Have you ever found yourself in a thorny predicament? Last weekend, I came upon this female Spangled Skimmer dragonfly (Libellula cyanea) that had literally placed herself in such a situation.

Fortunately, dragonflies are so small, lightweight, and agile that she was able to place herself in between the thorns, out of harm’s way. If you look closely at her wings in the second image, however, you’ll see that they are tattered, suggesting that it’s been a tough season for her, probably as a result of predators, including overly aggressive male dragonflies.

As I search in vain for larger, colorful butterflies, I continue to be amazed by the beauty of the smaller ones, like this Clouded Sulphur butterfly (Colias philodice) that I observed last week at Green Spring Gardens in Alexandria, Virginia.

Generally I like my closest shots the best when I am shooting with my macro lens, but in this case, I think I prefer the first shot below, that I took from a bit farther back. I like the way in which you can see the shadowy representations in the background of the stalks of the same kind of floweras the one one which the butterfly is feeding.

When I started shooting regularly two years ago, I followed the lead of my mentor, Cindy Dyer, who specializes in flower photography, and spent a lot of time in gardens. (She photographs a wide range of  subjects, though, and I encourage readers to click on her name and check out the photos on her blog from a recent trip to Iceland.)

Last weekend I went back to my roots and visited a local garden with Cindy, where I spent some time with flowers and was only occasionally distracted by insects. Cindy helped me identify a toad lily and some zinnias, but we think the yellow flower is some kind of rudbeckia.

As I was shooting, I was particularly fascinated by the structure and patterns of the petals and by the amazing colors. The colors proved to be a challenge to render correctly and I am not entirely certain that I got the pinkish color of the zinnias true to life.

Two years ago in a posting, I confessed to being obsessed with photographing Red milkweed beetles (Tetraopes tetraophthalmus). Inexorably I kept finding myself being drawn back to these bright red beetles.

I thought I had outgrown my obsession, until I encountered several of my little red friend this past weekend at Green Spring Gardens. I immediately reverted to my old behavior and began to stalk them like a paparazzo, trying to get a good shot or any shot at all.

My obsession continues.

Whenever I have my macro lens on my camera I seem to be irresistibly drawn to bees, like bees to honey. No matter what else I am shooting during the summer, I always seem to have some images of bees interspersed among my other photos. Here are some of my recent favorite bee shots.

Photographing any dragonfly in flight is a real challenge, but this past weekend I spent time chasing after some of the smallest ones, the Eastern Amberwing dragonflies (Perithemis tenera). According to Bugguide, these dragonflies are typically 21-24mm in length, which is less than one inch, with a wingspan of maybe two inches or so.

amb2_fly_blog

There were lots of male Eastern Amberwings buzzing around the edges of a small pond at Green Spring Gardens, one of the local gardens that I like to visit. They were within range of the 180mm macro lens that I was using, but focusing and tracking were my biggest problems. The dragonflies did tend to hover a bit, which helped a little, but it was tough to get them in focus when focusing manually and almost impossible to do so with auto-focus.

I took a lot of shots and was happy that I managed to get some in decent focus, though I did have to crop the images. As I was preparing this posting, I noticed that I spent some time a year ago attempting to photograph the same dragonfly species. I think the results this year are marginally better, but you can make your own call by clicking on this link to the posting from July 2013.

A dragonfly perching on a heron? In real life it’s highly unlikely that you would see such a thing, but a male Blue Dasher dragonfly (Pachydiplax longipennis) decided that the metal silhouette of a Great Blue Heron (Ardea herodias) in a pond at Green Spring Gardens made a good spot to rest.

Small skipper butterflies don’t stand out as much as their larger, more colorful brethren, but they have an understated beauty that I find striking. It’s a daunting challenge, however, to identify them.

According to Wikipedia, there are more than 3500 recognized species of skippers worldwide, so I don’t feel too bad that my identification skills are weak in this area. As I looked through images on-line, I came across one identified as a Little Glassywing (Pompeius verna) that looks a bit like the one that I photographed, though my confidence level in this identification is pretty low.

I am confident, however, that I like the image I captured of the little skipper. There is a pretty good amount of detail, the background is blurred, and the leaves on which the butterfly is perched makes for an interesting pose.

UPDATE: A butterfly expert has definitively identified this as a female Sachem (Atalopedes campestris). Thanks to Joe Schelling and Jim Brock for their assistance in identifying this little skipper.

In the shade of the flowering lotus plants, these two Eastern Pondhawk dragonflies (Erythemis simplicicollis) found a few moments for some summer lovin’. Summer lovin’, it happened so fast.

Even before they have bloomed, the buds of the Lotus flower (Nelumbo nucifera) can be spectacularly beautiful, like this one I photographed this past Monday at Green Spring Gardens, just a few miles from where I live in Northern Virginia.

Although I don’t live in Ohio, nicknamed “The Buckeye State,” I think that I can claim that Virginia also is a Buckeye state, because we are a home to the uncommonly beautiful Common Buckeye butterfly (Junonia coenia).

Common Buckeye butterfly

I have seen few colorful butterflies so far this summer, besides the Great Spangled Fritillary butterflies that I featured in a posting in June. Where are all the Monarchs and Eastern Swallowtails? I don’t know if they were affected by the polar vortex of this past winter or if I am merely looking for them in all the wrong places, but their numbers seem to be unusually low this summer.

I was therefore thrilled this past Monday, when I caught sight of this Common Buckeye. Its coloration is so distinctive that I immediately recognized it and chased after it a bit. Fortunately I was able to capture several images of this beautiful creature before it flew out of sight.

Looking at these images, I am happy to proclaim that I live in a Buckeye state.

I simply love the exquisite beauty of lotus flowers.  A sense of tranquility seems to fill me during those moments when I am able to drink in their beauty, especially when I am alone.

I took these shots in mid-morning at Green Spring Gardens, a county-run facility that has two small, man-made ponds, in addition to the extensive gardens. The ponds are one of my favorite places to shoot when my time is limited and in the past I have captured some wonderful images of turtles, frogs, birds, and dragonflies. What makes the ponds really special for me, though, is that there are water lilies and lotuses at this time of the year.

I am experimenting with presenting my photos in the Gallery format. If you click on any one of the images, you can scroll through each of them in succession in full size. Let me know if  you think it works better than presenting each shot individually.

lotus3_blogWhen the lotus flowers are completely open, it is a real joy to be able to look inside the flower and glimpse the cylindrical seed pod, which contrasts wonderfully with the delicate pink petals in color as well as texture. I took these shots in the middle of the morning, which is usually a less than optimal time of day for lighting. In this case, though, the light, which was often coming from behind the flowers, helped to highlight the flowers and created some interesting shadows.

Some amazingly beautiful water lilies were in bloom at a local garden yesterday morning and seemed to be glowing from within.

Green Spring Gardens is a county-run historic garden just a few miles from where I live. I used to shoot there really often, but have been spending more time instead at my local marshland park. A couple of recent postings by Rob Paine on his blog I see beauty all around reminded me of the beauty of this garden and I spent several hours there yesterday, getting shots, primarily of the water lilies, lotus flowers, and dragonflies.

This image is a sneak preview of yesterday’s shoot, with more to follow in the near future.

It may sound like a new summer beverage sensation, but the title is meant to be literal. I encountered this tiny Eastern Amberwing dragonfly (Perithemis tenera) sunning itself on a rock in a small, muddy creek in the back area of my local marshland park.

It was a bit unusual for me to see a dragonfly on a rock (usually they perch on vegetation or on the ground) and I think the texture of the rock adds visual interest to the shot without being distracting the eye. I was pleased to capture so much beautiful detail of this cool little dragonfly and was particularly happy to see how well the amber wings turned out.

How many views does your average post get? WordPress has a strange way of measuring “views” and “likes” that I haven’t quite been able to figure out, but I consider a posting to be successful if it gets about 30 views. A really popular posting might get 50 views.

As I close out my retrospective look this week at my first two years of blogging, I thought I would share again the posting that, statistically speaking, is by far the most popular. Out of the 1200+ postings that I have done, only seven have over a hundred views and the second most viewed posting has 138 views. The posting below has had 371 views.

Don’t get me wrong—I like these photos of the fuzzy white caterpillar, but I certainly don’t consider them to be my best or my favorite images. How did I get so many views?

Not long ago, Leanne Cole, one of my favorite bloggers did a couple of postings on Search Engine Optimization (SEO) that included a discussion of some techniques to make your photos and postings more visible when people do searches with Google and other search tools. I think I may have inadvertently used some of these approaches with the caterpillar posting, because the majority of the views seem to have come from people who found the images as the result of a search, and not from readers of my blog.

I don’t put a lot of faith in statistics and they don’t count for much in my personal estimation of the success of a posting. However, I am by nature a very curious person, so I can’t completely ignore them, even if they seem a little crazy.

Complete text of my 3 August 2013 “Fuzzy white caterpillar” posting:

It’s hard enough to identify moths and butterflies when they are fully grown—it seems almost impossible to do so when they are caterpillars, like this fuzzy white caterpillar that I encountered today at my local marshland park.

The caterpillar had so much long hair that it was hard to see the actual body, which might have been quite small for all I could tell. It was crawling around in the cattails on a day that featured intermittent rain. If you look closely at the first shot, you can see little water drops near what I think is the area of the head.

The second shot may look like it was done with flash, but the darker background was caused merely by changing the settings on my camera and deliberately overexposing the image.

Which of your images are unusual or distinctive enough that you genuinely feel like they are “once in a lifetime” photos?

Of course, all photos are unique captures of a subject at a particular moment. As the ancient Greek philosopher Heraclitus is reported to have said, “No man ever steps in the same river twice.”

Somehow, though, it seems like we could capture similar images in many cases if we returned to the same locations under similar conditions and were patient and persistent enough.

As I celebrate my two year blog anniversary this week, I’ve been doing a few retrospective re-postings of favorite posts from the earliest days and am continuing in that vein today with some photos of a North American Beaver (Castor canadensis) breaking through the ice of a beaver pond from below on a winter day early in 2013.

A lot of things had to work together perfectly for me to get these images and it’s hard to imagine that confluence of factors ever happening again for me. The photos and the accompanying prose help to document that very special moment.

Besides the uniqueness of that moment, there is something particularly enjoyable about posting icy winter photos as we continue to suffer through a seemingly endless cycle of hot, humid summer weather. I hope that you feel as refreshed as I do when viewing these images.

Complete text of original posting Breaking through the ice from below on 30 January 2013:

The beaver had disappeared from the small open water area of the ice-covered beaver pond.  Wondering if he would resurface, I stood in silent readiness with my camera still in my hand.

My eyes were focused on one area of the pond, but my ears detected a sound emanating from another location near the edge of the pond. Somehow I knew instantly what was about to happen—the beaver was about to achieve a breakthrough. The light had faded a bit and I couldn’t see well enough to focus perfectly, but I aimed at the source of the sound and got this shot of the beaver poking his head through a newly-created hole in the ice. From this perspective, it looks like the beaver is pretty small.

breakthrough1_blog

As I watched, the beaver placed his front paws on the ice, which appeared to be able to support his weight, and gradually pulled his body out of the water. Naturally, the small hole became a lot bigger as his large body came increasingly into view.

breakthrough4_blogbreakthrough2_blogAfter the beaver was completely out of the water, he bent down over the opening that he had just created. Perhaps he was trying to decide if he needed to enlarge it further or was trying to free a tasty-looking stick from the ice. It almost looks to me, though, that he is peering into the water, wondering if one of his fellow beavers is going to be popping up to join him.

breakthrough3_blog

The beaver did not linger long at the new location. After a few seconds on the “outside,” he dove back into the icy waters of the pond.

There are few moments in life that are truly “once-in-a-lifetime” experiences, ones that would be impossible to replicate, but I have the sense that this was one of them. So many things had to work together to make these photos happen—the timing, the location, and the ice, to name a few.

It is supposed to get up to 70 degrees (21 degrees C) today and the ice will almost certainly be gone by the time I am able to return to the marsh this weekend. Perhaps I will get to observe the beavers eating or working or playing or maybe they will remain in the lodge. In either case, I can be happy, knowing that we shared a really special moment together.

When I am walking through the woods adjacent to the marsh, I often see small brown butterflies flitting about, but it’s rare that one lands in a place where I can photograph it. Last week, however, I got lucky and I was finally able to get some shots of one of these elusive butterflies.

Now that I have the images, I am faced with the difficult task of trying to identify the butterfly. There are a lot of brown butterflies with a numerous eye spots on the wings and to my untrained eyes, they all look pretty much the same. I think this one may be of the genus Lethe, but is it a Pearly Eye, an Appalachian Brown, an Eyed Brown, or something entirely different?

For now, I’ll fall back on an old habit and make up my own name for the butterfly and call it the Beautiful Woodland butterfly.

How do you decide which of your photos are your favorite ones? Do you rely on technical criteria, like sharpness, or do you rely more on the overall artistic impression? Do your memories of shooting an image factor into your calculations? Do WordPress statistics play any role in your thinking?

As I noted yesterday, my blog’s second anniversary, I am taking a brief pause from posting new photos to think about the blog and my photographic journey over the last two years. During this period, I though I would re-post some of my favorite postings. I am posting them in their entirety, because I think that my prose enhances the appeal of my blog (and I find that I enjoy the creative experience of expressing myself in my words as well as in my images).

I tend to photograph a lot of insects in the summer and birds in the winter, but some of my most memorable images come from my infrequent encounters with mammals, like this tender moment that I shared with a beaver family last summer that was visible one day during the daylight hours.

In response to my initial questions, I tend to give my greatest priority to the overall artistic impression and give little weight to WordPress statistics. Some of my best photos have relatively few views, while I have a few unexceptional images that have a lot of views.

Text of the original blog posting that first appeared on 18 July 2013:

Last Friday, after some violent thunderstorms, I visited my local marshland park, where the staff alerted me that three beavers were sleeping on a patch of dry land near their lodge, which apparently had flooded. The three North American Beavers (Castor canadensis) were all snuggled together and reminded me a little of puppies. I am working up some more images, but thought that I would give a sneak preview of coming attractions.

Do your review your photos rapidly before you choose the ones to post or do you carefully and systematically evaluate them and only then select the best ones?

I am often in a hurry.  Sometimes I will stop to work on a shot that I like before I have even reviewed the complete set of images. I generally  don’t work up postings in advance and I’ll write up the posting and push the “Publish” button with out realizing that I may have unmined gold waiting to be discovered.

Only later, when I go through the entire set of shots do I realize that I have a better shot than the one I posted and realize I should have at least posted both of them. If the differences are only minor, I won’t do an additional posting, but sometimes, like today, I feel compelled to post a second image.

As was the case in yesterday’s posting, this is a shot of what I think is an Eastern Carpenter Bee (Xylocopa virginica)—or possibly a bumblebee— on a Purple Coneflower (Echinacea purpurea). The angle and the lighting helped me capture a significant amount of the detail and texture of both the bee and the flower and the colors came through with a beautiful vibrancy. The bee was in an unusual position, which adds to the visual interest of the image.

This is one of my favorites of my recent images. You might think that this experience will teach me a lesson about the value of a full review before choosing images to process, but I suspect that this will happen again from time to time. I know my habits too well.

Yesterday was a beautiful, sunny day, but it was very breezy, which made it tough for me to get decent shots of bees in my neighbors’ garden. I am still going through my photos (and deleting a lot of them), but I was immediately drawn to this image of an Eastern Carpenter Bee (Xylocopa virginica) on a Purple Coneflower (Echinacea purpurea).

Although the dark background suggests the use of flash, I wasn’t using any flash and the shutter speed of 1/400 in the EXIF data is faster than the synch speed of my flash. I was trying to get as close to the bees as I could and the height of the coneflowers made it possible to get at eye level with the bee and get this head-on shot.

What adds drama to a photo? Sometimes it is the lighting of a scene or the positioning of a subject. These recent shots of Blue Dasher dragonflies (Pachydiplax longipennis) seem to have a bit more drama and are more “artsy” than many of my typical images.

Should I start wearing a beret now when I am shooting?

Two things really struck me when I first encountered this damselfly—its captivating blue eyes and its extraordinarily long abdomen.

Most damselfly fold in their wings when they are at rest, but damselflies of the Lestidae family keep them open and are commonly known as spreadwings. Only two members of this family are on the species list for my marshland park—the Swamp and the Slender Spreadwing—and this looks to me like might be a male Slender Spreadwing damselfly (Lestes rectangularis).

I would welcome a correction or confirmation of my identification, because I feel almost clueless when it comes to identifying damselflies.

Compared to the other dragonflies that I have photographed, the Eastern Amberwing (Perithemis tenera) is tiny, typically less than an inch in size (25mm), but it has such a distinctive look that it is easy to identify.

I was able to approach this dragonfly from the rear and from above as it was perched on some vegetation overhanging a muddy creek and I don’t think it sensed my presence, even though I was pretty close to it. .

It’s unusual for me to take a photograph of a dragonfly with my camera pointed upward, but this Bar-winged Skimmer (Libellula axilena) kept perching in the branches of a downed tree limb, enabling me to include a little patch of sky in some of the shots. This is a new species for me that was pointed out to me by fellow photographer Walter Sanford when we ran into each other at one of our favorite spots at our local marshland park. The second shot shows part of the wing pattern that is responsible for the common name of this species, “Bar-winged.”

It’s tough to photograph a dragonfly in flight, but when it chooses to hover, there is a slightly better chance of getting a shot. That was the case recently when I encountered this female Great Blue Skimmer dragonfly (Libellula vibrans) that was in the process of depositing her eggs in the water. As her mate circled overhead, the female dragonfly would hover over the water and then periodically dip the tip of her tail in the water before returning to the hovering position. I was able to get several images of the hovering dragonfly, but got only a single image of her depositing the eggs.

Looking at my recent postings, you might come to the conclusion that I neglect damselflies, the smaller, less colorful members of the Odonata family, in favor of dragonflies. Actually, I really like damselflies, but they are so small that it is difficult to see them most of the time and quite a challenge to get a clear shot of one.

As I was searching for dragonflies, I came upon this beautiful black and blue damselfly perched on a small branch near the edge of a muddy creek and was able to get an unobstructed shot. You might think that identification would be easy, but there is a whole group of damselflies, the bluets, whose members have various combinations of black and blue.

So far, I haven’t been able to identify this damselfly, but I find its combination of black and turquoise to be elegant and really attractive.

A few days after I stumbled upon a Common Sanddragon dragonfly, a new species for my favorite marshland park, I returned to the remote location with fellow photographer and local dragonfly expert Walter Sanford (who made the initial identification for me). Walter has a science background and his posting today of our encounter with the Sanddragons is full of fascinating scientific information as well as awesome photos of these beautiful little dragonflies. Be sure to check out his complete posting.

Common Sanddragon dragonflies (Progomphus obscurus) are anything but common.

Despite its name, this species is rare in Northern Virginia. Source Credit: Common Sanddragon, Dragonflies of Northern Virginia, by Kevin Munroe, Park Manager, Huntley Meadows Park.

Kevin goes on to cite Bull Run and Goose Creek, two streams where he has seen Common Sanddragons, and speculates they may be found at two other locations in Northern Virginia. Well, you can add a third location where sanddragons have been seen and it’s right in Kevin’s wheelhouse!

Mike Powell, a fellow amateur wildlife photographer and blogger, photographed a clubtail dragonfly at Huntley Meadows Park on 17 June 2014 that he was unable to identify. Mike’s description of the habitat where he saw the dragonfly piqued my curiosity, so I asked him to send me a photo of the unknown dragon. Turns out Mike discovered a Common Sanddragon —…

Female dragonflies are often less colorful and visible than their male counterparts, but are equally beautiful.

A week ago, I did a posting featuring the dark blue male Spangled Skimmer dragonfly (Libellula cyanea) and noted that the white stigma (markings) on the wings help in identifying this species. In today’s image, a female Spangled Skimmer appears to be a natural model as she smiles and poses for the camera

When you first catch sight of the fluttering flight of an Ebony Jewelwing damselfly (Calopteryx maculata) from a distance, it’s easy to think that it is a butterfly.

These damselflies are really weak fliers and they flutter slowly from one location to another nearby spot. Although they perch, they tend to do so on low vegetation and they don’t remain in one spot for very long, which makes it a challenge to get a decent photograph of one of them.

Their dark wings make them unusual and distinctive—all of the other damselflies that I have seen had clear wings—and help to set off the beautiful emerald color of their bodies.

According to bugguide.com, the Ebony Jewelwing’s scientific name Calopteryx maculata comes from the Greek “kalos” (beautiful) + “pteron” (wing or feather) and “macula” (a spot), a reference to the white spot near the tip of the female’s wing.

Last week I added the Common Sanddragon dragonfly (Progomphus obscurus) to the species list at Huntley Meadows Park, the marsh where I spend a lot of time walking and photographing. The park keeps a comprehensive list of species and it appears that this particular dragonfly had never before been observed and photographed within the park.

sand1_blog

 

I came across this dragonfly, which I recognized as some kind of clubtail, when I was hiking through a back area of the park. I was struck by the way the dragonfly was patrolling a small sandy stretch of a creek and kept returning to perches on that little beach. I took quite a few photos of the dragonfly, though I really wasn’t sure of its identity.

sand3_blog

The images would have remained unviewed on my computer for several days, but I mentioned my discovery to fellow blogger and photographer, Walter Sanford, who seemed to sense that I had captured something a bit out of the ordinary. He insisted that I send him a couple of images immediately, which I did. Walter tentatively identified the dragonfly as a Common Sanddragon and confirmed the identification with Kevin Munroe, who manages Huntley Meadows Park and is a dragonfly expert.

Kevin has a wonderful website, Dragonflies of Northern Virginia, that is full of fun and useful information about dragonflies in our area. In the section about Common Sanddragons, he notes, “Despite its name, this species is rare in Northern VA. In other parts of the country, where clean, sunny, shallow creeks with plenty of sandy/gravely banks are common, so too are Common Sanddragons. Our urban waterways are too influenced by stormwater, flowing fast and unchecked off impervious surfaces (roads, parking lots, roofs, etc.). This creates deeply incised, eroded banks and streambeds with excess silt, unstable flows.”

As a kind of experiment, I angled a couple of sticks in the sand to see if I could get one of them to perch on the stick. Although they kept returning primarily to the sand, a couple of times one perched on the stick and I got this shot.

sand2_blog

You may have noticed the raised tail in several of the shots. In other dragonflies, the “obelisk” position is a method of thermoregulation, but I am not sure if this is the case here—it might be related to efforts to attract a mate.

Buttonbushes are now blooming at my local marsh, attracting beautiful butterflies, including this Pipevine Swallowtail and this Great Spangled Fritillary.

I don’t know what it is about the Common Buttonbush (Cephalanthus occidentalis), but butterflies seem to find it irresistible. Several Pipevine Swallowtails (Battus philenor) flitted all around the bushes in frenetic motion, hardly every stopping to perch. The Great Spangled Fritillary (Speyeria cybele), however, seemed to take its time, lingering over each of the spiky spherical globes of the buttonbush.
