Autumn turtles

Posted in Autumn, Nature, Photography, Reptiles, wildlife, tagged , , , , , , , , on September 30, 2023| 4 Comments »

The weather is cooling off, but whenever there is the slightest amount of sunshine, I can count on seeing turtles basking in the warmth of the sun. This past Wednesday, I spotted these three turtles on a partially submerged tree branch in the small pond at Jackson Miles Abbott Wetland Refuge. I am pretty sure that the turtle on the right is a Red-eared Slider (Trachemys scripta elegans) and the other two may be Yellow-bellied Sliders (Trachemys scripta scripta).

I am always a fan of reflections and I love the way that we can see reflections of the turtles on the rippled surface of the water. It was an added bonus to have some patches of red, a sign of the changing season.

Rainbow grasshopper

Posted in Autumn, Insects, Macro Photography, Nature, Photography, wildlife, tagged , , , , , , , on September 29, 2023| 12 Comments »

On Wednesday at Jackson Miles Abbott Wetland Refuge I was thrilled to spot this rainbow-colored Handsome Meadow Katydid (Orchelimum pulchellum), which is probably my favorite insect. In addition to its multiple colors, I love its striking blue eyes and long antennae.

My title is a little misleading, because technically there are some differences between grasshoppers and katydids. One of the most visible differences is the length of the antennae—a katydid’s antennae are longer than the length of its body, while a grasshopper’s tend to be shorter. In the first photo, I cut off one of the antennae a bit when I cropped the photo, but if you look closely you can see that the antenna runs all the way to the left edge of the photo.

Shortly after I took the first photo, the katydid became aware of my presence and tried to hide from me. She stretched out her legs, which really elongated her body, and she was almost successful in concealing herself behind the stalk of grass.

How do I know that the katydid is a female? If you look closely at the tail end of the katydid in the first photo, you can see a red scimitar-shaped appendage. That is the ovipositor that the katydid uses to make a slit in vegetation in which to deposit her eggs.

Autumn Monarchs

Posted in Autumn, Butterflies, Insects, Nature, Photography, wildlife, tagged , , , , , , on September 28, 2023| 4 Comments »

At this time of the year, many of the butterflies that I see are showing the ravages of a long summer season. That, however, was not the case with several Monarch butterflies (Danaus plexippus) that I spotted last week at Occoquan Bay National Wildlife Refuge that appeared to be in perfect condition.

Perhaps these are newly emerged Monarchs that are now preparing for a long migration flight to warmer locations.

Last Needham’s Skimmer?

Posted in Autumn, Dragonflies, dragonfly, Insects, Nature, Photography, wildlife, tagged , , , , , on September 27, 2023| 2 Comments »

The weather this past week has been cool, cloudy, and rainy, with high temperatures struggling to reach 65 degrees (18 degrees C). I fear that many dragonflies will not survive and so I celebrate each sighting of a dragonfly species, conscious that it could be the last one that I see this season.

Last Thursday I spotted this Needham’s Skimmer dragonfly (Libellula needhami) while I was visiting Occoquan Bay National Wildlife Refuge. Its wings are tattered and its colors have faded, but it was still active.

Autumn often makes me pensive and I become more aware of the passage of time. Our lives are just as fragile and limited as those of the beautiful little insects that I am so fond of photographing. May we all find beauty, meaning, and love as we live our lives.

Red-footed Cannibalfly in September

Posted in Autumn, Insects, Nature, Photography, wildlife, tagged , , , , , , on September 26, 2023| 9 Comments »

Can you identify this insect? At first glance it looks a little bit like a dragonfly, but if you look more closely you may notice that the wings and eyes are different from those of a dragonfly and this insect’s body is a lot hairier. This is a robber fly and I am pretty sure that it is a variety known as a Red-footed Cannibalfly (Promachus rufipes). Yikes!

Red-footed Cannibalflies are one of the coolest and creepiest insects that you can encounter in the wild. As their macabre moniker suggests, Red-footed cannibalflies usually feed on other insects, but they reportedly are capable of taking down a hummingbird. Thankfully I have never seen that happen, since I really like hummingbirds, but several years ago I did photograph a Red-footed Cannibalfly with a large Hummingbird Moth that it had captured (see my 2017 posting Demise of a hummingbird moth).

A posting that I did in 2013 entitled “Red-footed Cannibalfly” amazingly has been one of my most popular postings ever, with almost 3300 views to date. Apparently more people search for information about Red-footed Cannibalflies that I would have anticipated.

I captured this image last Thursday as I was exploring some of the trails at Occoquan Bay National Wildlife Refuge in Northern Virginia.

Perching Black Saddlebags dragonfly

Posted in Autumn, Dragonflies, dragonfly, Insects, Nature, Photography, wildlife, tagged , , , , , , , on September 25, 2023| Leave a Comment »

I was happy last Thursday when a Black Saddlebags dragonfly (Tramea lacerata) that I had been tracking overhead at Occoquan Bay National Wildlife Refuge perched for a moment, allowing me to capture this first image.  While it was flying, I attempted multiple times to get a shot of it, with minimal success. The second photo is my best one.

Some dragonflies spend a lot of their time perched, but Black Saddlebags are one of the species that spends most of its time in the air, so it is rewarding to be able to see one land and to get a shot of it. Black Saddlebags are also one of the few dragonfly species that are migrate although, according to the Dragonflies of Northern Virginia website, scientists do not fully understand why they do so and have been studying their migratory patterns.

Lesser Yellowlegs

Posted in Autumn, Birds, Nature, Photography, wildlife, tagged , , , , , , on September 24, 2023| 1 Comment »

I almost always have trouble identifying shore birds, especially the different kinds of sandpipers. On Thursday, I spotted a single sandpiper-like bird in the shallow water of a pond at Occoquan Bay National Wildlife Refuge. Initially I thought it might be a Solitary Sandpiper, but when I got a good look at its legs, I leaned towards calling it a Lesser Yellowlegs (Tringa flavipes)—Solitary Sandpipers have greenish legs.

It was fascinating to watch the little bird move through the water, carefully raising its feet. On land, it seemed to prance a bit. In the final photo, the bird was flexing its wings as part of its grooming routine and seemed to be keeping an eye on me.

Brown Thrasher

Posted in Autumn, Birds, Nature, Photography, wildlife, tagged , , , , , , on September 23, 2023| 4 Comments »

When I stepped out of my car on Thursday at Occoquan Bay National Wildlife Refuge, I notice a bird pecking about in the grass at the edge of the parking lot.The lenght of its tail made me think of a Northern Mockingbird, but the coloration was more sparrow-like. As I tracked the bird in my camera’s viewfinder, the bird lifted its head and I caught a glimpse of its bright yellow eye and realized that it was a Brown Thrasher (Toxostoma rufum), a species that I have seen only a few times before.

I really like the basic description of the species on the Cornell Lab of Ornithology website—”It can be tricky to glimpse a Brown Thrasher in a tangled mass of shrubbery, and once you do you may wonder how such a boldly patterned, gangly bird could stay so hidden. Brown Thrashers wear a somewhat severe expression thanks to their heavy, slightly downcurved bill and staring yellow eyes, and they are the only thrasher species east of Texas. Brown Thrashers are exuberant singers, with one of the largest repertoires of any North American songbird.”

Blue Grosbeak

Posted in Autumn, Birds, Nature, Photography, wildlife, tagged , , , , , on September 22, 2023| 8 Comments »

I was not able to get close to this Blue Grosbeak (Passerina caerulea) on Monday at Occoquan Bay National Wildlife Refuge, but was thrilled to get a shot that was good enough for me to identify the bird. As far as I know, this is the first time that I have photographed a Blue Grosbeak.

When I first spotted this bird, I thought that it was probably an Indigo Bunting.  When I got home and looked more closely at the images, however, I noticed the reddish wing bars that are not found on an Indigo Bunting, so I scoured my bird identification book until I came across the Blue Grosbeak.

These two shots illustrate well the dilemma I have in photographing small birds at this time of the year. Many of them like to perch high in the trees and the leaves often hide them from view. When I hear a bird singing, I try to locate it, but am usually unsuccessful in doing so unless the bird moves. In a month or so, many of the leaves will be gone, but so will many of the birds that are now passing through our area.

Wild turkeys in the brush

Posted in Autumn, Birds, Nature, Photography, wildlife, tagged , , , , , , on September 21, 2023| 1 Comment »

On Monday I spotted these two Wild Turkeys (Meleagris gallopavo) at Occoquan Bay National Wildlife Refuge as they climbed a small hill through some tall grass. They kept disappearing from view, but occasionally their heads would pop up and I was able to capture a few shots of them.

The bodies of the turkeys are partially hidden by the vegetation, but I really like the way that I was able to capture a sense of the habitat in which I saw the turkeys. Normally I spot turkeys in the open on the trails at this wildlife refuge, so it was cool to see them traveling “off-road.”

More Monarchs in September

Posted in Autumn, Butterflies, Insects, Nature, Photography, wildlife, tagged , , , , , , on September 20, 2023| 1 Comment »

On Monday I was thrilled to spot multiple Monarch butterflies (Danaus plexippus) during a visit to Occoquan Bay National Wildlife Refuge. The first shot is the typical kind of shot that I usually try to take, but I really like the third image that I captured of a distant Monarch butterfly in a field of flowers—so many flowers, so little time.

Russet-tipped Clubttail in September

Posted in Autumn, Dragonflies, dragonfly, Insects, Nature, Photography, wildlife, tagged , , , , , , , on September 19, 2023| Leave a Comment »

For the last few weeks I have been searching diligently for the late-season dragonfly species that appear on the scene in late August and early September. So far I have come up mostly empty-handed, but I was thrilled to spot this cool-looking Russet-tipped Clubtail dragonfly (Stylurus plagiatus) on 6 September at Jackson Miles Abbott Wetland Refuge. In my area, Russet-tipped Clubtails  are seen most often in August and September, but they are somewhat uncommon.

As some of you know, I dabble a bit with YouTube. At about this time last year I did a little video about Russet-tipped Clubtails that you might enjoy watching. It was one of my first videos and lasts about a minute and a half.  Click on this link to view the video in YouTube. I am also embedding a YouTube link at the end of this posting. Depending on how you are reading this blog, you may be able to watch the video from within the blog.

A year ago, I had aspirations of shooting more video footage during my photography outings. I have made only minor progress in that area, but it is still something that interests me a lot. I have learned the basics of making and editing videos, but am struggling to figure out what stories I want to tell and how a video can help me tell those stories.

Damsels in distress

Posted in Arachnids, Autumn, damselfly, Insects, Nature, Photography, spiders, wildlife, tagged , , , , , , , , on September 18, 2023| 3 Comments »

As we move deeper into September I have been seeing more and more Black and Yellow Garden Orbweaver spiders (Argiope aurantia). These spiders are impressively large and have prominent webs with a distinctive zigzag pattern near the center.

During recent visits to Occoquan Bay National Wildlife Refuge, I have seen multiple Big Bluet damselflies (Enallagma durum) that have gotten caught up in the webs of the Argiope spiders. In the first photo the spider is moving in on two damselflies. After immobilizing the prey, the spider will often wrap it in web material, as you can see in the second image.

The final shot shows a hapless damselfly entangled at the edge of a web. I observed the damselfly for a few moments to see if I could detect any signs of movement, with thoughts that I might be able to free it. However, I did not see any movement and suspect that I had arrived too late to rescue this damsel in distress.

Some viewers may object to these kind of graphic images, but for me it is part of the “circle of life” in nature—all creatures have to eat to survive. As I have observed numerous times, today’s predator may well become tomorrow’s prey.

Dragonflies in September

Posted in Autumn, Dragonflies, dragonfly, Insects, Nature, Photography, Summer, wildlife, tagged , , , , , , , , , , , , , , , on September 17, 2023| 10 Comments »

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.

Dragonflies in the air

Posted in Autumn, Dragonflies, dragonfly, Insects, Nature, Photography, wildlife, tagged , , , , , , , , , , on September 16, 2023| 2 Comments »

Dragonflies were flying overhead at several locations at Occoquan Bay National Wildlife Refuge on Thursday, including a Common Green Darner (Anax junius), multiple Black Saddlebags (Tramea lacerata), and at least one Wandering Glider (Pantala flavescens). The Wandering Glider, alas, was elusive and I could not get an in-flight shot of it, but I did manage to get a shot of a Common Green Darner (1st photo) and a Black Saddlebags (2nd photo).

All three of these dragonfly species are migratory species. Migrating dragonflies will often fly in mixed swarms that are large enough that they are sometimes picked up by weather radars. For more details about this phenomenon, check out this September 2019 article in the Washington Post entitled “Weather radar is picking up swarms of dragonflies from the Midwest to the Mid-Atlantic.”

Heron at water’s edge

Posted in Autumn, Birds, Nature, Photography, wildlife, tagged , , , , , on September 16, 2023| 2 Comments »

On Thursday at Occoquan Bay National Wildlife Refuge I captured this image of a Great Blue Heron (Ardea herodias) at water’s edge. Heron’s are quite large and normally are easy to spot.

However, as I was approaching this area, this Great Blue Heron was initially hidden from view by the metal posts sticking out of the water, as you can see in the second photo. Fortunately the heron’s head was turned to the side and it was the bird’s large bill that gave away its presence. I had to walk farther down the trail and look back to get the viewing angle for the first photo in which the heron is somewhat separated from the posts and is more visible.

Autumn Vibes

Posted in Autumn, Dragonflies, dragonfly, Insects, Nature, Photography, wildlife, tagged , , , , , , , , , , , on September 15, 2023| 1 Comment »

For those of us in the northern hemisphere who use the astronomical calendar, tomorrow (23 September) marks the beginning of the autumn season. In so many of the photos that I have taken during the past few weeks, I have noted signs of the changing seasons.

The warm orange tones in this shot of a female Needham’s Skimmer dragonfly (Libellula needhami) remind me of pumpkins and autumn leaves. The fading flowers in the photo of a male Common Whitetail dragonfly (Plathemis lydia) remind us that the growing season is coming to an end. The dryness of the stalk on which the Slaty Skimmer (Libellula incesta) dragonfly perch brings to mind the droughts and extreme weather that many have experience during this summer.

Embrace the new season and the opportunities is provides, whether it be autumn in the northern hemisphere or spring for those in the southern hemisphere.

White-banded Crab Spider

Posted in Arachnids, Autumn, Flowers, Nature, Photography, spiders, wildlife, tagged , , , , , , on September 14, 2023| 10 Comments »

On Monday I captured this shot of a small white spider—I think it may be a White-banded Crab Spider (Misumenoides formosipes)—at Occoquan Bay National Wildlife Refuge. I really like the way that the coloration of the tips of the spider’s leg are an almost perfect match for the spiky thorns of the vegetation. In the second photo, the spider looks a lot like a crab in the way that it is shaped and was moving—it’s easy to see why it is called a “crab” spider.

Changing season

Posted in Autumn, Birds, Nature, Photography, wildlife, tagged , , , , , , on September 13, 2023| Leave a Comment »

At this time of the year we experience the change in seasons in many different ways. We feel the gradual cooling of the weather. We see the changing colors of the leaves on the trees. We hear (and see) the unmistakable sound of flocks of migrating Canada Geese (Branta canadensis).

Although we seem to have a resident population of Canada Geese in our area year-round, during the spring and summer large flocks of geese fly through our area and it is quite common to hear the loud honking of the geese as they fly overhead. Sometimes they fly in military precision in a v-formation, but more often than not they are in a looser formation, as was the case with these Canada Geese that I photographed last week while I was looking for dragonflies at Jackson Miles Abbott Wetland Refuge in Northern Virginia.

Dragonfly and aster

Posted in Autumn, Dragonflies, dragonfly, Flowers, Insects, Nature, Photography, Summer, wildlife, tagged , , , , , , , on September 12, 2023| 11 Comments »

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.

Wild Turkey Wingspan

Posted in Autumn, Birds, Nature, Photography, Summer, wildlife, tagged , , , , , , , on September 11, 2023| Leave a Comment »

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.

Monarch in September

Posted in Butterflies, Insects, Nature, Photography, Summer, wildlife, tagged , , , , , , , , on September 10, 2023| 4 Comments »

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.

Swift Setwing dragonfly in September

Posted in Autumn, Dragonflies, dragonfly, Insects, Nature, Photography, Summer, wildlife, tagged , , , , , , on September 9, 2023| 5 Comments »

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.

Viceroy in September

Posted in Autumn, Butterflies, Insects, Nature, Photography, Summer, wildlife, tagged , , , , , , , on September 8, 2023| 4 Comments »

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.

Twelve-spotted Skimmer in September

Posted in Autumn, Dragonflies, dragonfly, Insects, Nature, Photography, Summer, wildlife, tagged , , , , , , on September 7, 2023| 2 Comments »

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.

Late Season Black Swallowtail

Posted in Butterflies, Insects, Nature, Photography, Summer, wildlife, tagged , , , , , , on September 6, 2023| 4 Comments »

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.

Biological imperative

Posted in Autumn, Dragonflies, dragonfly, Insects, Nature, Photography, Summer, wildlife, tagged , , , , , , , , , on September 5, 2023| 2 Comments »

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.

Surprise catch

Posted in Birds, Nature, Photography, Summer, wildlife, tagged , , , , , , , , on September 4, 2023| 4 Comments »

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.

Tattered skimmer

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.

Carolina Saddlebags finally perched

Posted in Dragonflies, dragonfly, Insects, Nature, Photography, Summer, wildlife, tagged , , , , , , on September 2, 2023| 1 Comment »

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
