As I have mentioned previously, I have real difficulties in identifying many of the dark swallowtails that I encounter. However, sometimes I get a perfect view of one and the task is vastly simplified.
Last week at Occoquan Bay National Wildlife Refuge, for example, I spotted this Spicebush Swallowtail butterfly (Papilio troilus) feeding on a blooming thistle plant. I could tell it was a Spicebush Swallowtail because its row of inner orange spots was interrupted by a swoosh of blue that looks a bit like the tail of a comet. Additionally, the position of the butterfly made for a beautiful composition of the image that I was able to capture.

I had not seen a Swift Setwing dragonfly (Dythemis velox) in several weeks at Jackson Miles Abbott Wetland Refuge and feared that they might be gone for the season. I was therefore thrilled when I spotted this one last Thursday. Most of the previous times when I have seen Swift Setwings, they have been perched with their wings pulled forward, but this one had its wings fully extended.
A bit later that same day, I spotted a Swift Setwing that appeared to be missing an entire wing, as you can see in the second photo below. I looked carefully at other shots of the same dragonfly and in a couple of them I can see at least a partial wing in that spot. It is interesting that I did not notice this problem with the wing while out in the field, and the dragonfly flew away without any issues whatsoever.

Recently I have featured numerous large, beautiful butterflies feeding on blooming plants, especially thistles. Today, I decided to turn the spotlight to the smaller, more nondescript butterflies, commonly referred to as skippers, that have been equally active and visible in recent weeks.
According to Wikipedia, there are more than 3500 species of skipper butterflies in the world and many of the species are visually similar in appearance. For that reason, I am especially cautious in trying to identify one of these small butterflies. Sometimes I will request assistance in identifying specimens in one of many Facebook groups to which I belong. I have learned the “secret” to getting a response—if I make a misidentification, some experts who might not help me with an identification will feel compelled to correct me.
I spotted the little beauty in the photo below last week while I was exploring a patch of flowers at Jackson Miles Abbott Wetland Refuge. It might be a Peck’s Skipper (Polites peckius), but to me it looks a bit more like a Zabulon Skipper (Poanes zabulon). Whatever the case, I like the way that I was able to capture the butterfly in action, sipping nectar with its proboscis fully extended.

Some dragonflies will look me straight in the eye, but others, like this male Blue Dasher dragonfly (Pachydiplax longipennis), seem to prefer sidewards glances. I spotted this cute little dragonfly last Thursday at Jackson Miles Abbott Wetland Refuge. Blue Dasher dragonflies are among the first dragonflies to appear on the scene in the spring and among the last ones to disappear in the autumn.
The vegetation at this time of the year is always interesting, a combination of new growth and dried-out stems. I love both the colors and textures of the perch that this dragonfly had selected and the visible cobwebs add a nice touch of visual interest to the image.

I spotted this spectacular Great Spangled Fritillary butterfly (Speyeria cybele) last week at Occoquan Bay National Wildlife Refuge. Although I usually have something to say about an image, in this case I will let it speak for itself. Suffice it to say that I love the wonderful combination of the pink of the flower and the orange of the butterfly. Wow!

We are definitely in a period of time when butterflies are everywhere, especially in the patches of thistles that are blooming now. Earlier in the week I spotted this beautiful male Eastern Tiger Swallowtail (Papilio glaucus) at Occoquan Bay National Wildlife Refuge as he was feeding on a thistle. I was delighted to capture a shot when the butterfly had his wings fuly extended, showing off all the details of the wings.
In case you are curious, you can tell that the butterfly is a male because he lacks the band of blue spots along the hindwings that are found on the females of the species.

On Monday I spotted these cool-looking black- and-red beetles at Occoquan Bay National Wildlife Refuge. I think that they are immature Florida Predatory Stink Bugs (Euthyrhynchus floridanus), a species considered to be beneficial, because its diet consists of many species of pest insects. The nymphs of this species go through five stages (instars) in their growth process and I believe these bugs are in one of the later stages of development.

The leaves are still on the trees, which makes it tough for me to spot perched birds, which is one the reasons why I focus on insects in the summer months. Nonetheless, I tend to scan the trees when I am out with my camera, hoping to spot a bird perched in the open.
On Monday at Occoquan Bay National Wildlife Refuge, I spotted an unfamiliar shape through the foliage as I was hiking along one of the trails. As I moved a bit to the side to get a better view, I realized that it was a Great Blue Heron (Ardea herodias). Now I know that herons will roost in the trees at night, but it is a little unusual for me to see on in a tree at midday. The bird appeared to be keeping an eye on something, almost like a sentinel, though I have no idea on what its attention was focused.
I moved slowly and stealthily to get a better shooting angle and eventually captured this image of the heron. As you can see in the photo, the heron was definitely alert and paying attention—it did not appear to be relaxing in the tree. Maybe the heron felt like the king of the world and was taking a moment to survey his realm.

There has been a relatively recent resurgence of butterflies in my area. In the past week or so I have seen more butterflies than at any other time this summer. Several of the dark swallowtail butterflies, though, are similar in appearance and are hard to tell apart, especially when wing damage hides some of the features that I rely on for identification.
Last week at Occoquan Bay National Wildlife Refuge, I spotted this beautiful dark swallowtail as it was feeding on a thistle plant. I can’t tell for sure, but I think that it may be a Spicebush Swallowtail butterfly (Papilio troilus). A chunk of the hind wing is missing, but otherwise the butterfly seems to be in good shape. It was moving around a lot on the thistle, but I was patient and eventually was able to capture a decent shot of this beautiful creature.

How old does a dragonfly have to be to collect Social Security? OK, that’s a bit of a crazy question, but collecting Social Security is a sure sign that you are getting old. A couple of weeks ago, I received my first payment from the Social Security Administration, a sure sign that I am officially “old.” Last week I also stopped in a a Metro offices in Washington D.C. to sign up for a senior pass that allows me to ride Metro trains at a reduced rate—one of the few tangible benefits of becoming a senior.
Here in the United States, people are living longer than in the past and it is anticipated that the Social Security Administration will run out of money to pay full benefits in a decade or so of changes are not made. Politicians don’t want to deal with the issue and keep putting off coming up with a solution to the problem.
Comparatively speaking, dragonflies live uncomplicated lives. They hang on for as long as they can and then they die, hopefully after successfully procreating. Last week I spotted this elderly female Great Blue Skimmer dragonfly (Libellula vibrans) at Occoquan Bay National Wildlife Refuge. Her coloration was dark and faded and her wings were tattered, but she was still functioning. After spending a few quiet moments with her, I pushed onward, still lost in my thoughts about life and growing older.

I’ve noted several times recently the tattered butterflies that I tend to encounter at this time of the year. However, not all of the ones that I see have suffered wing damage. Some of them appear to have recently emerged and are in perfect condition, like these Eastern Tiger Swallowtail butterflies (Papilio glaucus) that I spotted during a recent visit to Occoquan Bay National Wildlife Refuge.

I love to see dragonflies with patterned wings and so I was delighted to spot this male Twelve-spotted Skimmer dragonfly (Libellula pulchella) on Tuesday at Occoquan Bay National Wildlife Refuge. The males of this species have a beautiful combination of brown and white patches on their wings.
I used to be confused about the name of the species, because there appear to be a total of twenty-two spots. To make things worse, this species is also known as the Ten-spot Skimmer. What? It apparently depends of how you count the spots. If you count only the brown spots that are present on both males and females, you get twelve spots, but if you count the white spots that are present on only the males, you get ten spots. Yikes! Who knew that math was so important in dragonfly identification. 🙂

Earlier this summer Needham’s Skimmer dragonflies (Libellula needhami) were among the most common dragonflies that I would see at Occoquan Bay National Wildlife Refuge. The last month or so, however, their numbers have declined significantly and they are now quite hard to find. I was delighted, therefore, to photograph this slightly tattered female Needham’s Skimmer on Tuesday morning.
Our weather has cooled off this week, with early morning temperatures in the 50’s (10 degrees C) and daytime highs struggling to get to 80 degrees (27 degrees C). I looked at the 10-day weather forecast and see that temperatures are not predicted to hit the 90’s (33 degrees C). Now it would be premature to declare that summer is over and we may well have some hot days in store for us, but the seasons are definitely changing.
So I will continue to search for remaining dragonflies while again, hopeful that I will spot some of the autumn species, like the Autumn Meadowhawks and Blue-faced Meadowhawks that should be appearing soon. Personally, autumn is my favorite time of the year, with cool nights and warm, sunny days, but I am not yet ready to bid farewell to the summer.

On Tuesday I spotted a really cool-looking butterfly at Occoquan Bay National Wildlife Refuge, a Red-banded Hairstreak (Calycopis cecrops). This species has distinctive reddish-orange markings across its hind and forewings. I don’t recall seeing this species very often, though I have included photographs of the butterflies in some blog postings in the past.
The Red-banded Hairstreak is quite small in size, with a wingspan of just over an inch (25 mm), so I had to focus very carefully on the butterfly to obtain a sharp image. I was pleasantly surprised by the results with my Tamron 18-400mm zoom lens that did a pretty good job in capturing a shot of such a small subject.

The countdown begins. Now that we are into September, the number of dragonfly species is beginning to drop and many of the remaining ones are looking a little tattered. They seem to adapt and compensate for their disabilities while moving, perhaps, a bit more slowly.
Yesterday at Occoquan Bay National Wildlife I photographed a number of male Slaty Skimmer dragonflies (Libellula incesta). Their dark bodies and eyes make them pretty easy to identify. Some of them appeared to be in pretty good condition, like the one in the first photo, while others, like the one in the second photo, are showing the signs of a tough summer.
Aging in all species is inevitable. No matter how much we complain about it, we are fortunate if we are able to slow its effects—we cannot stop it. The 19th century French romantic poet Alphonse de Lamartine wrote about the passage of time in a famous poem called Le Lac (The Lake) that included these words:
“Just a few more moments, I ask — in vain, for time
Eludes me and takes flight.
I tell the night to pass more slowly, and dawn comes
To chase away the night.
“Then let us love! Then let us fill each fleeting hour
With joy and ecstasy!
Man does not have a port; time does not have a shore.
It passes, and so do we.”

During a recent visit to Occoquan Bay National Wildlife Refuge I spotted quite a few Red Admiral butterflies (Vanessa atalanta), a fairly common species where I live. When I did a little research on-line, I learned that, according to Wikipedia, Red Admirals, also known as Red Admirables, are found in temperate regions of North Africa, North and Central America, Europe, Asia, and island regions of Hawaii, and the Caribbean. Wow!
I remember in the past that I sometimes referred to this species as a “patriotic” butterfly, because it had red, white, and blue areas in its coloration. I was happy to capture this shot of a Red Admiral with its wings partially open, because it gives you an idea of the interior colors as well as the exterior colors of the butterfly. As you can see, the inside of the wings feature wide reddish-orange stripes.

In those parts of the world that use a meteorological calendar, autumn arrived on the first day of September. The rest of us will have to wait until the 22nd of this month to mark the official changing of the season. As I have noted in some previous postings, I have already noted the decrease in several dragonfly species and the overall numbers of dragonflies will continue to drop during September.
It is also common for me to see butterflies with damaged wings at this time of the year. I marvel at the ability of butterflies to survive with a significant amount of damage to their wings. Last week I spotted this Common Buckeye butterfly (Junonia coenia) during a visit to Huntley Meadows Park. The butterfly was missing the lower portions of both of its wings, but somehow was still able to fly.
I recall reading somewhere that the purpose of the large eyespots on the wings of butterflies is to fool predators into attacking those portions of their bodies, thereby protecting their more vulnerable body parts. I don’t know it that was the case with this butterfly, but it may well be the cause of the damage that it has sustained.
Autumn often fills me with a vague sense of melancholy and I acutely feel the passage of time. Some aspects of life inexorably will come to a close or enter a state of dormancy.
I try desperately to hold on to the summer, but a part of me knows that change is inevitable. Enjoy the remaining portions of the season.

I was delighted to spot this Great Spangled Fritillary butterfly (Speyeria cybele) feeding on a thistle flower during a recent visit to Huntley Meadows Park, a county-run wetland not far from where I live in Northern Virginia. I have not seen many of this species of butterfly this season, so I was happy to capture this artsy artsy shot of the Great Spangled Fritillary on the one open bloom of the thistle plant.
I love the way that they spiky unopened buds add visual interest to the image without drawing attention from the primary subject.

Earlier this week I watched a distant Great Egret (Ardea alba) as he stared at the waters at Huntley Meadows Park. Initially he was standing tall, but slowly the egret bent over, carefully balancing himself on a floating tree trunk. We both watched and waited until the moment came when he plunged his head into the water. I fired off some shots, wondering if the egret had caught a fish.
I can’t say for certain that the egret was unsuccessful, but it sure looks to me like there was no fish in his bill as he withdrew his head from the water. It appeared to me like the egret was fishing for tiny fish, because he did not plunge his head very deep into the water. After this attempt, the egret stood upright and relaxed for a few moments, before eventually resuming his efforts.
I moved on, wishing him the best of luck in his pursuit of his next fish, as I continued to hunt for dragonflies.

There must be something irresistible about thistle flowers, because on Tuesday I encountered multiple clusters of thistles with butterflies feeding on them during a short visit to Huntley Meadows Park. Sometimes the butterflies seemed to be socially distancing themselves, but at other times they were feeding side by side with other butterflies, including those of different species.
Of course, butterflies do not remain still while feeding—they move about constantly as they change their positions and flap their wings, complicating my efforts to capture images of them. The first photo below is one of my favorites. It shows a dark morph female Eastern Tiger Swallowtail (Papilio glaucus) sharing a thistle flower with two Great Spangled Fritillary butterflies (Speyeria cybele). I love the contrast between the colors of these two species that together provide a foretaste of the autumn season that is almost upon us.
The second photo provides a closer view of the dark morph Eastern Tiger Swallowtail. The final photo is a shot of what I believe is another female Eastern Tiger Swallowtail that has a yellow coloration similar to that of a male, but has an additional band of blue spots along the hindwings. I think it is really cool that there are two different color variants of females—in many insect and bird species, the males have more color and variation and the females are drab by comparison.

I love to search for Monarch butterflies, but this year I have spotted only a few of them. I am more likely to spot the similar looking Viceroy butterfly (Limenitis archippus), like this one that I photographed last week at Occoquan Bay National Wildlife Refuge. It paused for a moment as it perched high in the vegetation at the edge of the water of the bay and I captured the moment as the butterfly looked out on the watery expanse.
What was the butterfly thinking? I sometimes wonder what it would be like to be able to fly freely like a butterfly. Perhaps the butterfly was imaging what it would be like to swim like a fish.
We always are a little restless, wanting to be different from what we are. Maybe we should spend more time celebrating who we are in the present moment, a unique combination of strengths and weaknesses. As one of my brothers likes to say, “Be yourself—everyone else is already taken.”

I chased this small orange butterfly around for quite a while before it finally landed. Only then was I able to determine that it was probably a Variegated Fritillary butterfly (Euptoieta claudia), a species that I do not see very often. I looked over my old blog postings and discovered that most of my sightings of this species have been late in the season—earlier in the season I tend to see the somewhat similar-looking Great Spangled Fritillary more often.
We have had a decent amount of rain recently, so there is still a lot of green in the vegetation that provides a nice contrast with the orange and brown tones of the butterfly. Those colors somehow remind me of the imminent arrival of the fall season. There is still a bit of the summer to enjoy, however, so I am not quite ready to jump ahead to the autumn—I prefer to live in the moment and celebrate what is in front of me in the present moments.

Last Friday I spotted this Black Swallowtail butterfly (Papilio polyxenes) as it was feeding on a thistle plant at Occoquan Bay National Wildlife Refuge. I love the shape, color, and texture of these thistle plants. I was a little shocked to see the excellent condition of the butterfly this late in the season.
When I returned home I did a little research and found out that this butterfly has at least two broods each year, with the second one flying at least until the end of August. Sometimes there is a partial third brood. Perhaps the butterfly in the photo recently emerged.
The later broods will lay eggs and winter is spent in a chrysalis stage. In the springtime, the adults will emerge and the cycle will continue. Nature is amazing!

I do not see deer very often at Occoquan Bay National Wildlife Refuge. A few times a year, the refuge is closed for for a few days for deer hunting, so I know that there must be plenty of deer, but they remain hidden most of the time.
On Friday I photographed a White-tailed Deer (Odocoileus virginianus) at the refuge. It was part of a group of at least four deer that I spotted as they grazed alongside the trail that I was following. Three of the deer moved into the brush on the side of the road as soon as they detected my presence, but one remained in place and stared at me with what appeared to be curiosity.
I had the impression that the deer was young, though I must confess that I have so little experience with deer that I have no idea how to tell their age. The deer appeared to be in good health. Some of my fellow photographers are virulently against hunting, but I recognize that deer overpopulation is a problem in our suburban area. Periodic hunting is a viable way of controlling the population size, though I personally am not a hunter and do not even own a gun.
My goal is to capture images with my camera of the wonders of the natural world and I felt blessed to be able to spend a few moments with this beautiful creature. After a few moments of staring at each other, the deer slowly made its way into the vegetation and disappeared from sight.

Early in the summer, Needham’s Skimmers (Libellula needhami) were among the most common dragonflies at Occoquan Bay National Wildlife Refuge. As the dragonfly season begins to wind down, their population size has been noticeably dwindling. I am still likely to see some of them, but I have to search a lot harder than I did a month or two ago.
Yesterday I captured this image of a female Needham’s Skimmer. She is in pretty good shape overall, with only a small portion of her wings looking a little tattered.
I like the way that this image shows the bright yellow veining near the leading edges of her wings, one of the distinctive identifying features of this dragonfly species. (The mature males are bright orange or red in coloration, making them even easier to identify.)

I really like Blue Dasher dragonflies. They are quite common and visible throughout most of the summer. Unlike some other dragonfly species that require specific habitats, Blue Dashers (Pachydiplax longipennis) can be found almost anywhere.
I really like the description of the species on the Dragonflies of Northern Virginia website, one of my favorite resources for information about the dragonflies in my area:
“A very little guy in a big hungry world, Blue Dashers make up for their small size with plenty of moxie. Just about everything eats them…but it certainly hasn’t affected their numbers. The most abundant dragonfly in our area, they face their predator-filled worlds head on. Males aggressively defend their small, shore-line territories against larger skimmers, and spend a great deal of time with their black-tipped abdomens pointed high in the air – an aggressive threat display. It’s also a technique used to cool down by reducing surface area to the sun, called the obelisk position. However, Dashers use it more than other species, and half the time it appears to be done for the purpose of territorial display, rather than temperature control.”
I spotted this Blue Dasher on Monday at Jackson Miles Abbott Wetland Refuge. I couldn’t get really close to the dragonfly, but like the way that the abundant vegetation helped to frame the dragonfly.

This female Slaty Skimmer (Libellula incesta) that I spotted on Monday at Jackson Miles Abbott Wetland Refuge has definitely seen better days. Its wings are growing tattered and its color has darkened with age. Nonetheless, the dragonfly is carrying on and compensating as it grows older. In fact, the dragonfly seemed to be feeding on some kind of insect when I photographed it.
A few weeks ago I turned 70 and I have become increasingly conscious of the passing of time. Tomorrow is not guaranteed, so I am trying to pay more attention to living my life in the moment, as perhaps this aging dragonfly is doing.

The countdown continues, but the dragonfly season is not over yet. I will undoubtedly continue to spot dragonflies for the next few months, but already their numbers seem to be diminishing as summer prepares to give way to autumn. We have had a series of cooler days this week, but I’m quite confident that summer is not quite ready to give up its hold and next week the high temperatures are forecast to return to the 90s.
I was happy on Monday to spot a Swift Setwing dragonfly (Dythemis velox) at Jackson Miles Abbott Wetland Refuge, the only one that I managed to photograph during my visit. I did have another sighting of a Swift Setwing that I was unable to photograph, but I am not sure if it was the same individual or a different one.
In the past, I have seen a Swift Setwing as late as September, but there are no guarantees that they will continue to be around that long this year. The population of Swift Setwing dragonflies is pretty well-established at this location, but it is quite small.
Each year I try to document my dragonfly sightings as we start to approach the end of the season, so I will probably return to this location again in the upcoming weeks. There are a few late-season species, like the Russet-tipped Clubtail, that will start to reappear, so I will keep my eyes open for them as well.

Eastern Amberwings (Perithemis tenera) are one of the smallest dragonfly species where I live—less than one inch (25 mm) in length. I often see the amber-colored males buzzing around at the ponds that I visit, but it is pretty rare for me to spot a female.
Yesterday I visited Jackson Miles Abbott Wetland Refuge and was a bit surprised to see a female Eastern Amberwing dragonfly in the vegetation near the edge of a small pond. Unlike the males, females of these species have patterned wings that are partially clear. I maneuvered around to composed a shot and managed to capture this image of the dragonfly.
According to the website Dragonflies of Northern Virginia, one of my favorite dragonfly websites, female Eastern Amberwing dragonflies are often found far from the water in meadows where they share perches with hornet and other wasps. When they are threatened, these dragonflies will rhythmically move their wings up and down while pulsing their abdomens in imitation of a wasp to scare off potential predators that believe they are about to be stung.
I don’t know if this female was checking out the males at the pond, searching for a suitable partner, or perhaps had just mated and was recovering from the experience. Whatever the case, I was delighted to spot this elusive little dragonfly.

With most dragonfly species, the male is usually the one with the most distinctive coloration and females are often nondescript in appearance. That is definitely not the case with the Eastern Pondhawk dragonfly (Erythemis simplicicollis), where the female is bright green and has distinctive black bands on her abdomen. She also has a green face that makes it almost impossible to misidentify this species.
Immature males of this species have a similar coloration to that of the female, but they are gradually transformed into a duller shade of blue and finally a powdery bluish-gray. The terminal appendages of the male are different from those of the female and additionally the ovipositor of the female, the egg-laying organ, is frequently visible below the tip of her abdomen, as you can see in this photo that I took last week at Occoquan Bay National Wildlife Refuge.
Eastern Pondhawks are quite common in my area, though this year I have not seen as many as in previous years. Although other dragonflies are equally fierce predators as the Eastern Pondhawk, the majority of the times that I have seen a dragonfly with prey, particularly other dragonflies or damselflies, it has been an Eastern Pondhawk.

I thought that the Calico Pennant dragonflies (Celithemis elisa) might be gone for the season, so I was thrilled to spot this handsome male last Monday (12 August) at Occoquan Bay National Wildlife Refuge. Calico Pennants are among the most colorful dragonflies that I encounter, with beautiful patterned wings. Early in their development, male Calico Pennants have yellow bodies, like their female counterparts, but eventually they become a bright red in color.
When I captured this image of the Calico Pennant, he was perched at the very tip of the vegetation, a favorite perching spot for this species. Like other pennant species, Calico Pennants often occupy precarious perches that cause them to flap like a pennant when even the slightest breeze is blowing.
