on the small branch overhanging the waters of the small pond.

When I first pulled up the image on my computer,  I immediately noticed the strands of spider silk that looked like the guy line of a tent pole. It was only when I started to examine the branch closely, however, that I spotted the elongated shape of a Long-jawed Orb Weaver spider (family Tetragnathidae) perched below the dragonfly on the same branch.

The dragonfly was skittish and flew away when I got too close. I suspect that he was unaware of the fact that I was not the most immediate threat that he faced—danger was lurking from below on that branch that my experience had shown was a favorite perch for Swift Setwings.

Swift Setwing in August

Posted in Dragonflies, dragonfly, Insects, Nature, Photography, Summer, wildlife, tagged , , , , , , on August 14, 2021| 2 Comments »

As we move deeper into summer, some species are starting to disappear. I keep a mental inventory of the ones that are still around and was thrilled to spot this male Swift Setwing dragonfly (Dythemis velox) last week when I made a brief visit to Jackson Miles Abbott Wetland Refuge.

Swift Setwings are really cool-looking and are special to me. Five years ago I spotted my first one at this same refuge and it was the first time that a Swift Setwing, a primarily southern species, had ever been documented in Fairfax County, the county where I live. Every year since 2016 I have checked this location and found Swift Setwings—apparently this species has established a breeding population here, though I have seen no reports that it has ever been seen at any other spots in the county.

Swift Setwings perched in a distinctive fashion with their wings angled down and forward and their abdomen slightly raised, so they are pretty easy for me to identify. I was particularly thrilled when this individual chose and a particularly photogenic perch, allowing me to capture this rather minimalistic portrait of aSwift Setwing in early August.

Swift Setwing dragonflies

(You can see details of that first sighting in my 25 June 2016 posting Swift Setwing dragonfly.)

It seems pretty clear that there is now at least a small population of Swift Setwings now established at the small pond at this refuge. This past Thursday I spotted several Swift Setwings, all of which were male, and captured these images. As you can see, members of this species like to perch at the very top of the vegetation, usually facing the water. It can be quite a challenge to get profile shots like these and almost impossible to get the kind of head-on shots that I love to take.

Female Swift Setwing dragonfly

Posted in Dragonflies, dragonfly, Macro Photography, Nature, Photography, Summer, wildlife, tagged , , , , , , , on August 17, 2020| 13 Comments »

I was happy last Monday to finally get a shot of a female Swift Setwing dragonfly (Dythemis velox) at Jackson Miles Abbott Wetland Refuge—all of my previous photos this year have been of males. With some dragonfly species, like Common Whitetails, I generally see an equal number of males and females, but with other species, like the Swift Setwing, the females tend to hang out in different places than the males and are rarely seen. The female visits the location where they males are found—in this case, the pond—only when she decides that she is ready for mating.

The first image shows the typical wings-forward pose of Swift Setwings, which allows us to see the beautiful markings on the upper part of the abdomen of this female. In the second image, she has raised her wings into a position much like that of other dragonflies, which lets us get a better view of her face. As I recall, a breeze was blowing in the face of the dragonfly when I took the second shot and she may have raised her wings to reduce her profile and wind resistance.

First Swift Setwing of 2020

Posted in Dragonflies, dragonfly, Nature, Photography, Summer, wildlife, tagged , , , , , , on July 11, 2020| 24 Comments »

Some dragonfly species are special to me because of their beauty; some—because of their rarity; and some—because of the specific circumstance under which I found them. Swift Setwings are in the latter category.

Four years ago I photographed a strange-looking dragonfly at Jackson Miles Abbott Wetland Refuge and could not identify it. I was a little shocked when experts told me it was a male Swift Setwing dragonfly (Dythemis velox), a primarily southern species that had never before been spotted as far north in Virginia as Fairfax County where I live.

Every year since that first encounter, I make a pilgrimage to the spot of my first sighting to check on “my” dragonflies, which now seem to have a well-established breeding population. Alerted by a Facebook posting by a fellow photographer, I visited the refuge this past Tuesday and was thrilled to spot several male Swift Setwing dragonflies.

As you can see from the two photos below, Swift Setwings have a distinctive posture—they typically perch on the tip of branches with their wings angled down and forward and their abdomen slightly raised. Apparently the stance reminded some scientist of a sprinter at a track meet on the blocks in the “ready, set, go” position” and that is supposed to be the source of the somewhat unusual name for the species.

Usually the vegetation on which a Swift Setwing is perched hangs over the water and the dragonfly faces the water. As a result, I too often have to hang over the water to get a decent angle for a shot. So far, I have managed to keep from falling into the pond, though I must admit that I have come close to doing so a few times.

Swift Setwing in July

Posted in Dragonflies, dragonfly, Insects, Nature, Photography, Summer, wildlife, tagged , , , , , , on July 4, 2019| 4 Comments »

Yesterday I spotted this male Swift Setwing dragonfly (Dythemis velox) at Jackson Miles Abbott Wetland Refuge. Unlike most dragonflies that hold their wings straight out to the side, this species pulls its wings forward and adopts a ready-set-go position when perching.

This species is really special to me. A few years ago I had the first documented sighting of a Swift Setwing in the county in which I live and each year I am thrilled to see them again. Late in June I saw my first one this year, but was not able to capture any decent images, so these are my first successful Swift Setwing shots this season.

Swift Setwings like to perch on the end of vegetation overhanging the water and are always almost facing the water, which makes it tough to get shots without getting wet. One of the cool things about their perching patterns is that it usually allows me to get uncluttered backgrounds in the shots that I am able to take. In both of these images, the water forms a neutral background that almost makes them look like they were shot in a studio setting.

Swift Setwing dragonflies in flight

Posted in Dragonflies, dragonfly, Insects, Nature, Photography, Summer, wildlife, tagged , , , , , , , , on July 26, 2018| 7 Comments »

From time to time I will try to capture images of dragonflies in flight. Even under the best of circumstances it is a tough challenge for dragonflies are small, fast, and agile. Occasionally they will hover briefly, though most of the time it seems they choose to do so only when they are a long way away from me.

This past Monday I visited Jackson Miles Abbott Wetland Refuge and was surprised at the number of Swift Setwing dragonflies (Dythemis velox) that I observed there. As far as I know, this is the only location in our area where this species can be found. Swift Setwings are primarily a southern species, but seem to be migrating slowing northward.

Swift Setwings are  pretty small, about 1-6 to 2 inches long (42 to 50 mm), and the males, the only ones that I generally see, tend to perch at the edge of the water in overhanging vegetation. On this particular day, the dragonflies seemed to be particularly skittish, flying off as soon as I approached them. That was what prompted me to try to photograph them in flight. My Tamron 180mm macro is notoriously slow in focusing and tends to hunt a lot, so I switched to manual focusing. I made a lot of attempts and managed to get a few photos that were relatively in focus like the second image below.

While I was tracking one Swift Setwing in my viewfinder, a second one flew in and the two hooked up in mid-air in a mating position. They held the position for only a brief moment before disengaging and flying away in separate directions. I will spare you the anatomical details, but, as you can see in the first photo, dragonflies are quite acrobatic and flexible when mating.

So if you want a real photographic challenge, go out and see if you can capture some images of dragonflies in flight. It’s a fun challenge for me, even when I am not successful. If others see you doing so, it will reinforce the notion that wildlife photographers are a bit crazy, a perception that is accurate in many cases.

Ready, set, go—Swift Setwing

Posted in Dragonflies, dragonfly, Insects, Nature, Photography, wildlife, tagged , , , , , , , on June 24, 2018| 8 Comments »

Have you ever watched sprinters prepare for the start of a race? They get into their starting blocks and lean forward, ready to push off at the sound of the gun. Well, that’s what some scientist had in his mind when he first saw today’s dragonfly, the Swift Setwing (Dythemis velox). The forward tilting of the wings is very distinctive and makes this dragonfly easy to identify.

This is mostly a southern dragonfly and I was thrilled when I spotted one two years ago, the first time that a Swift Setwing had been documented in my county. Since then I have looked forward to finding them each year at Jackson Miles Abbott Wetland Refuge, where they appear to have established themselves.

Last weekend I spotted my first Swift Setwing of the season and I was able to capture these images.

Dragonfly geometry

Posted in Dragonflies, dragonfly, Macro Photography, Nature, Photography, wildlife, tagged , , , , , , , on September 20, 2017| 2 Comments »

Different dragonfly species rest in varying positions. Some of them hang vertically, but most of them perch at somewhat of an acute angle. Last week when I spotted this male Swift Setwing dragonfly (Dythemis velox), I was struck by the degree to which its rigid position reminded me of the diagrams of a right angle in my geometry textbook when I was a schoolboy—the dragonfly and the plant stem seemed to form an almost perfect 90 degree angle. One unusual thing about Swift Setwing dragonfly is the way that it holds its wings forward when perched and not straight out as most dragonflies do. Perhaps it helps to counterbalance the effects of gravity and helps it hold its abdomen so high for so long.

First Swift Setwing in 2017

Posted in Dragonflies, dragonfly, Insects, Macro Photography, Nature, Photography, tagged , , , , , , on June 20, 2017| 2 Comments »

Yesterday morning at Jackson Miles Abbott Wetland Refuge at Fort Belvoir, Virginia I spotted my first Swift Setwing dragonfly (Dythemis velox) of the season. Last year. I believe, was the first time one was spotted in Fairfax County, where I live, and it looks like they are here to stay.

I spotted this dragonfly from pretty far away and recognized the shape and perching style. I took a few shots and moved a little closer and took a few more shots. I was hoping to get even closer, but the dragonfly apparently sensed my presence and flew away. As it turned out, that was the only Swift Setwing that I saw all day. I am pretty confident, though, that I will have some more opportunities to photograph this beautiful little dragonfly in the upcoming weeks and, hopefully, months.

Swift Setwing dragonfly still with us

Posted in Dragonflies, Insects, Nature, Photography, Summer, tagged , , , , , , on August 25, 2016| 6 Comments »

On Monday I spotted this beautiful Swift Setwing dragonfly (Dythemis velox) at Jackson Miles Abbott Wetlands Refuge at Fort Belvoir, a nearby military base. When I observed one at the same location in June, it was the first time that one had been recorded in Fairfax County, the county in Northern Virginia where I live, so I was a little surprised to see that they are still around.

If you would like to see some photos of my initial sighting, check out my blog posting from June 25. The range of this dragonfly seems to be moving northward and it seems likely that I’ll be seeing this species again next year, since I suspect that mating and egg-laying have been taking place during the past two months.

Swift Setwing dragonfly

Posted in Dragonflies, Insects, Macro Photography, Nature, Photography, wildlife, tagged , , , , , , on June 25, 2016| 14 Comments »

Yesterday I spotted a very cool-looking, but unfamiliar dragonfly. I ended up posting an image in several Facebook groups in an effort to get an identification from some of the experts and was a little shocked to learn that it is a male Swift Setwing dragonfly (Dythemis velox), a primarily southern species that may never before have been spotted in Fairfax County, the county where I live.

It looks like this species is spreading northward. According to a posting on an Ohio natural history blog, this dragonfly species was spotted for the first time in Ohio in 2014 and a photo was posted today of a teneral female Swift Setwing in Champaign County, Ohio.

Why are these dragonflies called “setwings?” According to the blog posting cited above, setwings “spend a lot of time perched, typically on the tip of branches and frequently with their wings angled down and forward and their abdomen slightly raised…(the) English name of “setwings” (came) from this posture, which reminded them of a sprinter at a track meet on the blocks in the “ready, set, go” position.”
