Some people get creeped out by spiders, but many of them are quite beautiful, like this tiny Orchard Orbweaver spider (Leucauge venusta) that I spotted on Wednesday in Prince William County. The sun was shining brightly on the shiny body of the spider, so I underexposed the image intentionally, which is why it looks so dark in the photo—the background was green in real life. I was also leaning my lens against a branch for stability, since even the slightest movement at such close range can blur an image.

Orchard Orbweavers are really common where I live, but I suspect that most people do not look closely enough at them to see their beautiful colors. According to the LSU AgCenter, “Orchard spiders are .13 to .3 inches (3.5 to 7.5 mm) in length, with females typically larger than males.” I believe that the aforementioned measurements are for the body alone and do not include the legs.

In addition to capturing some of the beautiful colors of the Orchard Orbweaver, I was thrilled to capture a look at the web of the spider. These webs are much smaller and compact than the webs of some of the larger orbweaver spiders in our area, which is a good thing, because many of these webs seem to be built across paths and I often run into them face-first.

This little damselfly is called an Orange Bluet (Enallagma signatum). Yes, the name is confusing and seems to be a bit of an oxymoron. Most bluets have various patterns of blue and black on their bodies, but surprisingly there are also bluets that are patterned predominantly in red, orange, yellow, green or black. The male Orange Bluet adopted a seemingly confrontational pose and stared right at me as I prepared to photograph him last Thursday at Jackson Miles Abbott Wetland Refuge—maybe he felt the need to defend his territory.

I would have liked to have captured an eye-to-eye shot, but was afraid of scaring away the damselfly if I bent down closer to it, so took the shot from a downward angle. Although a substantial part of the Orange Bluet’s body is out of focus in this image, I think the shot worked out ok, owing largely to the fact that the damselfly’s eyes were in focus. The curve of the stalk on which it was perched was a nice bonus and added some visual interest to the shot.

I did not get a close enough look at it to identify its species, but a teneral damselfly decided to momentarily hitch a ride on my pant leg last Wednesday at Green Spring Gardens in Alexandria, VA. A teneral damselfly is one that has only recent emerged and is therefore pale and does not yet have its full adult coloration.

It turns out that a 180mm macro lens is less than optimal for a selflie, even of my leg—I could not get far enough away to include the whole damselfly in the frame. The only other alternative is for me to become a lot more flexible, which at my age does not seem very likely.

There are lots of different species of skipper butterflies in my area and it is hard for me to tell them apart. I spotted this beautiful little butterfly last Wednesday at Green Spring Gardens, just a few miles from where I live. I think that it is a Zabulon Skipper (Poanes zabulon), although it might possibly be the similar-looking Peck’s butterfly. I’d like to say that there is a scientific reason why I chose Zabulon over Peck’s, but it really is because I think that Zabulon is the cooler name of the two—I love the exotic sound of the word “Zabulon.”

I tried to get down to eye-level with the butterfly when I photographed it so that the background would fall away into a pleasant green blur and was largely successful. I like too that I was able to capture some of the green striations in the leaf on which the butterfly is perched and those little lines help to lead the viewer’s eyes to the butterfly.

This tiny Cabbage White butterfly (Pieris rapae) paused for only a moment on a pink flower, but I managed to get a shot of it on Wednesday at Green Spring Gardens. If you look closely, you can just make out the butterfly’s stunning green eyes.

The composition of this image is pretty simple, but I think it is effective. I would have liked to blur out the background a bit more, but even though it is cluttered, it is not distracting. I think that is because the pink and white are so bright and distinctive that they “pop” against the green background.

On Wednesday at Green Spring Gardens, a county-run historic garden just a few miles from my home, I got a really good look at this bee’s proboscis, the long, straw-like tongue that it uses to collect nectar. From my angle, it looked more like a deadly weapon. Yikes! As you can probably tell, I have switched to using my macro lens most of the time now that the warmer weather has caused more insects to reappear.

One of my friends on Facebook named this bee the “Gene Simmons” bee, because it reminded him of an iconic pose by the singer from the band KISS in which his extended tongue reached to the tip of his chin. It is hard to know if it is true, but according to urban legend, Simmons had his tongue insured for a million dollars during the 1970’s, when KISS was at its height of popularity. The popular rumor at the time that he had a cow’s tongue grafted onto his own, however, has been disproven.

I photographed this damselfly on last Wednesday at Occoquan Regional Park in Northern Virginia. The pattern of black and blue markings on the damselfly’s abdomen was unfamiliar to me. The closest I could come when comparing it with photos in my identification guide was a female Azure Bluet (Enallagma aspersum), but identification of bluet species can be tricky, since almost all of them are black and blue and you have to look really closely to distinguish one from another.

I posted the photo in a Facebook group dedicated to dragonflies and damselflies in Virginia and was a little shocked when one of the experts in the group confirmed my tentative identification. As far as I can recall, this is a new species for me, which makes this sighting even more special.

Yesterday I spotted my first Ebony Jewelwing damselfly (Calopteryx maculata) of the season while exploring at Occoquan Regional Park in Lorton, Virginia. As far as I know, this is the only damselfly in our area with completely dark wings, so it is a pretty easy species to identify.

Most of the time I spot Ebony Jewelwings in the shadowy vegetation along small streams, but this one was perched in the open. Perhaps it was enjoying the warmth of the spring sunshine.

I am not sure why the eyes of this damselfly appear to be red, because most of the time the eyes of male Ebony Jewelwings are darker. Perhaps the reddish coloration is a result of the angle of the light or maybe it is related to the age of the individual and will darken as he grows old.

I was delighted last Thursday to see quite a few Calico Pennant (Celithemis elisa) dragonflies during a visit to Occoquan Bay National Wildlife Refuge. The markings and wing patterns on this species are really striking, making this one of the most attractive species that I see during the dragonfly season.

Some of the Calico Pennants appeared to have newly emerged—when dragonflies initially break through the exoskeleton of their water-dwelling larvae selves, their wings are really shiny and fragile and their coloration is often pale. The dragonfly in the first photo appears to be in that stage of development, which is sometimes referred to as “teneral.” It you look closely at the place where the dragonfly is grasping the vegetation, you can see what is quite probably its discarded exoskeleton from which it had recently emerged.

The Calico Pennants in the second and third photo are females, as was the one in the first photo. The patterns on the wings of these more mature females are more distinct and their yellow coloration is somewhat brighter. How do I know that they are females? If you look closely at the ends of their abdomens (the “tails”) you can see the terminal appendages that indicate their gender.

Female Calico Pennants have yellow markings on their abdomens, but that is not a reliable indicator of their gender, because immature males have that same coloration. The dragonfly in the fourth photo, for example, is an immature male Calico Pennant. If you compare the tip of the abdomen of this dragonfly with the one in the third photo, you may be able to see that there are differences.

What does a mature male Calico Pennant look like? I managed to spot only a single mature male that day, but fortunately was able to capture a shot of it. As you can see in the final photo, adult male Calico Pennants have red marking on their abdomens and the veining on their wings is pinkish in color.

We are gradually transitioning to the summer dragonfly species and some of the early spring ones are starting to disappear. I’ll be keeping my eyes open for the “new” species, so don’t be surprised to see more dragonfly photos in the upcoming months.

I love to use my macro lenses. There is something almost magical about capturing details on tiny subjects, like this Fragile Forktail damselfly (Ischnura posita) that I spotted this past Monday alongside a pond in Prince William County, Virginia. Fragile Forktails are only about an inch (25 mm) in length, so I had to get pretty close to my subject to “fill the frame,” even with my 180mm macro lens.

One of the biggest challenges when I get this close to a subject is that my depth of field is really shallow, so I risk having a lot of my subject out of focus. In fact, in the majority of my photos of this damselfly, either the eyes or the tip of the abdomen is in focus, but not both. In this kind of situation, the “trick” to having the entire subject in focus is to position myself so that the sensor of my camera is parallel with the plane of the subject.

In this image, you can see that about the only things in focus are the damselfly and the edge of the leaf on which it was perched—the rest of the image is pleasingly blurred. This approach works pretty well with damselflies, which hold their wings above their bodies when perched, but does not work as well with dragonflies, which perch with outstretched wings. As a result, portions of the dragonflies in most of my photos are blurred, though I usually give top priority to keeping their eyes in focus.

As I was reviewing my photos of the past couple of weeks, I was a little surprised at the number of shots that I have taken of Blue Corporal (Ladona deplanata) dragonflies in wildly varying environments. Blue Corporals are an early-season species and won’t be around for too much longer, so I am happy to have had the opportunity to observe so many of them. Most of the time, Blue Corporals like to perch flat and, judging from the photos, it doesn’t seem to matter if there are rocks, vegetation, or even lily pads.

From the perspective of a naturalist, I like the way that the different photos give you a feel for the environments in which I found these dragonflies. As a photographer, I was also struck by the way that the colors and textures of the background interact with the subjects. Most of the backgrounds in these shots are somewhat cluttered, but I did my best to use framing and focusing techniques to keep the background from being too distracting.

If I had to make a choice, I would say that the first photo is my favorite of the Blue Corporal images. I love the juxtaposition of the dragonfly with the varied textures, shapes, and colors of the rocks. I also really like the way the background grows progressively more blurry towards the top of the image. Do you have a favorite?

The rain has stopped for now, but some raindrops remain, sparkling like tiny jewels this morning on the bearded irises in the garden of my neighbor and fellow photographer Cindy Dyer. I tried to get creative with the framing of the first shot, with a blurred iris in the background of an unopened bud.

In the second shot, I was so close to the bearded iris that you almost can’t tell that the primary subject is a flower—I love my macro lenses. There third and fourth shows show a couple more varieties of irises that are currently in bloom in Cindy’s garden, with lots more still to come.

Yesterday I went exploring in Accotink Bay Wildlife Refuge, a nature preserve on the grounds of Fort Belvoir, a nearby US Army installation. I did not see many dragonflies, but was happy to spot some Eastern Forktail (Ischnura verticalis) damselflies. These damselflies are quite small—about an inch (25 mm) in length—and have distinctive blue markings near the tips of their abdomens.

Many damselflies have combinations of black and blue on their bodies, so identification can often be difficult. Usually I start by looking at the body and deciding if it is primarily black, as was the case here, primarily blue, or somewhere in the middle. After that, I examine the shape of the markings at the tip of the abdomens and compare them with the pictures in my damselfly identification guide.

Somehow, though, I always have more problems with damselfly identification that I do with dragonfly identification. Fortunately I am part of several Facebook groups that have experts who can weigh in when I need help in identifying a particular damselfly.

I don’t know much about the courting behavior of Eastern Tailed-blue butterflies (Cupido comyntas), but the male at the bottom of the photo was actively pursuing a female when I photographed them on Wednesday in Prince William County. Eastern Tailed-blues are tiny butterflies, with a wingspan of about an inch (25 mm), so you have to look really closely to see the single narrow tail on each hind wing. When their wings are closed, Eastern Tailed-blues are mostly grayish0-white in color, so it was a real visual treat to be able to capture them with their wings open.

Most of the time fishing spiders have some of their legs in the water to sense the vibrations of potential prey, but the large Six-spotted Fishing Spider (Dolomedes triton) that I spotted last Friday in Prince William County was perched on a log at the edge of a small creek. When I posted the photo on Facebook, one of my friends noted that he often finds fishing spiders far from the water, including in his wood pile.

I do not know how large this spider was, but it looked huge to me. Perhaps that is because the spider had all of its legs fully extended, unlike some spiders whose legs are partially bent when they are in a web.

On Monday I was thrilled to photograph my first dragonfly of the year at Occoquan Bay National Wildlife Refuge, the location that I visit most frequently with my camera. The first prize goes to an immature male Blue Corporal dragonfly (Ladona deplanata)—males turn blue as they mature, but initially they have the same coloration as the females. Blue Corporals of both genders have two light-colored stripes on the front of their thoraxes, the traditional rank military insignia for corporals.

Later in the day I spotted a female Blue Corporal perched on some dry leaves, as shown in the second photo. Can you spot the differences between the dragonflies in the first and second photos? The male abdomen tends to be a bit thinner than the abdomen of the female. However, the biggest difference is in the terminal appendages, i.e. the specific parts at the very tip of their abdomens (their “tails”).

The following day I returned to the refuge and spotted another Blue Corporal perched in some vegetation—I think it is another immature male. Most of the time Blue Corporals like to perch on the ground, but this one looked like it had only recently emerged and may have been waiting for its wings to harden.

When dragonflies undergo their metamorphosis from water-dwelling nymphs to aerial acrobats, their wings are initially very clear and fragile and the creatures are very vulnerable, so I was careful not to disturb the dragonfly when I took a few photos. If you are interested to learn more, check out a 2016 blog posting  Metamorphosis of a dragonfly in which I documented the entire transformation process of a Common Sandragon dragonfly in a series of 15 photos. At the end of that series you will be able to see why I characterized the wings of a newly-emerged dragonfly as “fragile.”

Early spring wildflowers, like the Virginia Spring Beauty (Claytonia virginica), are an important source of food for a host of small bees and other insects. Many insects gather pollen from these flowers and in doing so help to pollinate the plants.

Some species of bees, though, lack  scopa (the pollen-collecting hairs) and do not collect pollen to feed their offspring. The genus Nomada, according to Wikipedia, is the largest genus of kleptoparasitic bees sometimes referred to as “cuckoo bees.” Kleptoparasitic bees are so named because they enter the nests of a host and lay eggs there, stealing resources that the host has already collected.

It is a little hard to see the body of the bee in the photo below, but if you look closely you can see its striped abdomen, which is wasp-like in appearance. I was not sure of the type of bee, so I posted it to BugGuide, a useful resource for insect identification, and one of the experts there identified the bee as belonging to the genus Nomada.

Have you ever looked closely at a dragonfly’s legs? A dragonfly has six legs that are attached in pairs to its thorax. The main parts of the leg are the upper leg or femur, the lower leg or tibia, and the foot or tarsus, which is made up of three segments and ends with a pair of claws. The legs are covered with spiky hairs and fulfill a variety of functions, including perching, catching and holding onto prey, and cleaning its mouth and eyes.

The first photo is a close-up view of a Uhler’s Sundragon (Helocordulia uhleri) that I spotted on 4 April near a creek in Prince William County, Virginia. You get a really good view of one of the middle legs of the dragonfly, including the way that it bends at two joints and the way the tiny claws are used to hold onto the perch. I can’t be sure, but I believe that the dragonfly may be using one of its front legs to wipe its large compound eye. If you click on the photo, you can see some of the thousands of ommatidia, the faceted optical units that allow a dragonfly to see in almost 360 degrees around itself.

In the second photo, you can see that the sets of legs are of different lengths. The back legs, which are the longest, are the ones that are most often used to catch and subdue prey. The front leg nearest us, does not seem to be used and the moment for perching and the “elbow” appears to be touching the eye. At first I thought that this was merely an awkward perch, but the more I look at the photo, the more I think that the dragonfly is cleaning its eye.

The final photo, which was actually the first of these photos that I took, shows the entire body of the Uhler’s Sundragon. The Uhler’s Sundragon is visually similar to the Selys’s Sundragon, the first dragonfly that I spotted this year, with the notable difference that the Uhler’s Sundragon has little orange patches at the base of its wings, as you can see in the photo, that are not present with the Selys’s Sundragon. If you look at the front legs, it appears to me that the dragonfly was using both of them initially for perching—its “elbow” does not appear to bent as it was in the middle photo.

This post was a little more “geeky” than usual, delving deeper into dragonfly anatomy than I usually do. I think it is fascinating to try to observe and understand the behavior that I see in my subjects and hope that you may also find these details to be somewhat interesting.

As I was exploring the edge of the same small pond where I photographed the newt featured in yesterday’s blog posting, I spotted my first damselfly of the season. Damselflies and dragonflies both belong to the order of flying insects known as Odonata. Damselflies tend to be smaller and slimmer that dragonflies and most damselflies hold their wings above their bodies when at rest, unlike dragonflies that perch with wings extended.

Identification of this damselfly was somewhat difficult for me. On the one hand, I saw the broken shoulder stripe that looks like an exclamation point, which suggests that this is a Fragile Forktail damselfly (Ischnura posita). On the other hand, my identification guide states that there is no blue at the tip of the abdomen (the “tail”) of the Fragile Forktail, making me think it might be an Eastern Forktail.

I posted the photo to a Facebook forum called Virginia Odonata and one of the experts there made the following comment, “This is quite an unusual Forktail. Easterns rarely have the split shoulder stripe, but I am still inclined toward Fragile even though the amount of blue on S9 is unusual.”  For your information, naturalists divide the abdomen of a dragonfly into ten segments and you start counting from the thorax area (the upper body), so S9 is the penultimate segment.

When it comes to identifying birds and insects, I have grown accustomed to living with some degree of uncertainty. Even experts will sometimes disagree, particularly if there is only a photo from a single angle, which was the case with this damselfly.

For me, the precision of my identification is not critically important—I can enjoy the beauty of this little damselfly without knowing its name. For the second day in a row, I am reminded of Shakespeare, who famously wrote in Romeo and Juliet, “What’s in a name? That which we call a rose, by any other name would smell as sweet.”

Yesterday was an unusually warm spring day, with temperatures soaring to 82 degrees (28 C). I suspected that I might find some early season dragonflies and I was right. Last week I saw my first dragonfly of 2023, but it does not really count for me, because I was not able to get a photograph of it.

My first “official” dragonfly of 2023 turned out to be an uncommon one, a Selys’s Sundragon (Helocordulia selysii). According to the Maryland Biodiversity Project, “Selys’s Sundragon is an uncommon, early-season corduliid which breeds in small streams in wooded areas through much of the southeast.” Corduliidae, also known as the emeralds, emerald dragonflies, or green-eyed skimmers, is the family of dragonflies to which the Selys’s Sundragons belong.

As far as I can recall, I have seen this species only twice in the past, both times in 2021. Check my 16 April 2021 blog posting entitled Selys’s Sundragon Dragonfly for details about my first encounter, including some photos that compare the Selys’s Sundragon with the very similar-looking Uhler’s Sundragon.

As many of you know, dragonflies are my favorite subjects to photograph during the warmer months. There is something almost magical about this beautiful aerial acrobats that inspires me. I love the challenge of spotting and photographing these tiny creatures—the Selys’s Sundragon in these photos, for example, is only about 1.7 inches (43 mm) in length.

During the summer, many common dragonfly species can be seen in a variety of habitats, but the early season dragonflies tend to be habitat specialists and have very brief flight season, often less than a month. For that reason, I usually try to go out with my camera as often as I can during the month of April.

Raindrops were glistening in the sunlight after an April shower on Saturday, enhancing the beauty of these red tulips in the garden of my dear friend and photography mentor Cindy Dyer.

One of my favorite movies when I was growing up was “The Sound of Music” and I can still remember the words of many of the songs from the movie. In one delightful scene, Julie Andrews tells the children that when she is unhappy, she tries to think of nice things and begins a song with the words, “raindrops on roses and whiskers on kittens…these are a few of my favorite things.”

Raindrops seem almost magical, whether they are on roses, on tulips, or on any other vegetation. If you are not familiar with the song “My Favorite Things,” here is a link to a YouTube clip of that wonderful scene from “The Sound of Music.”

At this time of the year I am drawn to any insects that I see flying about and I have found myself chasing after even small flies. There’s usually a period of readjustment as I switch from searching for subjects that are far away to looking for tiny subjects that are often only an arm’s length away from me. Most of the time I have to rely upon movement to spot these insects—only occasionally am I able to spot a perched insect.

As I noted in yesterday’s blog posting, I finally spotted my first two butterflies of the spring. I thought I had spotted a third butterfly last Wednesday at Occoquan Bay National Wildlife Refuge when this colorful little insect flew in front of me. I am pretty familiar with the butterflies in my area, but did not recognize this one.

After doing some research, I have concluded that this is probably a Grapevine Epimenis Moth (Psychomorpha epimenis). According to the Missouri Department of Conservation, “The grapevine epimenis flies during daytime and would seem too colorful to be a moth, but a moth it is. A member of the noctuid family, its many drab, grayish relatives include dagger, owlet, armyworm, cutworm, and earworm moths.”

Flowers are starting to bloom in the garden of my dear friend and fellow photographer Cindy Dyer. Yesterday I photographed several varieties of tulips and some cute little grape hyacinths.

As many of you know, I do not have my own garden. However, my photography mentor Cindy Dyer lives nearby and she has amazing gardens in her front, side, and back yards. She generally plants flowers that she knows are photogenic and I know that during the growing season that there will almost always be something to photograph.

Earlier this spring, I was able to photograph a few crocuses and a tiny red tulip, but now a whole lot more flowers are starting to appear. The multi-colored tulip in the first photo, I believe, is a variety known as the Lady Jane tulip (Tulipa clusiana var. ‘Lady Jane’). In the past, this tulip stood much taller—this one was growing close to the ground.

The red tulip in the second photo is a more traditional variety. I deliberately set my camera to have a shallow depth of field to blur out the background that at this time of the year is somewhat patchy and cluttered. As I processed the photos on my computer I noticed that I had inadvertently captured a shot of my first insect of the season, what Cindy likes to call a “bonus bug.” The weather yesterday was cloudy, so I did not have to worry about harsh shadows, which meant that the colors seemed especially vibrant and saturated.

The final photo shows a tiny grape hyacinth (g. Muscari), one of many that have popped up in Cindy’s garden. These colorful little flowers grow really close to the ground, so I was sprawled out a bit to get this low-angle shot that isolated the flower from the background.

Spring is almost here. This past weekend I spotted the first spring flowers—blooming in the garden of my friend and fellow photographer Cindy Dyer. Longtime readers of this blog are well aware that I am not a gardener, but often visit the Cindy’s garden during the flower season—Cindy deliberately plants flowers that are fun to photograph.

The first crocuses that I spotted were some purplish ones that in Cindy’s front garden. These are the type of crocuses that I encounter most frequently and I associate them with the arrival of spring. When I posted a photo of one on Facebook, Cindy alerted me to the fact that several yellow ones were blooming in her backyard garden.

I don’t recall ever having seem yellow crocuses before, so I was delighted to see them. I was really awkward trying to get a shot of them, so I resorted to getting a relatively close-up shot with my 60mm macro lens.

I have also noticed clusters of cheery yellow daffodils in bloom throughout my neighborhood. Our weather is still variable, but spring is on the way. On a side note, next Sunday we begin Daylight Savings Time, yet another sign of the changing seasons. If I am not mistaken, Europeans do not change their clocks until the last Sunday in March, which is 26 March in 2023.

As I was walking along on one of the trails at Occoquan Bay National Wildlife Refuge last Friday, I noticed a large spider coming in my direction at a pretty good clip. I gave the spider plenty of space, but managed to capture this image of what I believe is a Wolf Spider with my long telephoto lens.

Wolf spiders belong to the family Lycosidae and are among the most common spider species found around the world. According to an article entitled “Wolf Spider: Friend or Foe?” wolf spiders “are keen hunters that chase or pounce on prey like wolves rather than spin a web and wait for a meal. Unlike wolves hunting as packs, wolf spiders generally live and hunt alone. Hunting occurs both day and night.”

I was thrilled to spot this Blue-faced Meadowhawk dragonfly (Sympetrum ambiguum), one of my favorite species, this past Wednesday at Occoquan Bay National Wildlife Refuge. The dragonfly was cooperative and let me get pretty close with my Tamron 180mm macro lens and capture some of the amazing details of this colorful dragonfly, like its tiny feet and the little hairs on its legs.

I personally find the combination of the bright red body and the blue eyes to be stunningly irresistible and I look forward to spotting this species each autumn. If you click on either of the two images, you will be able to see some of the individual facets that make up the compound eyes. I have always wondered what it would be like to see the world through the eyes of a dragonfly.

I really like the description of a dragonfly’s sight that I found in a fascinating article by a writer called GrrlScientist that I encourage you to read. She wrote,

“Each compound eye is comprised of several thousand elements known as facets or ommatidia. These ommatidia contain light sensitive opsin proteins, thereby functioning as the visual sensing element in the compound eye. But unlike humans, day-flying dragonfly species have four or five different opsins, allowing them to see colors that are beyond human visual capabilities, such as ultraviolet (UV) light. Together, these thousands of ommatidia produce a mosaic of “pictures” but how this visual mosaic is integrated in the insect brain is still not known.”

I had to search hard to find this dragonfly and it was the only one of its species that I saw that day. At this time of the year few dragonflies are still flying. However, I am not ready to call it quits for the dragonfly season, though the end is drawing near.

Quite often when I am walking through grassy fields, the ground in front of me seems to explode with grasshoppers arcing through the air in all directions. Last week during a visit to Occoquan Bay National Wildlife Refuge, I managed to capture images of two of them.

I am not certain of the species of the formidable looking grasshopper in the first photo. When I looked through sources on line, however, it looked most like an American Bird Grasshopper (Schistocerca americana). Grasshoppers like this always make me think of medieval knights, suited up in protective armor.

The insect in the second image is almost certainly a katydid, and not a grasshopper—the extremely long antennae are often an easy identification feature. I love the brilliant green of the katydid’s body and its matching green eyes. There are lots of different kinds of katydids and I do not know to which species “my” katydid belongs.

We have had a lot of rainy weather recently and temperatures have noticeably dropped. Today’s forecast calls for intermittent rain and a high temperature of only 50 degrees (10 degrees C). I wonder if this cool, rainy period will mark the end of the season for some of the insects that I have been photographing during the past few months.

I think that the small spider in the foreground may be a male Black and Yellow garden spider (Argiope aurantia) and the larger one in the background a female of the same species. The body length of male Argiope aurantia spiders ranges from 0.20–0.35 inches (5–9 mm) and for females ranges from 0.75–1.10 inches (19–28 mm), according to Wikipedia.

A male Argiope spider communicates with a potential mate by plucking and vibrating the female’s web, according to the same Wikipedia article, which may explain what was happening when I captured this image on 13 September at Occoquan Bay National Wildlife Refuge.

I saw more than a dozen of the large female spiders at the wildlife refuge during my most recent visit there. Many of them had prey wrapped up in web material, stashed for future consumption. One of them, however, was busily consuming a ladybug, as shown in the second image below.

Black Saddlebags dragonflies (Tramea lacerata) are one of a dozen or so dragonfly species in North America that migrate. Not surprisingly they are strong fliers and most of the time when I see one, it is flying high overhead—they do not seem to perch very often.The dark patches on their hind wings, which someone thought resembled saddlebags, are so distinctive that it is pretty easy to identify a Black Saddlebags when I see one in the sky.

As I was exploring Occoquan Bay National Wildlife Refuge on Tuesday, I spotted a dragonfly as it zoomed by me and watched it land low in the vegetation. I moved forward as stealthily as I could and was delighted to see that the perching dragonfly was a Black Saddlebags. The background was quite cluttered, but I managed to find a clear visual path to the dragonfly and was delighted to capture this detailed image—I encourage you to click on the photo to see the beautiful markings on the abdomen and the distinctive “saddlebags.”

If you want to learn more about this particular species, I recommend an article from the University of Wisconsin at Milwaukee entitled “Black Saddlebags Dragonfly (Family Libellulidae).” Among other things, you will learn that for Black Saddlebags dragonflies, “Mating is brief if done aerially [the ultimate multitasking] and only slightly longer if the pair is perched.”

As I approached a patch of thistle in bloom on Tuesday, I was looking carefully to see if there were any butterflies feeding on the flowers. Suddenly I noticed a flash of bright red and realized immediately that it was a Hummingbird Clearwing Moth (Hemaris thysbe).

Hummingbird Clearwing moths, which actually do resemble hummingbirds as they dart among the flowers, hovering periodically to such nectar, are not exactly rare where I live, but I tend to see them only a few times a year. Fortunately I reacted quickly enough to capture this image, because the moth flew out of sight after it had finished feeding on this flower.

For shots like this, the wing position is really important and I was thrilled that I was able to capture the wings fully extended, which highlights the transparent portions of the wing responsible the common name of this species. The details of the moth and the thistle are pretty sharp and the background is blurred enough that it is not a distraction—I like this shot a lot.

During my recent visits to Jackson Miles Abbott Wetland Refuge, I have noticed the reappearance of Black and Yellow Garden Orbweaver Spiders (Argiope aurantia). During the late summer and early fall, these relatively large spiders can be seen in the vegetation surrounding the pond and in the adjacent fields.

One of the coolest things about this spider is the distinctive zig-zag pattern, known technically as a stabilimentum that the spider uses for the central part of its web. According to Wikipedia, the purpose of the zig-zags is disputed. “It is possible that it acts as camouflage for the spider lurking in the web’s center, but it may also attract insect prey, or even warn birds of the presence of the otherwise difficult-to-see web.”
