With all of the hot weather we have been having recently, I have absolutely no desire to be as busy as a bee. I spotted this bee busily at work this past Tuesday morning at Occoquan Bay National Wildlife Refuge.

Temperatures in our area are forecast to rise to 100 degrees (38 degrees C) today and the high humidity will make it feel even more intolerable. I will probably spend most of the days indoors, but fortunately I have plenty of recent photos in reserve that I can process and post.

This image is the kind of simple shot that I really like. I remember my sense of wonder the first time I used a macro lens and I still feel excitement when I immerse myself in the details that a macro lens reveals.

Dragonflies perch in a lot of different ways. Some perch at the top of vegetation, some perch in the middle, and some, like this Unicorn Clubtail dragonfly (Arigomphus villosipes) like to perch low to the ground or, in this case, to the surface of the water. I don’t see Unicorn Clubtails very often, so I was excited to see this one on Tuesday at Occoquan Bay National Wildlife Refuge in a marshy pond filled with lily pads.

I had two cameras with me when I encountered the dragonfly. The second image below shows the view from my DSLR with a 180mm macro lens. I really like the way that the shot gives you a sense of the environment and when I was processing the image I paid as much attention to the surroundings as I did to the dragonfly.

My Canon SX50 let me zoom in a lot closer to the dragonfly, as you can see in the first shot, and captured more details of the dragonfly. I like aspects of both images and think that together they provided complementary views of this wonderful dragonfly. You can’t really see it in these shots, but members of this species have a little protrusion in between their eyes, which prompted someone to name them “unicorns.”

Yesterday I spotted this Common Wood Nymph butterfly (Cercyonis pegala) at the edge of a wooded area as I was exploring Occoquan Bay National Wildlife Refuge. Although the colors of this butterfly are somewhat muted, I really like the distinctive yellow patch that makes it easy to identify.

When I first saw the butterfly, it was on the ground and initially I was disappointed when it flew up into a tree. Fortunately, it perched on a leaf that was at eye level and I was happy to be able to capture this image.

Life can be tough and can wear you down if you are a prince, at least if you are a Prince Baskettail dragonfly (Epitheca princeps). Last Saturday I spent a pretty good amount of time observing Prince Baskettails patrolling a pond at Jackson Miles Abbott Wetland Refuge.

As I am wont to do, I tried to photograph them in flight and managed to get a few shots in focus. As I reviewed the images, I couldn’t help but notice that the wings of all of the dragonflies were worn down and/or damaged. I am used to seeing such damage with dragonflies that fly through thickets and heavy vegetation, but I was a little surprised to see it with dragonflies that seem to spend most of the time flying over open water.

As we move deeper into summer, I am certain to encounter more and more dragonflies with damaged wings. I am always amazed to see that such dragonflies are still capable of amazing aerial acrobatics despite their physical limitations—somehow they manage.

Normally a dragonfly’s abdomen is straight. Occasionally, though, I encounter one with an abdomen that has a noticeable curve, like this male Eastern Pondhawk dragonfly (Erythemis simplicicollis) that I spotted yesterday at Jackson Miles Abbott Wetland Refuge. (For those of you not familiar with dragonfly anatomy, the upper portion of the body is the thorax and the lower two-thirds is the abdomen.)

I suspect that the curvature was the result of a problem that occurred when the dragonfly was first emerging. It does not seem to have any effect on his ability to fly or to catch prey, but it might pose a problem when he attempts to mate.

Should I present a subject in landscape mode or portrait mode? That is a question I face frequently when I am composing photos initially and later when I am processing the images. Some subjects or scenes lend themselves naturally to one of the modes, but often it is not clear which one will be more effective. I remember reading somewhere that it is best to take shots from multiple angles, at varying distances, and using multiple modes and I try to follow that advice whenever I can.

This past week I encountered a large dragonfly as I was exploring a small creek in Prince William County, Virginia. The creek was mostly in the shadows and I was unable to identify the species of the dragonfly until it perched on a sun-lit tree. Then it was easy to determine that it was a Gray Petaltail dragonfly (Tachopteryx thoreyi).

The dragonfly was pretty cooperative and I was able to take multiple shots, two of which I have included in this posting. From an artistic perspective I particularly like the first image, which gives equal weight to the dragonfly and to the environmental elements. The second image draws your attention more to the details of the dragonfly and give greater emphasis to the texture of the tree.

Are you drawn more to one of the two images? If so, why? I know how I react to my own images and am always curious to hear what you think and/or feel about them.

A couple of weeks ago I posted a photo of a Black-shouldered Spinyleg dragonfly (Dromogomphus spinosus) that prompted one of my readers, Molly Lin Dutina of Treasures in Plain Sight, to comment, “Spinyleg —sounds like something a child would be afraid of!” That photo, alas, did not give a very good view of the spiny legs.

This week, however, as I was exploring a creek in Prince William County, Virginia, I was fortunate to capture some images of a Black-shouldered Spinyleg that show off those fearsome spines. If you click on the image below and focus your attention on the back legs, you will see the long pointed spines that help the dragonfly hold on to prey.

Ouch!

Yesterday as I was exploring a creek in Prince William County, Virginia I spotted this large damselfly. I marveled at its beautiful coloration and was happy to be able to capture an image that shows it off well. At the time I took the photo I was not certain of the species, but when I returned home and looked in my damselfly book, I learned that it is a male Powdered Dancer damselfly (Argia moesta).

As a Powdered Dancer male gets older, its thorax and the tip of its abdomen become covered with a powdery blue or gray substance in a process known as pruinescence. Eventually the male will look almost white, which makes it even easier to identify. So many damselflies have a lot of blue on their bodies that it is hard for me to be confident in my identification when I see a damselfly with blue coloration.

One of the real joys of the summer is having the chance to see colorful butterflies, like this Common Buckeye butterfly (Junonia coenia) that I observed last week at Jackson Miles Abbott Wetland Refuge. I am not sure what creature has been munching on the vegetation on which the butterfly is perched, but I really like the way that the holes in leaves mirror the circular shapes of the butterfly’s eye spots.

Do dragonflies have noses? That sounds like a crazy question, but it is the first one that came to mind when I looked at the image that I had captured of a dragonfly in flight this past week at Jackson Miles Abbott Wetland Refuge. I could not immediately identify it, so I consulted with experts in a Facebook group and learned that it is a Cyrano Darner (Nasiaeschna pentacantha). This species has a protruding forehead—it’s not a nose— that is reminiscent of the long nose of literary character Cyrano de Bergerac.

The species in the second shot is a Prince Baskettail (Epitheca cynosura), a species that I have featured multiple times in this blog. During much of the summer, I can usually spot one or two Prince Baskettail dragonflies patrolling over the pond at the same wetland refuge and I love trying to capture shots of them in flight. What makes this image distinctive, though, is not so much the dragonfly, but the background. There were ripples in the pond and the way that I shot and processed the image turned them into a wonderfully abstract background.

When I post photos like these, I often get questions about how I am able to capture images of flying dragonflies. Luck and persistence are the keys to getting shots like these. I use my 180mm macro lens and focus manually as the dragonflies zoom by, because the dragonflies don’t fill enough of the frame for my auto-focus to engage quickly and accurately. I have found that is almost impossible for me to use a zoom lens in this task—I get overwhelmed when I try to zoom, track, and focus simultaneously.

Do you suffer from recency bias? Recency bias is a type of cognitive bias that causes you to give greater weight in decision-making to things that have happened recently than to those that happened in the past, even the recent past. It is the only explanation I can come up with for not having already posted these shots of a Sable Clubtail dragonfly (Stenogomphurus rogersi) that I observed on 12 June.  Essentially, I got so caught up in excitement over newer photos that that I pushed this dragonfly out of my mind or at least off of my “To-do” list.

Sable Clubtails are rare in our area. Although I have searched for them repeatedly this season, including in a location where I saw some last year, this is the only one that I have seen in 2019. According to the website Dragonflies of Northern Virginia, “Sables appears to prefer small, relatively clean, shallow and stable forest streams, with plenty of low vegetation and a gentle flow.” That is a pretty good description of the stream in Prince William County, Virginia where I spotted this Sable Clubtail, but it also means that I am unlikely to stumble upon a member of this species at the ponds and marshes that I often visit.

In addition to being found only in a very specific type of habitat, Sable Clubtails have a very limited flight season—only a few weeks in length. That window of opportunity has almost certainly closed for the year. If you would like to see some additional photos of Sable Clubtails or read of my thoughts about chasing after rare dragonflies, check out this posting from a year ago.

Is the best image of a butterfly only one in which its wings are fully open so that you can see all of the beautiful colors and patterns? Generally that is the angle that most of us seek to shoot. This past Wednesday I was observing an Eastern Tiger Swallowtail (Papilio glaucus) at Jackson Miles Abbott Wetland Refuge when it struck me that the butterfly was “attacking” the flower from all kinds of different angles, even hanging upside down. Why shouldn’t I take the same approach with the butterfly (minus the hanging upside down part)?

I like the way in which the three shots below capture some of the activity of the butterfly and not merely its beauty. At times it seems like beauty and function are at odds with each other, that beauty is best captured in controlled settings like in a studio, where portraits are often taken.

I fully accept that the natural world in which I like to work is chaotic and out of my control, but in the midst of it I still find incredible beauty, a beauty that may be imperfect by some standards. I encourage you to look at your world from a different angle at least from time to time and you may be amazed by the way that a change of perspective can cause you to see things in a totally different way.

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.

I love to photograph birds and I love to photograph insects, so what could possibly be better than photographing an insect that looks and acts like a bird? Last week I was observing a patch of flowers at Jackson Miles Abbott Wetland Refuge when I spotted what looked like a large bee. As I got closer, I realized that it was a Hummingbird Clearwing Moth (Hemaris thysbe).

Like a hummingbird, this insect hovers as it gathers nectar from flowers. Instead of a long skinny beak, though, the Hummingbird Clearwing Moth uses its long proboscis to get to the nectar. As the second photo shows, the moth curls up its proboscis when it is not in use—in this case, the moth was preparing to fly off to another flower.

During a brief trip to Massachusetts last weekend, I photographed this beautiful damselfly, which I believe is an immature female Eastern Forktail damselfly (Ischnura verticalis), while exploring Horn Pond in Woburn.

When I looked at the range map for this species, it looked like it is not present in my home area of Northern Virginia. However, when I did a search of my blog postings, I was surprised to discover that I had previously photographed an orange Eastern Forktail at one of my favorite local spots. Obviously I am not someone who keeps a “life list” of all the species that I have seen and photographed. 🙂

Last Tuesday as I was exploring Occoquan Bay National Wildlife Refuge I spotted this handsome male Calico Pennant dragonfly (Celithemis elisa). Unlike some species that perch close to the ground and are hard to see, Calico Pennants perch on the uttermost tips of vegetation. Although they are visible, they are often hard to photograph, because their precarious perches start to sway at the slightest hint of a breeze.

On Monday I spotted this small patch of Butterfly Weed (Asclepias tuberosa) at Jackson Miles Abbott Wetland Refuge. True to its name, the Butterfly Weed had attracted several butterflies, which I think are Pearl Crescent butterflies (Phyciodes tharos), as well as several metallic green sweat bees (genus Agapostemon). The insects seemed to love the plant’s nectar and the scene provided a visual feast for viewers like me.

Although I love seeing my old familiar dragonfly friends, it is always exciting to observe new species. Last week while I was exploring in Prince William County, Virginia with fellow dragonfly enthusiast Walter Sanford, I spotted this dragonfly perched on a small tree. I really liked the pose and moved closer for some shots.

I initially thought it was a Needham’s Skimmer, a fairly common species in our area, but the more I looked at my photos afterwards on my computer screen, the more I began to note some differences in the colors and patterns on wings and the body. After consultations with some dragonfly experts on Facebook, I learned that it is a Yellow-sided Skimmer (Libellula flavida).

As far as I know, this is the first time that I have seen a Yellow-sided Skimmer. There is a possibility that I have unwittingly seen one in the past and dismissed it as “only” a common species.  I try not to do that, because this is not the first time that I have photographed something new without realizing until later that it was in fact new.

Dragonhunter dragonflies (Hagenius brevistylus) love to perch and wait for their prey to come by and then use their powerful back legs to snag that prey, which is often another dragonfly. Those legs are so long and ungainly, though, that Dragonhunters’ poses often seem awkward when they are perched—they remind me of teenage males who have undergone a recent growth spurt and haven’t gotten used to their longer limbs.

Last Friday as I was exploring a stream at Prince William Forest Park with fellow blogger and dragonfly enthusiast Walter Sanford, he spotted this female Dragonhunter perched at the edge of the water. I was walking toward him when I spotted the Dragonhunter on the rocks that I featured yesterday and was delayed in getting to see this dragonfly. Fortunately, she was relatively tolerant of our presence and remained in place long enough for me to get some shots.

All of the images that I captured show a side view of the Dragonhunter, because she was facing toward the water and I was trying not to get wet. Walter, however, wanted more of a frontal view  and waded into the water to get that shot. Check out today’s posting on his blog and you can compare the results of our different approaches.

Dragonfly on the rocks? It sounds like a summertime beverage, but it accurately describes what I saw last Friday while exploring a stream in Prince William County, Virginia with fellow dragonfly enthusiast Walter Sanford. I think it is a Dragonhunter dragonfly (Hagenius brevistylus), but the unusual angle makes it tough to made a definitive determination of the species, because I am not able to see critical portions of the dragonfly’s anatomy.

In the past when I have spotted Dragonhunters, they have been perched on branches overhanging the water and that is where I expect to find them. This encounter is a good reminder for me to stay alert at all times—my subjects may not have read the identification guides about how they are supposed to behave.

When the weather gets hot, some dragonflies will raise their abdomens (the “tail”) in what is believed to be an attempt at thermoregulation. I can’t say for sure if it works, but the theory is that in this position, sometimes referred to as the “obelisk,” dragonflies are able to stay cooler by reducing the amount of their bodies subject to direct sunlight.

Earlier this week I spotted this male Eastern Amberwing dragonfly (Perithemis tenera) in a modest obelisk position at Jackson Miles Abbott Wetland Refuge. I characterized the position as “modest,” because sometimes a dragonfly will elevated its abdomen until is almost vertical.Eastern Amberwing

When I spotted a small patch of milkweed while exploring Occoquan Bay National Wildlife Refuge earlier this month, I stopped and waited. I knew that numerous butterflies are attracted to this plant. Before long, several butterflies in fact appeared.

Here are photos of two of them, both swallowtail butterflies. The first one, a Spicebush Swallowtail (Papilio troilus), appears to be in perfect condition. Its wings and “tails” are intact and its colors are vibrant. By contrast the second butterfly, a Zebra Swallowtail (Protographium marcellus), is clearly a veteran. There are chunks missing from its wings and its long beautiful swallowtails are gone.

Do you find one of the butterflies to be more inherently beautiful than the other? Here in the United States, we tend to worship beauty and a standard of supposed perfection. We are daily bombarded with advertising messages that tell us we can look young again, that we can cover up our imperfections. The current focus on selfies and dating apps that allow you to judge others with a swipe encourages a kind of narcissism and attention to superficial appearances that I personally find to be unhealthy.

I remember watching a video several years ago about photographing nature. The photographer encouraged viewers to photograph only perfect specimens of flowers and insects, following the lead of those who say that in order to create beautiful photographs, you need beautiful subjects.

The photos here are my response to that kind of thinking. There is an incredible beauty to be discovered in the ordinary, everyday subjects that surround us, full of imperfections and blemishes. Take a moment today to slow down and truly experience that beauty.

Most of the times that I have observed a Common Sanddragon dragonfly (Progomphus obscurus) it has been perched directly on the sand, which makes sense, given its name. Last week, however, I spotted this Common Sanddragon perched in some vegetation overhanging the water of a stream in Prince William County, Virginia.

I like the way that the dragonfly almost looks like he is flying, because I managed to take the photograph from almost directly overhead, causing the perch almost to disappear. I also really like the look of rocky portion of the stream that makes up most of the background of this image.

I have not yet spotted any Monarch butterflies this season, but last week at Occoquan Bay National Wildlife Refuge I did see a number of the similarly-colored Viceroy butterflies (Limenitis archippus). Viceroy butterflies are smaller than Monarchs, but the main visual difference between the two is the black line across the hind wings that is present with Viceroys, but not with Monarchs.

I chased after one Viceroy last week for quite some time and eventually managed to get these shots.

Last week as I was exploring Prince William County, I encountered this large dragonfly  perched in a tree overhanging a fairly large stream. When I captured these images, I was not sure what kind of dragonfly it was. After consultations with some experienced dragonfly experts, I learned that this is a female Dragonhunter dragonfly (Hagenius brevistylus).

Dragonhunters are among the largest dragonflies in our area. Unlike darners, another group of large dragonflies that fly almost continuously as they seek prey, dragonhunters prefer to perch and wait patiently before they strike. As their name suggests, they specialize in hunting other dragonflies, reportedly including members of their own species.

This past Wednesday I encountered a really cooperative Gray Petaltail dragonfly (Tachopteryx thoreyi) as I explored nearby Prince William County and was able to capture this tight head shot. I simply love this dragonfly’s beautiful gray eyes, which are a perfect for the monochromatic palette of the rest of its body and give this dragonfly a more sophisticated look than many of its more gaudily-clad brethren. (The coloration also helps this dragonfly to almost disappear from view when it is perched on a tree like this one.)

I have often thought that Comet Darner dragonflies (Anax longipes) are appropriately named for they have always been beautiful objects speeding by that I have been forced to admire from a distance. It is hard to miss a Comet Darner when they are around because they are very large and the red color on their bodies is so bright that it seems to glow. They generally patrol near the center of the ponds where I have seen them and I have never seen one stop to perch. According to the Dragonflies of Northern Virginia website, “Comets have expansive territories that may cover several miles and a network of small, shallow, forest-edged ponds. They’ll visit your pond, leave for 30 minutes to patrol other sites, then return.”

On Wednesday, I spotted a Comet Darner while I was at a small pond and started to track it in my camera’s viewfinder. Strangely this dragonfly was flying in and out of the vegetation growing in the shallow water, as you can see in the first shot. As I was trying to figure out what was going on, the Comet Darner dipped her abdomen in the water and began to deposit her eggs. If you look closely at the second image, it looks like she may actually have the tip of her abdomen submerged as she oviposited. I didn’t have a completely unobstructed view of this beautiful dragonfly, but I actually like the effect of the vegetation in the foreground—it helps to convey the sense that we are sharing a private moment.

When it comes to photography, how do you balance its creative and technical components, how do you mix art and science? In the uncontrolled natural environment in which I take my photographs, I often have to be content with merely capturing an image, any image, of my subject before it disappears.

Sometimes, though, I can make minor adjustments on the fly that have a major impact on the final shot. Last week I was at Occoquan Regional Park, observing dragonflies as they zigged and zagged over the surface of the water. Most of them were common, readily identifiable species. Suddenly I spotted one that was different. I suspected, and later confirmed, that it was a female Unicorn Clubtail (Arigomphus villosipes) and knew that it was pretty rare to spot the female of this species.

The dragonfly began to dip the tip of her abdomen down in the water to deposit eggs and I sprung into action. She was not far from the shore and I snapped off a few shots looking down at her. Those images simply did not have any impact. Instinctively I dropped to my knees, which brought me closer to my subject. More importantly, it gave me a new perspective. I was closer to being at eye level with my subject and I was able to capture a more interesting background with the ripples in the water created by her actions.

This image, for me, is close to being an optimal mix of the technical and creative components of photography. It was challenging to shoot and simultaneously allowed me to express myself artistically. It is my response to the occasional naysayers who assert that photography is merely about capturing reality.

Last week at Occoquan Regional Park, I spotted a pair of Carolina Saddlebags dragonflies (Tramea carolina) flying in tandem.  I managed to capture this sequence of shots as the male released the female so she could deposit eggs in the water (ovipositing). Once she was done, he grabbed her again and they went on to the next spot.

After mating, male dragonflies and damselflies are concerned about protecting their reproductive efforts, lest a rival intervene and dislodge their sperm. Some males will circle overhead to fight off potential rivals while the female oviposits; some will hang onto her during the entire process; and a few will use the “catch and release” method illustrated in these images.

If you are interested in additional information about dragonflies and mating, I recommend an article on ThoughtCo.com entitled “How Dragonflies Mate–A Rough-and-Tumble Affair.” Some of you may be worried that this is some kind of scientific treatise, but it is not. To allay your fears and entice you to read the article, here is the opening paragraph of the article.

“Dragonfly sex is a rough-and-tumble affair. If you’ve ever seen a pair of mating dragonflies in the act, you know that their sexual coupling requires the flexibility and acrobatic skill of a “Cirque de Soleil” performer. Females get bitten, males get scratched, and sperm winds up everywhere. These strange mating habits have survived millions of years of evolution, so the dragonflies must know what they’re doing, right? Let’s take a closer look at how dragonflies mate.”

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!

Most dragonflies have clear wings, so I am happy when I see one with dark patches on its wings. It is even more exciting to see one with both brown and white patches, like this male Widow Skimmer dragonfly (Libellula luctuosa) that I spotted on Saturday at Occoquan Regional Park in nearby Lorton, Virginia.

When it comes to identifying dragonfly species, I have learned to focus not only on the colors of the wing patterns, but also on the number of such patches and their shapes. In the case of the Widow Skimmer, for example, both the males and females have the brown patches on the portion of the wings nearest the body.

Why are they called “Widow Skimmers?” Someone apparently thought the dark patches looked like the mourning crepe that historically widows wore. Even the Latin name “luctuosa” means “sorrowful.”

I used to be confused by the use of a female-associated word like “widow” with males, but I have gotten used to it. In fact, I no longer give a second thought to the idea of male damselflies, though I don’t have a clue about how that label affects their self-image.
