I do not see Carolina Saddlebags dragonflies (Tramea carolina) very often and when I am lucky enough to spot one, it is almost always in flight. According to the Dragonflies of Northern Virginia website, “Carolina Saddlebags appear to stick to shallow, thickly vegetated ponds and marshlands,” which is a pretty good description of the place where I spotted this one last Tuesday at Occoquan Bay National Wildlife Refuge. The same website described the Carolina Saddlebag’s flight tendencies as “Strong flier, often high, rarely perches.”

I spent some time that day watching several male Calico Pennant dragonflies, which are red and has patterned wings, as they flew around over the pond—check out yesterday’s posting to see a photo of a perched male Calico Pennant.  Suddenly a larger red dragonfly flew into view—Calico Pennants are approximately 1.3 inches (33 mm) in length, while Carolina Saddlebags are 2.0 inches (51 mm). I visually tracked the Carolina Saddlebags for a while and was able to follow it as it perched high on a stalk of vegetation in an adjacent field.

I was shooting into the light and at a sharp upward angle, which meant that I risked creating a silhouetted image of the back side of the dragonfly. I crouched a little to create a sky/trees background and waited for the dragonfly to give me a profile view. For a brief moment, my wishes came true and I captured the image below.

The image is far from perfect, but I like the way that it turned out. The focus on the dragonfly is a little soft, but I think it works well with the blurred background, creating an aesthetically pleasing little image.

When male Calico Pennant (Celithemis elisa) dragonflies are immature, they have yellow markings on their bodies similar to those of the females. As the males mature, those markings turn bright red. I was thrilled to spot several mature male Calico Pennants last week at Occoquan Bay National Wildlife, the first adult males of this species that I have encountered this year.

The bright body markings and the prominent wing patches really make this dragonfly stand out, although they are quite small, about 1.2 inches (30 mm) in length.

I spotted quite a few beautiful Zebra Swallowtail butterflies this past Tuesday at Occoquan Bay National Wildlife Refuge. The all seemed to be in constant motion, rarely perching for more than a split second and flying in unpredictable patterns.

Eventually I was able to capture a shot of a distant Zebra Swallowtail when it stopped to sip from a milkweed plant. I really like the composition of the photo, despite the fact that the main subject occupies only a small portion of the frame.

I could not help but notice that the butterfly is looking a bit tattered, with its long swallowtails already gone. Later in the season, I am sure that I will see many more butterflies and dragonflies with damage to their wings from the wear-and-tear of daily life. I am always amazed by the way that they are able to compensate and continue to survive. As I get older and slow down a bit, I try to remind myself to focus on those things that I can do and not on the ones that may be becoming increasingly challenging for me.

There has been a recent explosion of dragonflies at Occoquan Bay National Wildlife Refuge, my favorite location for photographing these beautiful aerial acrobats. I spotted hundreds and hundreds of dragonflies this past Tuesday as I explored the trails at the refuge.

One of the species that I encountered most frequently that day was the Needham’s Skimmer (Libellula needhami). The Dragonflies of Northern Virginia website provided a wonderful description of the Needham’s Skimmer. “This dashing summer dragonfly, a member of the king skimmer genus, makes quite a splash at the shallow, marshy wetlands it prefers. Relatively skittish, it spends more time on the wing and less time perching than other king skimmers.”

At this time of the year the males and females have a similar coloration, but as they mature the males will turn reddish-orange. The dragonfly in this photo is a female—it is easy to tell from the terminal appendages at the end of the abdomen. I love the bright yellow vein on the wings of this dragonfly, a feature that is shared by the males as well as the females of the species.

The breeze was kicking up a bit and this Halloween Pennant dragonfly seemed to be holding on for dear life when I spotted in on Tuesday at Occoquan Bay National Wildlife Refuge. It seems to be that it would be safer and more secure to grasp the stalk a bit lower, but, like other members of the pennant family of dragonflies, this Halloween Pennant is a bit of a thrill seeker.

As the old adage, often attributed to John A. Shedd, states, “A ship in harbor is safe, but that is not what ships are built for.” Sometimes, I think, it is good for us to step out of our comfort zones, which can turn into ruts if we are not careful, and take a risk by living life on the edge, like this Halloween Pennant dragonfly.

I was excited to spot this female Unicorn Clubtail dragonfly (Arigomphus villosipes) on Tuesday at Occoquan Bay Wildlife Refuge, one of the few times that I have seen a female of this species. I am not sure if the females hang out in different areas from the males, which perch prominently on low vegetation or logs at water’s edge, or if, like some human females, they are simply playing “hard to get” and wait to meet the males on their own terms.

As noted on the excellent Dragonflies of Northern Virginia website, Unicorn Clubtails are “the only clubtail in Northern VA that prefers ponds and marshes, over streams and rivers…our only clubtail that can be found in completely still, stagnant water.” I know that is true for the males that I have featured already a couple of time this season on this blog, but is it also true for female Unicorn Clubtails?

How do you explain the behavior of females? It is one of the mysteries of life.

After mating, many male damselflies hold on to the female as she deposits eggs in order to keep any rival males from interfering with the process. The male grasps the head of the female with the terminal appendages of his abdomen in the “tandem” position and the two linked damselflies move about from spot to spot as the female inserts eggs into floating vegetation.

Last Friday at Jackson Miles Abbott Wetland Refuge I managed to capture this image of a Slender Bluet (Enallagma traviatum) couple as the female arched her body, made a little slit in the vegetation and inserted eggs, a process known as “ovipositing.”

I am not absolutely certain I have correctly identified the damselfly species—there are a lot of bluet species—but I have made my call primarily on the basis of the markings on the abdomens of the male and the female. I intend to post this shot in a dragonfly/damselfly forum on Facebook and will update this posting if one of the experts in the group corrects my initial identification.

During a short visit to Jackson Miles Abbott Wetland Refuge last Friday I spotted my first Banded Pennant dragonfly (Celithemis fasciata) of the year. Pennant dragonflies like this one often perch precariously on the very tips of vegetation, which causes them to flap about in even the slightest of breezes, like a pennant.

Banded Pennants are somewhat uncommon and in some years I have not seen a single one, so I was happy to encounter this handsome male, the only one I saw all day. As you can see in all of the photos below, the dragonfly’s upper left wing did not seem to straighten out as much as the other three wings. From what I could see, though, the dragonfly was able to fly quite well despite this injury or deformity.

I was thrilled to spot my first Swift Setwing dragonfly (Dythemis velox) of the season this past Friday 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.

Eight years ago I spotted my first Swift Setwing dragonfly ever 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.)

Swift Setwings like to perch facing the water on overhanging vegetation, so it is a challenge to get a shot of one without getting my feet wet.  I had to find a little visual tunnel through the vegetation to get this shot, but I did manage to stay dry.

There must be something special about this perch. One week after I photographed a Unicorn Clubtail dragonfly (Arigomphus villosipes) on a log at the edge of a small pond at Occoquan Regional Park, I  spotted another Unicorn Clubtail in the exact same spot. Perhaps it was even the same individual, hanging out in the same old places, as this wildlife photographer is wont to do.

The edge of the pond is very mucky, so I couldn’t get any closer to give you a better view of the little “horn” that sticks up between the eyes and gives rise to the name “unicorn.” You’ll have to trust me on that point or check out a 2017 blog post entitled Unicorn in Northern Virginia that includes a better view of the unicorn “horn.”

We are in the midst of a real heat wave, with daily temperatures soaring into the mid-90’s (35 degrees C), so my wildlife forays are shorter than normal. Don’t worry, I am taking it slow, seeking shade whenever possible, and carrying water with me. Forecasters predict that this heat wave will continue for at least another week.  Yikes!

When I spotted this Gray Petaltail dragonfly (Tachopteryx thoreyi) on Monday at Occoquan Regional Park, I could see that it was feasting on some kind of insect that it had caught, but I could not get close enough to identify the prey. Dragonflies are fierce predators that feed on a wide variety of insects, sometimes including other dragonflies or damselflies.

When I examine the image carefully I can just make out the wings and legs and possibly an eye of the victim, but that does not help me to identify it. The dragonfly was perched high on the trunk of the tree and when I tried to move closer to get a better shot, the sharp angle made it even harder to see what was going on. I was happy enough to capture this profile view of the Gray Petaltail, which would otherwise have been pretty well camouflaged by the rough bark of the tree.

Many dragonflies have transparent wings that seem to disappear when they are flying, making them look even smaller and hard to detect. Male Widow Skimmer dragonflies (Libellula luctuosa), however, have such large bi-colored patches on their wings that they look almost like butterflies when in flight, an impression heightened by the fluttering way that they fly.

I was thrilled when I spotted this male Widow Skimmer—the females of this species do not have the white wing patches—on Monday at Occoquan Regional Park. The dragonfly flew by me numerous times and I watched and waiting, hoping that it would land.  My patience eventually paid off and I was able to capture this shot that shows off its wings beautifully. This may not be the most artistic image that I have ever captured, but it is a good one to use for the purpose of identification.

One of the coolest things about photography is that it can be both scientific and artistic, allowing me to be as geeky as I want in either domain.

In many of my blog postings, I concentrate on a single species of dragonflies, but today I want to celebrate the diversity of species that I have been seeing during the month of September. Despite my warnings in some earlier postings about the decreasing numbers of dragonflies, I continue to see a variety of species—Northern Virginia, where I live, is blessed to have an abundance of different dragonflies and damselflies.

The first photo shows a female Eastern Amberwing (Perithemis tenera), the smallest dragonfly in our area.  Males of this species hang out at ponds, but the females, which do not have amber wings like the males, are usually found in vegetation some distance from the water.

The second image shows a male Calico Pennant (Celithemis elisa), a beautifully colored dragonfly with distinctive patterns on its wings. The third image shows a mature female Needham’s Skimmer (Libellula needhami). Her wings show some damage and her color has fades, but she is still beautiful and the golden strands on the front edges of her wings were sparkling in the sunlight when I captured this image.

The fourth image shows a female Eastern Pondhawk (Erythemis simplicicollis), one of the most common dragonfly species in my area. I love the brilliant emerald color of the females (and immature males) of this species and the black markings on the abdomen.

The dragonfly in the last photo was the toughest one for me to identify. It had flown up into a tree and I was looking into the sun when I captured the image. However, I am pretty sure that it is a female Great Blue Skimmer (Libellula vibrans).

All of these dragonflies belong to the Skimmer family, the largest dragonfly family that includes the species most likely to be seen by a casual dragonfly watcher. The other families, which are generally harder to find, include Clubtails, Cruisers, Darners, Emeralds, Petaltails, and Spiketails. If I remember correctly, I have managed this season to photograph at least one dragonfly in all seven of these dragonfly families.

Wings are tattered. Flowers have faded. Summer is ending. (Blue Dasher dragonfly (Pachydiplax longipennis) photographed on 6 September at Jackson Miles Abbott Wetland Refuge.)

I don’t often see dragonflies perch on flowers, so I was delighted when this female Blue Dasher (Pachydiplax longipennis) decided to rest for a moment on an aster plant in bloom last week at Jackson Miles Abbott Wetland Refuge.

I decided not to crop this photo to show the dragonfly better, because I really like the sweep of bright color on the left side of the image and the more muted out-of-focus colors on the right side. I am growing to love this type of environmental portrait, which goes against my normal approach of trying to fill as much of the frame as possible with my primary subject.

As I was observing some Wild Turkeys (Meleagris gallopavo) last Thursday at Occoquan Bay National Wildlife Refuge, one of them suddenly decided to stretch a bit and flapped his wings. In the past I have seen a turkey extend its wings like this only when running away from me. In this case, though, the turkey went back to pecking on the ground and either was not aware of my presence or was simply not bothered by it.

Perhaps he was just trying to cool off on what was a really hot, humid day.

Certain creatures, like Bald Eagles (Haliaeetus leucocephalus) and Monarch butterflies (Danaus plexippus), never fail to thrill my heart when I encounter them. I remember dire warnings from my youth of their threatened extension and I consider it a real blessing that they are still around. The Bald Eagle population has really rebounded, but it is my understanding that the survival of Monarchs is still at risk as a result of the loss of Monarch breeding habitats.

I did not see any Bald Eagles during my visit to Occoquan Bay National Wildlife Refuge this past Thursday, but I was excited to spot this stunning Monarch butterfly. Its colors were bright and vibrant and it seemed to be in perfect condition. I suspect that this butterfly was preparing itself for its upcoming migration flight. According to an article by the National Wildlife Federation, “Beginning in late summer and continuing into early fall, monarchs that emerge from their chrysalides will be behaviorally and biologically different from generations that emerged earlier this year. Unlike their parents and grandparents, these late-season monarchs do not mate or lay eggs. Instead, the insects focus on feeding to fatten up for long migrations to their winter habitats: coastal California for monarchs west of the Rocky Mountains and central Mexico for those to the east.”

The Monarch butterfly was so focused on feeding that it did not fly away as I maneuvered into position to capture this image. I even had the luxury of attempting shots from several angles as the butterfly moved about from flower to flower.

Do you prefer to live your life widely or deeply? That is a curious question, but it is one that affects the way that many of us approach our photography and our lives in general. Let me reframe the question. Are you always seeking to visit new places to see new things, i.e. living “widely”, or would you rather spend your time in familiar locations with familiar subjects, going back to the same places repeatedly, i.e. living “deeply?”

As you may have guessed, I tend to put myself in the second category. I like to observe the seasonal changes at a few local areas, watching for new species to arrive and to depart (or disappear), observing the changes in the flora and the fauna, and discovering favorite spots for my photography. I am not really consumed by a need or desire to add to my “life list” of birds or insects that I have seen, though I do enjoy visiting other locations.

All of these thoughts were percolating in my brain on Wednesday when I visited Jackson Miles Abbott Wetland Refuge to see which dragonflies were still present. I was particularly delighted to spot several Swift Setwing dragonflies (Dythemis velox). In June 2016 at this same refuge, I first photographed a Swift Setwing—a primarily southern species that had never before have been spotted in Fairfax County, the county where I live—and each year since I have eagerly returned to learn more about the species. For more details on my initial sighting, check out my 2016  blog posting Swift Setwing dragonfly.

It is always tough to frame shots of Swift Setwings, because they like to perch on vegetation that overhangs the water and they face the water. The sun was shining brightly and I was happy to capture a couple of images in which the dragonfly appears to be perching among the clouds. I did try to get down low, but I think the background is a reflection of the sky in the water of the pond and not the sky itself.

For the second image, I was far away from the dragonfly. I couldn’t get a clear shot of the Swift Setwing, so I chose to use some vegetation blocking my view as a framing element in the foreground. I like the way that the image turned out.

On Wednesday I spotted this beautiful Viceroy butterfly (Limenitis archippus) during a short visit to Jackson Miles Abbott Wetland Refuge. At one end of the refuge, there is a patch of wildflowers and I always make sure to check it out for birds, butterflies, and other insects. I am no expert on wildflowers, but I think the purple plant in the photo may be a variety of ironweed.

As you can probably tell, the Viceroy is considered to be a mimic of the somewhat larger Monarch butterfly. They are pretty easy to tell apart, however, because the Viceroy has a black line across the hind wings that is not found on the wings of Monarchs.

From a distance, many dragonflies are hard to identify. However, the wing markings on a male Twelve-spotted Skimmer dragonfly (Libellula pulchella) are so distinctive that I could identify this dragonfly immediately when I spotted it yesterday in the marshland at Jackson Miles Abbott Wetland Refuge.

If you take the time to count all of the spots on the wings of the dragonfly, you come up with a number much higher than 12. Why then is it called a Twelve-spotted Skimmer? Someone decided that it was best to count only the dark spots, because only the males generally have the white spots. It is a rare case when gender equality seems to have factored into the name of a species—normally species’ names are based on the characteristics of the male.

I am happy that I continue to see quite a few butterflies during my visits to Occoquan Bay National Wildlife Refuge. Summer is definitely not over yet—today’s high temperature is forecast to be 97 degrees (36 degrees C) with a heat index well above 1oo degrees (38 degrees C)—but increasingly I am seeing signs that the seasons are starting to change.

I spotted this Black Swallowtail butterfly (Papilio polyxenes) recently as it fed upon some kind of leafy plant. The butterfly’s “tails” were fully intact, but there seemed to be a little damage to its wings and the wings seemed to be strangely separated from its body in the first photo. I am not sure if this is normal or not.

I am trying to decide if I will venture out into the heat today, seeking some of the late season dragonflies, like the Blue-faced Meadowhawk and the Fine-lined Emerald, that emerge onto the scene in early September. If I do go out, I will be sure to bring lots of water and will stay in the shade as much as I can.

The clock is ticking as we move towards the end of the dragonfly season and I see a lot of mating dragonflies that appear to be driven by the biological imperative of ensuring the perpetuation of their species. Late in August I observed this pair of Blue Dasher dragonflies (Pachydiplax longipennis) at Occoquan Regional Park in the mating position that is sometimes referred to as “the wheel.”

When mating is completed, the female, the lower dragonfly in the photo, will may lay 500 or more eggs by flying low over the water usually near a heavily vegetated pond edge and repeatedly tapping her abdomen to the surface. Once the eggs hatch, the life cycle of a dragonfly larva begins as a nymph that live underwater and eat smaller aquatic insects. The nymphs, also referred to as naiads, live underwater for up to two years and shed their exoskeletons six or more times.

According to an article in Cambridge Day, “When a naiad is ready to metamorphose into an adult dragonfly, it swims to the surface at night. There, it lifts its head out of the water as its body adapts to breathing air, then climbs a plant stem out of the water, where its skin splits behind its head and the adult dragonfly emerges. The adult swallows air to plump up its body and pumps hemolymph, the bloodlike substance of insects, into its wings.”

For more information about the life cycle of Blue Dasher dragonflies, check out these postings at Life on CSG Pond and at Cambridge Day.

The vegetation seemed so thick in the marshland at Jackson Miles Abbott Wetland Refuge that I was surprised that a Great Egret (Ardea alba) was able to spot and catch a fish there last Monday. I have not seen many egrets this year, so I was shocked to see five of them that day.

Great Egrets leave our area and head to warmer locations when the weather begins to turn cooler, while their “cousins,” the Great Blue Herons, stay with us throughout the entire year.

As we flip the pages of our monthly calendars from August to September, it is not unusual for me to encounter dragonflies with tattered wings. For many of these dragonflies, it has been a long, tough summer and they will only be with us for a few more weeks or perhaps a month or two. Despite the damage to their wings, the dragonflies appear to be fully capable of flight—somehow they are able to compensate for their infirmities.

I spotted this Great Blue Skimmer dragonfly (Libellula vibrans) this past Monday at Jackson Miles Abbott Wetland Refuge. It is a little tough to tell in this image, but several of the wings showed wear-and-tear. The shredded appearance of the vegetation is a perfect complement to this late season dragonfly—they both speak to me of the inexorable passage of time and the inevitable changes in our appearance and capabilities brought on the aging process.

I do not see Carolina Saddlebags dragonflies (Tramea carolina) very often and when I am lucky enough to spot one, it is usually in flight. According to the Dragonflies of Northern Virginia website, “Carolina Saddlebags appear to stick to shallow, thickly vegetated ponds and marshlands,” which is a pretty good description of the place where I spotted this one last Saturday at Occoquan Bay National Wildlife Refuge. The same website described the Carolina Saddlebag’s flight tendencies as “Strong flier, often high, rarely perches.”

I had been watching several Calico Pennant dragonflies, another species that is red and has patterned wings, as they flew around over the pond when suddenly a somewhat larger red dragonfly flew into view—Calico Pennants are approximately 1.3 inches (33 mm) in length, while Carolina Saddlebags are 2.0 inches (51 mm). I visually tracked the Carolina Saddlebags and was able to follow it as it perched high on a stalk of vegetation in an adjacent field.

I moved slowly and stealthily, but did not have room for maneuver to compose a few shots. The lighting was best when from the angle at which I captured the first shot and you can see some of the details and markings on the dragonfly’s body. In the second image, you get a better look at the “saddlebags,” the reddish-brown patches on the rear wings, but most of the body is silhouetted.

For the third shot, I changed the height of my shooting angle to make the background a bit more interesting than the sky. The blurry greenish background in the image was some distant trees. As you may have noticed, the dragonfly’s position in the second and third images is almost the same

Calico Pennant dragonflies (Celithemis elisa) often remind me of pole vaulters. They hold on to a long, narrow “pole” at the very end and flex it, as though they were trying to propel themselves over a bar. I spotted this handsome male Calico Pennant last Saturday at Occoquan Bay National Wildlife Refuge, one of the few local spots where I encounter this spectacular species.

This will probably be my last blog posting this week. I will be driving from Virginia to Massachusetts later today to deal with some family issues and will return home this coming weekend, when I hope to resume my habit of posting nature and wildlife photos almost daily.

I spotted this handsome male Widow Skimmer dragonfly (Libellula luctuosa) this past Saturday at Occoquan Bay National Wildlife Refuge. Only the males of this species have white patches on their wings—the females have only the dark patches.

The Latin name for this species includes the word “luctuosa,” which means “sorrowful” or “mournful.” Apparently someone thought that the dark patches on the wings of dragonflies of this species looked like the kind of mourning crepe veils that traditionally widows were supposed to wear up to four years to show their grief.

I think that I have been reading too many warnings about people taking advantage of older people, because the name “Widow Skimmer” initially conjured up visions of young gigolos chasing after rich old ladies in Florida who have lost their husbands.

I inadvertently spooked a Great Blue Heron (Aredea herodias) on Wednesday at Occoquan Regional Park and captured this first image as it flew up to a perch high in a nearby tree. It was really cool to see the heron’s impressive wingspan as it came in for a landing in the tree. The second image shows the Great Blue Heron as it surveyed its surroundings from its new perch.

When I was just starting out in wildlife photography, I remember being shocked the first time that I saw a Great Blue Heron in a tree. I somehow had assumed that they spent all of their time in the shallow water or at the edge of ponds. Little did I know at that time that Great Blue Herons build their nests in the trees and often spend their nights roosting in trees to protect themselves from potential predators.

Last Monday I spotted this striking female Halloween Pennant dragonfly (Celithemis eponina) perched high in the eastern gamagrass (Tripsacum dactyloides) at Occoquan Bay National Wildlife Refuge. It was somewhat unusual for me to have a chance to photograph a dragonfly above eye level and I did my best to isolate the subject against the pale blue sky.

I really like the minimalism of this composition.  The color and texture of the gamagrass add some visual interest to the image without distracting the viewer from the primary subject.

I was excited to spot this beautiful Eastern Tiger Swallowtail butterfly (Papilio glaucus) on Monday at Occoquan Bay National Wildlife Refuge. Most years I spot lots of these butterflies, but for some reason I have not seen one in quite some time this summer.

I love the beautiful coloration of this Eastern Tiger Swallowtail and believe that it is a female. Males of this species are almost exclusively yellow and black, while females are more vividly colored, with strongly pronounced cells of orange and a greater degree of iridescent blue on the lower wings.

The gloomy feel of this photo seems perfect for these two Black Vultures (Coragyps atratus) that I spotted in a dead tree on Monday at Occoquan Bay National Wildlife Refuge. Many people find vultures to be creepy, probably because they feed on the carcasses of dead animals. I remember too watching cowboy movies when I was growing up in which vultures would be circling overhead, waiting for people to die in the desert wastelands.

There were lots of vultures circling overhead on Monday and in situations like that, I jokingly tell people that I try to move about a lot, lest the vultures mistake me for a potential meal.  In my area, we have both turkey vultures and black vultures. They are pretty easy to tell apart, because turkey vultures have very distinctive red heads and black vultures have black heads. According to the Cornell Lab of Ornithology, “Whereas Turkey Vultures are lanky birds with teetering flight, Black Vultures are compact birds with broad wings, short tails, and powerful wingbeats. The two species often associate: the Black Vulture makes up for its poor sense of smell by following Turkey Vultures to carcasses.”

The light was coming mostly from behind the two birds, which created the silhouette-like effect that you see in the image below. I lightened the shadows a little, but I like the starkness of the almost monochromatic view of these birds in which most of their details are suggested, but hidden. I think it works well with the simple structure of the branches of the dead tree. Unlike most of my images that concentrate on detailed views of my subjects, this image is more about mood and shapes.
