Although some folks find spiders to be creepy, I look at them as wonderfully creative architects and artists and I was thrilled to capture this image of one in its web that I spotted early yesterday morning at Occoquan Bay National Wildlife Refuge. I have found that early morning is the best time to get shots of spider webs and they tend to show up best in shots that are backlit, which is to say that light is shining from the front. In this case I tried to frame the shot carefully for maximum effect and did not have to crop the image at all.

The loud cries of an osprey (Pandion haliaetus) echoed though the early morning air yesterday at Occoquan Bay National Wildlife Refuge. I was never able to figure out what was bothering the clearly unhappy osprey, but did manage to capture this image of the screaming bird just before it flew away.

I was thrilled this morning at Occoquan Bay National Wildlife Refuge to see that there are still quite a few Monarch butterflies (Danaus plexippus) in our area, including this beauty that I was able to photograph as it was feeding on a thistle plant.

At first I thought it was love, but looking closer I realized that Tina Turner was right—what’s love got to do with it. Both the predator and the prey in what appears to be an act of cannibalism look to be Big Bluet damselflies (Enallagma durum), which I spotted this past Sunday at Occoquan Bay National Wildlife Refuge.

The pale coloration of the victim suggests to me that it is newly-emerged, a phase referred to as “teneral.” At this stage of development, dragonflies and damselflies are relatively immobile as their bodies and wings are transforming and are particularly vulnerable.

As the seasons change, some dragonflies begin to disappear, but happily some new ones appear, like this spectacular female Blue-faced Meadowhawk (Sympetrum ambiguum) that I spotted this past Monday at Huntley Meadows Park.

One of the really cool things about this species is that there are two different color variants of the females. Most of the females (and young males) are brown in color and are sometimes referred to as heteromorphs, while a smaller number of females, like the one in the photo, have a bright red color matching that of mature males and are sometimes referred to as andromorphs. This is roughly parallel to the Eastern Tiger Swallowtail butterfly, which has two different varieties of female, a yellow morph that matches the males and a black morph.

What is a Fine-lined Emerald? It may sound like some kind of exotic jewel, but it is actually a relatively rare dragonfly that is found in coastal plains areas. I don’t recall having heard of this species until several weeks ago, when fellow dragonfly enthusiast Walter Sanford alerted me to keep an eye out for them when visiting nearby Occoquan Bay National Wildlife Refuge.

I met Walter this past Sunday at the wildlife refuge and we began out search for the elusive Fine-lined Emerald (Somatochlora filosa). This species tends to hang vertically from bare branches at about eye level, so we walked slowly past the never-ending vegetation, hoping that we would spot one. I honestly was not optimistic that we would be successful and was shocked to almost stumble upon one only about four feet from me. I had two big problems. First of all, I was using my Tamron 150-600mm lens that has a minimum focusing distance of almost 9 feet (2.7 meters), so I had to back up. Secondly, in my excitement, I was unable to clearly explain to Walter exactly where the dragonfly was perched. In the end, the dragonfly flew away before either of us was able to get a shot.

Eventually we were able to track that dragonfly and several other Fine-lined Emeralds and to capture some images of these beautiful creatures. Walter and I agreed that we would both do blog postings with some of our shots today to give readers an idea of how two photographers standing almost side by side can come up with very different photos of the same subject. We have done this type of companion pieces and it had always been interesting to compare results. Some of the differences can be attributed to the very different gear that we are using and some are caused by our different backgrounds and approaches.

Once I publish this posting, I will finally take a look at Walter’s posting and update this posting with a link to it.

UPDATE:  Here is the linkas promised, to Walter’s post, in which he shares some scientific observations and some wonderful photos.

This spectacular Black Swallowtail butterfly (Papilio polyxenes) spread its wings wide and seemed to be posing for fellow wildlife enthusiast Walter Sanford and for me as we explored Occoquan Bay National Wildlife Refuge this past weekend. We have a number of different dark-colored swallowtail butterflies in our region, including the black morph of the female Eastern Tiger Swallowtail, the Pipevine Swallowtail, and the Spicebush Swallowtail, but this is the only place that I have encountered the Black Swallowtail.

Whenever I photograph a swallowtail that is black, I will usually refer to a very helpful blog posting by Louisiana Naturalist that compares some of the identification features of the four different dark swallowtails.

When I spotted this praying mantis today at Huntley Meadows Park, I couldn’t help but think that it had chosen an appropriate pose to remember those who died and countless others whose live were forever changed by the tragic events of 9/11.

When a Black and Yellow Garden Spider (Argiope aurantia) traps a prey in its web, it often moves so quickly to wrap it up completely that it is difficult to identify the prey. That was not the case with the damselfly that I spotted yesterday at Occoquan Bay National Wildlife Refuge as it was being encased in a silken shroud.

The damselfly looks to be a bluet damselfly and if pressed, I’d guess that it might be a Familiar Bluet (Enallagma civile) or possibly a Big Bluet (Enallagma durum). The spider seems to be experiencing the same kind of problem that I encounter when I am trying to wrap an awkwardly-shaped present at Christmas time—it is hard to be neat and tidy, the process uses up lots of wrapping material, and the package always end up irregularly shaped and easy to identify.

When I first saw this dragonfly land yesterday at Occoquan Bay National Wildlife Refuge, I had no idea what it was. Zooming in, I was shocked to see that it was a Wandering Glider (Pantala flavescens), a migratory species that almost never perches.

The Wandering Glider is considered to be the most widespread dragonfly in the world, found on every continent except Antarctica. According to odonatacentral.com, “It is a strong flier that is regularly encountered by ocean freighters and a well-known migratory species. Because of its ability to drift with the wind, feeding on aerial plankton, until it finally encounters a rain pool in which it breeds, it has been called “…the world’s most evolved dragonfly.” ”

After I got the initial shots of the dragonfly on two different perches, I decided to follow the dragonfly and wait for it to perch again. It wandered about through the air over my head for an extended period of time and never again came down to land. The last photo gives you an idea of my view during that period of waiting—note the long wings that help it to fly such long distances.

I was really happy to spot a couple of male Calico Pennant dragonflies (Celithemis elisa) during a visit today to Occoquan Bay National Wildlife Refuge in Woodbridge, Virginia. The weather was pretty cool when I set out early this morning, about 56 degrees (13 degrees C), so I was not certain that I would be able to find many dragonflies. Fortunately for me it warmed up a bit and a few dragonflies appeared.

The bright red color of this dragonfly helps a little in finding them, but Calico Pennants are pretty small and it is easy to lose them in the vegetation. I shot the first two shots with my Canon 50D DSLR and Tamron 150-600mm telephoto zoom lens and the third one with my Canon SX50 super zoom camera. The poses are not identical, but I think that you can see how much shallower the depth of field is when using the DSLR than the point-and-and-shoot—I think it is related to the difference in the size of the sensors in the cameras.

Do you have a favorite insect? This is such a strange question that most folks would not have an immediate answer and would have to stop and think a bit before responding. The quickest responses would undoubtedly come from those who simply do not like insects at all. The most common positive answer, I suspect, might well be a Monarch Butterfly.

Many readers know that I see lots of beautiful dragonflies and butterflies, but my favorite insect is almost certainly the Handsome Meadow Katydid (Orchelimum pulchellum), like this one that I photographed on Monday at Occoquan Bay National Wildlife Refuge. I remember my sense of awe and amazement the first time that I spotted one—I couldn’t believe my own eyes, because the combination of colors seemed so bright and almost unreal. When I initially posted a photo of the Handsome Meadow Katydid, one of my friends thought that I had added the colors in Photoshop.

To this day, I never fail to marvel at a Handsome Meadow Katydid’s spectacular rainbow colors and incredible blue eyes and am always thrilled to discover again their amazing beauty when I am fortunate enough to find one.

The biological clocks of some species seem to be ticking as the summer winds down, compelling them into frantically mating sessions, like this pair of Halloween Pennant dragonflies (Celithemis eponina) that I spotted this past weekend at Lilypons Water Gardens in Adamstown, Maryland. The challenge in photographing this type of activity is to present it in a way that is artistic rather than purely sexual.

Whenever I see bees buzzing around flowers, I keep an eye out for hummingbird moths. For some unknown reason, I have seen more of these colorful moths this summer than in past years.

Although you could argue about whether or not thistles are flowers, my vigilance was rewarded when I spotted this beautiful Hummingbird Clearwing Moth (Hemaris thysbe) feeding on this thistle bloom on Monday at Occoquan Bay National Wildlife Refuge.

As summer begins to wind down for those of us in the Northern Hemisphere, some of the dragonfly species in our area are starting to disappear. Fortunately, though, some new species appear late in the season to take their places, like this Russet-tipped Clubtail dragonfly (Stylurus plagiatus) that I spotted yesterday at Occoquan Bay National Wildlife Refuge in Woodbridge, Virginia.

Unlike many of the dragonflies that I see regularly that seem to prefer pole-like perches or perch flat on the ground, Russet-tipped Clubtails like to hang from the leaves of vegetation either at an angle, as this one is doing, or vertically. I was pretty excited to find this dragonfly, because I have seen a member of this species only once before, last year at a different location, Jackson Miles Abbott Wetland Refuge.

“Beautiful Spider”—I know that some people would consider that an oxymoron, a contradiction in terms. I, however, am fascinated with spiders and photographed this Black and Yellow Garden Spider (Argiope aurantia) at Jackson Miles Abbott Wetland Refuge as carefully as if I were doing a beauty shot in a photo studio. The spider had constructed her web on some vegetation overhanging a small pond, which is why  I was able to get such an uncluttered gray background.

Argiope aurantia

Earlier this month I captured an image of a spider of the same species while exploring Occoquan Bay National Wildlife Refuge—this seems to be the prime season for these spiders, which I have seen at multiple locations. This image shows well the amazing reach of the spider’s amazingly long legs and, as was the case in the first image, shows the ziz-zag portion of the web that is associated with this species.

When it comes to dragonflies, what catches your eye? Is it their bright colors or their acrobatic flying skills? When it comes to male Twelve-spotted Skimmers (Libellula pulchella), it is definitely the bold brown-and-white pattern on their wings that irresistibly attracts me. I somehow feel compelled to chase after one whenever I spot it.

Yesterday I made a brief trip to Lilypons Water Gardens in Adamstown, Maryland. This sprawling facility has over 150 acres of amazing ponds and water gardens with fantastic displays of water lilies, which are for sale. (I’ll feature some of the different colored water lilies in an upcoming post.) Although I saw a lot of dragonflies there, I saw only a few Twelve-spotted Skimmers.

Most of them were remarkably elusive, but one finally perched on some vegetation overhanging the water. The bank was fairly steep, so there was no way that I could get a side shot or a head-on shot, which is one of my favorite shots of a dragonfly. What was I going to do?

Then it dawned on me that I had a perfect view of the magnificent wing patterns as I looked straight down the body of the dragonfly, facing in the same direction that he was facing. Boldly I decided to commit what is normally a cardinal sin for a photographer—I intentionally chose not to focus on the subject’s eyes. Lightning did not strike me as I pressed the shutter and I captured an almost abstract portrait of the dragonfly. For me, there is a real beauty in the simplicity and minimalism of this image.

In case you get confused about counting the twelve spots, you’re supposed to count only the brown spots. According to Wikipedia, though,some folks prefer to count the white spots and therefore call this dragonfly a “Ten-spot Skimmer.”

The bright blue color of a juvenile skink’s tail is so startling and whimsical that I never fail to smile whenever I see one. When I first spotted this Common Five-lined Skink (Plestiodon fasciatus), it was basking in the sun on top of a concrete fishing platform at Jackson Miles Abbott Wetland Refuge. As I approach, it scurried under the platform and I stopped and waited. Eventually the skink poked its head out and cautiously crawled forward and I was able to capture this image.

Generally I prefer a more natural backdrop for my shots of insects and amphibians, but in this case I really like the varied colors and textures of the man-made materials. I also like the angular lines that contrast nicely with the curves of the skink’s body. Finally the neutral colors of the image help to draw the viewer’s eyes to the beautiful blue tail.

As the days of summer gradually wind down, I can’t help but notice a significant amount of wear and tear on the bodies and especially the wings of some of the dragonflies and butterflies that I see. Clearly it has been a long, tough season for some of them. Despite its tattered wings, this male Great Blue Skimmer dragonfly (Libellula vibrans) that I spotted on Monday at Huntley Meadows Park seemed to have no trouble flying, though I suspect that his days are numbered.

I hope that all of you have managed to survive this season well and that your “summer wear” refers to your clothes and not to the condition of your body.

Different species of dragonflies fly in different ways. Some soar high in the air and some cruise just above the surface of the water. A dragonfly’s wings allow it to perform all kinds of aerial acrobatics that are entrancing to observe. Given their size and speed, it’s a significant challenge to try to capture them in flight, though frequent readers of this blog know that I will sometimes spend extended periods of time trying to meet that challenge.

During a recent trip to Occoquan Bay National Wildlife Refuge, I noticed a dragonfly flying above my head. Its flight reminded me of eagles and hawks that I have seen gliding effortlessly on thermal updrafts. I couldn’t make out the flight pattern that it was following, but it repeatedly flew over me. Each time that it returned, I would point my camera almost straight up and eventually I was able to capture this shot of an easy-to-identify Black Saddlebags dragonfly (Tramea lacerata)—the pattern of black blotches on the wings are very distinctive.

Later that same day I spotted a dragonfly making repeated patrols above the water. The dragonfly never seemed to rest or to perch, so I tried and tried to capture some shots of it as it zoomed on by me. Most of my shots were out of focus, but I like the one below. The choppy water in the background reminds me of the clouds that I will sometimes see when I look out of the window of an aircraft that has reached its cruising altitude. In my mind’s eye, I can imagine this dragonfly flying high in the sky, peacefully soaring above the clouds and the turbulence below it.

A clump of what I think is Swamp Milkweed (Asclepias incarnataseemed irresistible to a trio of Great Spangled Fritillary butterflies (Speyeria cybele) on Monday at Huntley Meadows Park. For a brief moment they coexisted peacefully, until one of them encroached into the territory of another and they all began to jostle each other for the prime spots.

I quickly snapped off a series of photos before the butterflies flew away. As is the case with almost any group, it was almost impossible to capture an image in which all of the subjects were more or less facing the camera and had interesting poses. It was roughly equivalent to trying to photograph a group of wiggly little children—single subjects seem easy by comparison.

When is a cluttered background so distracting that it draws attention away from the primary subject? When I have the luxury of time, I will normally attempt to compose my shots so that the background fades into the background as a creamy blur. As a wildlife photographer, though, I am often photographing live subjects that are likely to flee as soon as they become aware of my presence. Frequently I barely have time to bring the camera up to my eye and am forced to react rapidly and instinctively—I just don’t have time to think about the background.

Yesterday as I was walking along the Mount Vernon Trail in Alexandria, Virginia parallel to the Potomac River, I spotted a bird at the very top of a distant tree. Earlier in the day I had seen an osprey in a similar position, so I initially assumed it was another osprey. I had just zoomed in on the bird when it exploded out of the tree into the air. From the way that it was flying, I realized that it was probably an eagle or a hawk. I tracked the bird, which I believe is a Red-tailed Hawk (Buteo jamaicensis) as it flew behind some trees and eventually into the clear blue skies.

Here are my three favorite shots of the encounter. Two of them are cluttered and one has a plain blue background. Which one do you like most? I am not bothered by the branches in the first two shots and like the way that they help to give a sense of context to the action that is depicted. The third shot shows some of the wonderful details of the beautiful hawk, but it seems a bit more sterile to me. (For the record, the first shot is probably my favorite of the three images.)

Are cluttered backgrounds ok? Like so many factors in photography, the correct response appears to be that it depends on the specific circumstances.

The beautiful Monarch Butterfly (Danaus plexippus) is often featured in conservation efforts that focus on its dwindling numbers and shrinking habitat. It was therefore a little disconcerting to stumble upon a Monarch that had been ensnared in the web of a Black and Yellow Garden Spider (Argiope aurantia) during a visit this past weekend to Occoquan Bay National Wildlife Refuge.

I have no idea how long the butterfly had been in the web, but it appeared to be totally immobilized. Spiders like this one, known also as Yellow Garden Spiders or Writing Spiders, kill their prey by injecting venom and often wrap them up in web material for later consumption.

I considered cropping this image to focus more attention on the spider and the butterfly, but ultimately decided that I liked the context provided by the elements of the spider’s web and the murky, out-of-focus background.

One of the coolest looking butterflies in our area is the Zebra Swallowtail butterfly (Eurytides marcellus). In addition to having beautiful coloration, it has amazingly long “tails” that flutter when it is in flight. It is not a species that I see very often, so I will spend a lot of time chasing after one when I spot it, hoping, often in vain, that it will perch long enough for me to get a shot.

This Zebra Swallowtail, which I chased this past Friday at Occoquan Bay National Wildlife Refuge, was reasonably cooperative, though it refused to open its wings to give me a view of its entire wingspan.

Predator or prey? Dragonflies are fearsome predators, but they can also become prey—it’s the whole circle of life cycle in the natural world.

This past Friday as I was walking around Occoquan Bay National Wildlife Refuge, I spotted the twisted body of a dragonfly suspended in the air against a backdrop of the sky. Instinctively I knew that there must be a spider web there, although it was not initially visible. The wing pattern of the dragonfly made it easy to identify as a Common Whitetail (Plathemis lydia).

As I got closer, I realized that a large spider was holding onto the body of the dragonfly. I am not totally certain of the spider identification, but it looks to me like it is a Spotted Orbweaver (Neoscona crucifera). Often when I approach a spider, it will scurry to the edge of its web, but this spider defiantly stayed in place—it looked like it was determined not to give up its prey.

As many readers know, I really like dragonflies, but spiders have to eat too. Undoubtedly this scenario plays out multiple times each day, but it is still a little unsettling to see it face-to-face.

Dragonflies have to eat too, but I was a little shocked when I stumbled upon this Needham’s Skimmer dragonfly (Libellula needhami) munching on a ladybug or two yesterday at Occoquan Bay National Wildlife Refuge in Woodbridge, Virginia. Although I know that dragonflies are fearsome predators, I guess that I am not used to thinking of ladybugs as prey—they are usually depicted as cute, which is why they are seen so often on children’s clothing and furnishings.

I spent a considerable amount of time one morning earlier this month at Huntley Meadows Park trying to get some shots of this skittish female Belted Kingfisher (Megaceryle alcyon). It was almost impossible to get really close, so I had to rely on my long telephoto zoom lens.

Although I tend to associate Monarch butterflies (Danaus plexippus) with milkweed, this Monarch was hungrily feeding on Queen Anne’s lace (Daucus carota) this past weekend at Huntley Meadows Park. I am not sure why, but I have seen significantly more Monarch butterflies this summer than in the past few years.

As I was exploring at Huntley Meadows Park this past weekend, I was thrilled to stumble upon this beautiful Painted Lady butterfly (Vanessa cardui), a species that I have not seen in several years. In the field, I couldn’t remember the differences between a Painted Lady and the similar-looking American Lady. Fortunately, there are plenty of resources on-line, including this helpful comparison page on bugguide.net that shows the differences between the two types. On the basis of the pattern of the eye spots, I concluded that this is almost certainly a Painted Lady.

Several years ago, when I first started getting serious about photography, I probably would have called the insect in the photo a bee. My choices back then were simple—a black and yellow insect was either a bee or a yellowjacket. Now that I know a whole lot more about insects, I can readily identify the insect as a hoverfly (also referred to as flower fly) from the Syrphidae family.

When I spotted the hoverfly yesterday, I was struck by the way that its colors matched almost perfect those of the black-eyed Susans (Rudbeckia hirta) that were growing in abundance at Jackson Miles Abbott Wetland Refuge.

When I first encountered two insects this past weekend at Huntley Meadows Park, I thought they were mating. Looking a little closer, I realized it was a robber fly and its prey, which, after some research, I conclude is probably a Striped Horse Fly (Tabanus lineola). In addition to its unusual eyes, check out the sharp mouth parts of the horse fly that are used, I believe, for biting. Ouch!

There is a whole family of robber flies, known as Asilidae, of varying sizes and shapes, including the Red-footed Cannibalfly that I have featured several times recently. This robber fly was considerably smaller than a Red-footed Cannibalfly, but has many of the same general characteristics. They both grasp their prey with their long legs and inject it with saliva that paralyzes the victim. The saliva eventually liquifies the insides of the prey and the robber fly sucks out the liquified material through its proboscis. I think that the robber fly in the photo was in the middle of that process when I spotted it.
