Yesterday at Occoquan Regional Park I spotted this female Common Whitetail dragonfly (Plathemis lydia) as she was depositing eggs into the water. I managed to capture a short series of shots that help to illustrate what she was doing.

She would fly low over the water as in the first shot and then hover over what she determined was a good spot. When she was ready, she dipped the tip of her abdomen into the water, creating the circular ripples that you see in the second image. Immediately she returned to her starting position as the ripples began to spread. Sometimes she would repeat this sequence several times at the same spot, while other times she would move on to another spot.

What was the male doing at this time? A male Common Whitetail dragonfly, which I assume was the one with which she had just mated, patrolled a few feet directly over her as she was depositing the eggs. I am pretty sure that he was there to deter or fight off potential rivals that might try to interfere with the perpetuation of his genes.

Most of the dragonflies that I see at this time of the year—and there are a lot of them—are members of the skimmer family. This is the largest family of odonates (the insect order of dragonflies and damselflies) and includes the species most likely to be seen by a casual  dragonfly observer.

When I first started getting interested in dragonflies, I focused primarily on colors—there were blue dragonflies, white dragonflies, red dragonflies, and so on. Over time I began to notice more and more differences between somewhat similar species.

Today I decided to feature photos of two dragonflies that I spotted on Thursday at Jackson Miles Abbott Wetland Refuge. Both are male, both are blue, and both are perched in a similar position. The first one is a Spangled Skimmer (Libellula cyanea).  Even though it shares its blue coloration with several other species, the little white patches on the edge of the wings, known as “stigma,” are both distinctive and diagnostic. The second one is a Slaty Skimmer (Libellula incesta). It is probably the darkest colored dragonfly in our area in terms of both its body and its eyes, which sometimes appear to be almost black.

Do you see these two dragonfly species in your area? I encourage you to look closely at the ones that you happen to see and see if you can identify some of the differences. You may find yourself being drawn more deeply, as I have been, into the wonderful world of dragonflies.

As I was exploring Mason Neck West Park in nearby Lorton, Virginia last Saturday, fellow dragonfly enthusiast Walter Sanford pointed to a dragonfly perched at the top of a tree and said it would make a good “artsy” shot. He was right. Although some details are lost in the shadows, the simplified silhouetted view lets you focus on the essence of the dragonfly.

The patches on the inner wings indicate that it is one of the saddlebags dragonflies. I think it might be a Carolina Saddlebags (Tramea carolina), but there is also a chance that it could be a Black Saddlebags (Tramea lacerata).

I am not sure if Blue-fronted Dancer damselflies (Argia apicalis) are always happy, but the ones that I spotted yesterday at Jackson Miles Abbott Wetland Refuge seemed to be smiling at me.

The beautiful light blue color on their upper bodies and their striking blue eyes make Blue-fronted Dancers relatively easy to spot and to identify.

This past Saturday I was thrilled to spot this mating pair of Ebony Jewelwing damselflies (Calopteryx maculata). No, I am not a peeping Tom, but I do enjoy being able to see the male and female of a species together, so that I can compare their coloration and markings.

When it comes to damselflies, I just love the sidewards heart that their bodies create when they are in this mating position. I have been told that the process is somewhat brutal, but I like to think of it as romantic, two hearts joined as one.

I have always been fascinated by shadows and reflections, which often lend an additional element of interest to a more straightforward shot. When a recently emerged dragonfly, probably a Lancet Clubtail (Gomphus exilis), flew into a nearby tree, I was utterly mesmerized by the shadow that it cast onto the leaves of the tree. The shapes and patterns of the green leaves create an almost abstract backdrop for the scene that really drew me in.

Most of my images are detailed, realistic portraits of my wildlife subjects, but at certain moment I love to attempt to capture more “artsy” images like this one.

We are now in prime dragonfly season and many familiar species are reappearing, like this beautiful Needham’s Skimmer dragonfly (Libellula needhami) that I spotted on Wednesday at Occoquan Bay National Wildlife Refuge.

I love the beautiful orange-gold color on the leading edges of the wings of this species, a color that really sparkles in the sunlight. I was fortunate to capture this dragonfly in a way that blurred the background. Depth of field is always an issue in situations like this and you can probably see that the tips of the wings are not in sharp focus, but I am ok with that and think it helps draw the viewer’s eyes to the dragonfly’s main body and, in particular, to its wonderful eyes.

Earlier this week I did a posting that described the Eastern Amberwing dragonfly as “unmistakable.” When it comes to damselflies, that title almost certainly belongs to the very distinctive Ebony Jewelwing damselfly (Calopteryx maculata). There is no other damselfly in our area that has completely dark wings like the Ebony Jewelwing.

I spotted this handsome male Ebony Jewelwing on Monday at Occoquan Regional Park. How do I know it is a male? Well, the female has a conspicuous little white patch on her wings that is technically known as a “pseudostigma,” which this damselfly in lacking. Additionally, the little hoop-like appendage at the end of this damselfly indicates that it is a male.

These little damselflies like to spend a lot of time in the semi-darkness of shaded forest streams, like the location at which I photographed this Ebony Jewelwing.

Throughout the month of May I have struggled to identify the dragonflies and damselflies that I have photographed. So many of the species seem so similar that I have had to defer to experts for help. Over the years I have learned that the best way to get help on a Facebook forum is to misidentify a subject—some experts, who might not respond to a request for help, feel compelled to correct you and demonstrate their superior knowledge.

This past Friday at Jackson Miles Abbott Wetland Refuge, it was nice to spot a familiar dragonfly species that was immediately identifiable—there is simply no other dragonfly in our area the looks like an Eastern Amberwing (Perithemis tenera). Even the name is helpful in drawing attention to the key identification feature, the distinctive amber wings.

These dragonflies are among the smallest ones in our area, but they tend to perch on low vegetation overhanging the water (especially males like this one), so they are relatively easy to spot. Although they tend to be a little skittish, if you are patient and persistent you can snag some shots that show the beautiful details of the Eastern Amberwing dragonfly.

I was exploring a small creek in Prince William County, Virginia last week with fellow dragonfly enthusiast Walter Sanford when suddenly I spotted a dragonfly hanging almost vertically from a branch not far above the ground. It is always a good sign when a dragonfly is hanging vertically, because many of the uncommon species perch in this way. My initial thought was that it was a clubtail and I informed Walter, who was searching another part of the stream, that it had two yellow stripes on its thorax. He reminded me that most clubtails have two yellow stripes, but was interested enough to move closer to me.

Walter has a lot more experience with dragonflies than I do and he grew visibly excited when he looked at the dragonfly though his camera. It was not a clubtail at all, but a relatively uncommon Arrowhead Spiketail dragonfly (Cordulegaster obliqua). Not only was it an Arrowhead Spiketail, it was a female and females tend to be harder to find than males. As I got closer, I could see the “spike” protruding from the tip of the abdomen, which showed it was a female, and the telltale arrow shaped markings all the way down the abdomen. We believe that this was the first documented sighting of an Arrowhead Spiketail in Virginia this year.

The dragonfly was unusually cooperative and both Walter and I were able to take lots of shots without disturbing her. In fact, she was still on the same perch when we left, though she was absent when we returned an hour or so later.

In situations like this, Walter and I like to do companion blog postings independently. Our photography styles and personal backgrounds color the way in which we produce our blog postings and they help to give our readers different perspectives on the same subjects and situations.

I have provided an assortment of images that show the female Arrowhead Spiketail from different distances and angles. I decided to do them in a gallery style—if you want to see them in a larger format slide show, which I recommend doing, just click on any one of them and then click the arrows. You probably notice that some of the images are intended to help you to identify the dragonfly and others are more “artsy.”

Be sure to check out Walter’s companion posting. I will include a link to it after I have published this article and have a chance to check out Walter’s posting.

UPDATE: Walter’s posting is wonderful. In addition to some excellent photos of the dragonfly, Walter provides a lot of contextual information about the location at which we found it and additional information about the species. Click here to see his posting.

Survival in the wild is challenging even when you are able-bodied. The difficulties are multiplied when you have a major deformity, like this Gray Petaltail dragonfly (Tachopteryx thoreyi) that I spotted on Friday at Occoquan Regional Park.

I not sure what caused the sharp bend in the abdominal region of this dragonfly, but I observed that it was able to fly and to perch. Perhaps it is able to capture prey, but mating seems out of the question. I admire that the fact that it appears to be fighting for its survival.

For the sake of contrast, I am including a photo of another Gray Petaltail dragonfly that I observed the same day at the park.

I love to photograph dragonflies and damselflies when they are perched, but it is even more exciting to capture them in action. Now you may be wondering what kind of action I can possibly observe  and photograph. Dragonflies and damselflies seem to have two major biological imperatives—eating and mating. This posting focuses on the latter.

I was thrilled this week in Prince William County, Virginia to observe a new species of damselfly—the beautiful Aurora Damsel (Chromagrion conditum). Like many damselflies, the male Aurora Damsel has a black and blue coloration, but as an added bonus the male and female both have a bright yellow patch on the sides of their thoraxes (the “chest” area).

The first image shows the female, on the left, and the male in what is known as the “tandem” position. If you look carefully, you can see the yellow patched on both of their bodies. Often this position is a prelude to mating, and that certainly was the case in this situation. The second image shows the couple in the mating position known as the “wheel,” which often resembles a sideward-facing heart.

When mating is completed, the couple remains attached and they fly together to the water in order for the female to deposit her eggs in a process known as “ovipositing.” In the final image, you see the female ovipositing in some vegetation floating on the surface of the water. You don’t see it here, but sometimes the male will push down so hard that the female ends up partially submerged in the water.

This time of the year is always exciting for me as my favorite dragonfly species begin to emerge—it is like renewing a relationship with old friends after an extended absence. On Monday at Occoquan Bay National Wildlife Refuge I was thrilled to spot my first Calico Pennant (Celithemis elisa) dragonflies of the season.

As dragonflies go, Calico Pennants are small, a little over an inch (25 mm) in length and very colorful. In addition to their bright red (male) and yellow (female) bodies, they have beautifully patterned wings. Like other pennant dragonflies, Calico Pennants like to perch at the very tip of flimsy grasses and other vegetation. That makes them fairly easy to spot, but tough to photograph as they flap in the slightest breeze like a pennant.

I spotted a number of male Calico Pennants during my visit, but only a single female, the one that is mating with a male in the final photo. For those of you with curiosity or prurient interest, the couple are hooked up in what is often referred to as the “wheel position.” Anatomically speaking, it is a bit confusing, but you have to admire the couple’s acrobatic flexibility. The first two photos show perched males, with the initial photo a back-lit image that shows wing details and the second one a more traditional pose that highlights the body coloration.

Do you like to hang out in the swamp? Swamps may not be the most hospitable place for humans, but they provide a wonderful environment for all kinds of photogenic creatures. For example, the bright yellow Prothontary Warbler that I featured yesterday likes to hang out in a wooded swamp, unlike most warblers that prefer trees in a drier environment.

As I was photographing that bird two weeks ago at Occoquan Bay National Wildlife Refuge, I noticed some very large dragonflies flying around in the same area.  I recognized them as Swamp Darner dragonflies (Epiaeschna heros) and I was thrilled when one of the females decided to deposit some eggs in a fallen log not far from where I was standing observing the warbler. I had to bend down a bit, but essentially my feet stayed in the same spot.

It is definitely cool to be able to photograph two such colorful species from the same spot. The experience is a good reminder not to get so focused on your primary subject that you lose sight of what is happening around you. You never know when an equally good or even better subject may be at your feet, above your head, or to your right or left.

It’s always wonderful to see large colorful butterflies, like this Red-spotted Purple butterfly (Limenitis arthemis astyanax) that I spotted last week at Jackson Miles Abbott Wetland Refuge. I don’t know about you, but I find the spots to be a bit more orange than red and the body looks more grayish-blue than purple. Maybe the people responsible for naming the species say it in a different light. 🙂

Yesterday I was thrilled to get a shot of this pretty Red-banded Hairstreak butterfly (Calycopis cecrops) at Occoquan Regional Park. These tiny butterflies are only about an inch (25mm) in length, so you really need a macro lens to get a close-enough shot that reveals all of the butterfly’s wonderful colors and patterns. It is also nice to be able to see the little “tails” protruding from the hind wings that I believe are responsible for the name “hairstreak.”

Do you remember the first blog post that you ever wrote? In my first blog posting on July 7, 2012, I featured a photo of a Blue Dasher dragonfly (Pachydiplax longipennis). Every year since then whenever I see my first Blue Dashers of the season, I recall my excitement I experienced in being able to photograph that first dragonfly. I did not realize at that time how “addicted” I would get to photographing these beautiful little creatures.

I spotted this handsome male Blue Dasher this past Tuesday at the edge of a small pond at Jackson Miles Abbott Wetland Refuge.

Earlier this week I spotted this male Zabulon Skipper butterfly (Poanes zabulon) while I was exploring Occoquan Regional Park. I am not one hundred percent sure of my identification, given that there are hundreds of different species of skipper butterflies, but I am hoping that I am correct for the simple reason that I find the name “Zabulon” to be exceptionally cool. As some of you may know from the URL for my site, my middle initial is Q, which stands for Quentin, and I am irresistibly drawn to names that begin with infrequently used letters like Q, X, and Z.

In terms of the image itself, I really like the way that the warm orange tones of the butterfly stand out amidst the cooler shades of green in the foreground and in the background.

Are you so used to the common beauty that surrounds you every day that you no longer see it? What does it take for you to stop and take notice and maybe even pull out a camera to photograph a subject?

Almost six years ago I read a blog posting by fellow photographer Lyle Krahn that talked of a concept called “stopping power” and that posting has stuck with me to this day. Here’s a portion of that posting that describes the concept, “I think every beautiful scene has stopping power. That’s my term for the ability of a scene to make a person stop hiking or driving in order to pull out a camera and make images. Did you ever wonder what makes you stop? Do you ever hear the music?”

I try to pay attention to even the most common subjects and when it comes to dragonflies, that means the aptly named Common Whitetail (Plathemis lydia). Common Whitetails are among the first dragonflies to appear in the spring and among the last to disappear in the autumn. You can find lots of Common Whitetails almost everywhere it seems.

On Tuesday at Occoquan Bay Regional Park I stopped and photographed some Common Whitetail dragonflies as I was searching for some more exotic dragonfly species. This early in the season the Common Whitetails seem to be hanging out at a distance from the water—later in the summer I tend to find them buzzing around ponds and swamps.

The first two shots below are of male Common Whitetails. Although mature males are white, when they are young they have brown bodies similar to those of females. However, males have different patterns on their wings and the second and third images show those differences and may help you to distinguish immature males from females.

So, what has “stopping power” for you? I encourage you to think about that question, to make an effort to lower your threshold, and to look for the uncommon beauty in common subjects.

Yesterday I spotted this male Lancet Clubtail dragonfly (Gomphus exilis) while exploring Jackson Miles Abbott Wetland Refuge, a relatively small park not far from where I live. The dragonfly was perched on some leafy vegetation overhanging the water and I almost fell into the pond while trying to frame the shot. Fortunately I achieved my desired result by hanging over the edge of the steep bank.

If you look at the end of the “tail,” which technically is called the “abdomen,” you can see the enlarged section that gives rise to the term “clubtail.” Compared to the family of skimmers, which include most of the dragonflies that you probably see, like Blue Dashers and Common Whitetails, clubtails are relatively uncommon and it is always exciting for me to spot one.

I was particularly struck by this dragonfly’s brilliant blue eyes. For some reason I find blue eyes to be especially beautiful, irrespective of the species.

During my church retreat in Orkney Springs, Virginia this past weekend, I played hide-and-seek with a Common Green Darner dragonfly (Anax junius). It repeatedly flew teasingly close to me, trying to entice me to chase it.  I took the bait and pursued the big dragonfly for quite some time as it flew in and out of the reeds.

It tried to hide by hanging from some vegetation by the tips of its tiny toes—the second photo shows my initial view of the hidden dragonfly. By moving to the side and crouching low, I was able to peer through the vegetation and eventually spot the dragonfly. Realizing that it was found, the dragonfly tilted its head toward me and smiled, as you can see in the first image shown below.

Natural camouflage in the coloration of birds and insects enhances their survivability, but it really makes them hard to find and photograph. Last week I made trips on two consecutive days to Patuxent Research Refuge in Laurel, Maryland to search for dragonflies. I have already posted photos of a Common Green Darner and a Swamp Darner that I saw during those trips—both of those dragonflies are large and colorful and relatively easy to spot.

One of the main purposes of the trip, though, was to look for a Harlequin Darner (Gomphaeschna furcillata), a species that is rare in our area and hard to spot in the field. Why? The Harlequin Darner is small for a darner, about 2.2 inches (56 mm) in length, and is in a sub-group know as pygmy darners. Its subdued coloration of gray and brown provide excellent camouflage, particularly because it often perches on tree trunks. The Harlequin Darner requires a specific type of habitat and has a flight season of only a few weeks in early spring.

On my first trip, I traveled with fellow dragonfly enthusiast and blogger Walter Sanford. We searched in vain for several hours, sometimes side-by-side and sometimes separated. As luck would have it, Walter located a Harlequin Darner at a moment when I was pretty far away. Alas, the dragonfly flew away shortly after I arrived at his location. Fortunately, Walter captured some excellent shots which you can see (along with some additional information) on his blog posting from last week. As it turned out, that was the only Harlequin Darner that either of us saw all day.

The following day I decided to return alone, hoping that I too might spot a Harlequin Darner. I saw a good number of dragonflies, including the Common Baskettail that I captured in flight, but as the day progressed, I began to wonder if I would ever find a Harlequin Darner. I kept searching and finally I saw a dragonfly perch vertically on the trunk of a tree. The lighting was harsh and the shadows distorted the proportions of the dragonfly, so I wasn’t sure what kind it was. At this point, though, I was focused on getting a shot and would worry later about identifying the dragonfly. The dragonfly remained in place for about 30 seconds and then flew away.

Well, it turns out this is a female Harlequin Darner. Every time that I see a new species for the first time, I am thrilled to get any kind of recognizable images. In the future I will try to get better shots, but for now I am content that once again my persistence paid off.

It’s great to celebrate small victories.

It is a little unusual for me to post photos of the same species twice within a few days, but I could not help myself when I captured this image of a female Swamp Darner (Epiaeschna heros) that provides such a wonderful view of her remarkable eyes.

Dragonfly eyes are always amazing, with their multiple lens that give the dragonfly almost 360 degree vision and the ability to see parts of the color spectrum that are invisible to the human eye. What is particularly striking about this Swamp Darner’s eyes are its varied colors and patterns. Wow!

The second image shows the same female Swamp Darner as she rested in a tree prior to beginning the task of depositing her eggs, which is what you see her doing in the first shot. I captured these images this past Tuesday during a visit to Patuxent Research Refuge in Laurel, Maryland.

Do you like a fun photo challenge? Try taking a photo of a dragonfly as it zooms on by you.

Here’s an image I captured on Tuesday of a Common Baskettail dragonfly (Epitheca cynosura) in flight at Patuxent Research Refuge in Laurel, Maryland. In case you are curious, Common Baskettails are about 1.6 inches in length (41 mm).

So how would you go about getting a shot like this? I would say that the key requirements are patience and persistence. The first thing that I usually do is observe the dragonfly’s flight path and try to determine if there are particular places where it tends to hover or turn around. This particular dragonfly was flying low and not too far from the shore of a small pond.

Focusing is the biggest problem. Some photographers like to pre-focus on an area and wait for the dragonfly to fly into that area. Others will rely on the auto-focus capabilities of their cameras. I have had almost no success with those techniques. What I usually do is put my camera’s focus into manual mode and literally change focus on the fly as I attempt to track the dragonfly in the air.

I like to use my Tamron 180 mm macro lens, because it gives me a decent amount of reach and frees me from worrying about zooming in and out. I have found that simultaneously zooming and focusing manually while tracking the dragonfly is like patting your head and rubbing your stomach at the same time—it is theoretically possible but tough to accomplish in real life.

If you click on the image and view it in a larger size, you will see that I was fortunate to get my focus just about right for the middle of the dragonfly’s body. The shutter speed of 1/1000 of a second was fast enough to freeze most of the movement of the wings.

Needless to say, I took a lot of shots and my success rate was very low. Perhaps this is not your idea of a “fun” challenge. In that case, I would encourage you to find some area of your life and challenge yourself to do something that is difficult. Even if you are not successful, I think even the effort will help you to grow, especially in self-knowledge and self-awareness.

Odonata is an order of insects that includes dragonflies and damselflies. In general, dragonflies tend to be larger and perch with their wings held out to the sides, while damselflies are smaller, have more slender bodies, and most  hold their wings over the body at rest. I try to pay attention to members of both damselflies and dragonflies, but often spend more time with the latter group, because they are easier to find and photograph.

In the interest of equality, I decided to devote today’s post to some of the female Fragile Forktail damselflies (Ischnura posita) that I have observed this past week. The three images show female Fragile Forktails in three of their main activities—perching, eating, and ovipositing (laying eggs). I have no recent shots of the mating that precedes the ovipositing, so I will leave that to your imagination for now.

As you probably noted, the coloration of these lady damselflies varies. The damselfly in the first image with the distinctive markings is an immature female. As the females age, they acquire a bluish coating that is sometimes referred to as pruinescence, which you can especially see in the second image. The third image shows a damselfly arching her long abdomen as she deposits eggs in the debris floating on the surface of a small pond.

On Monday I traveled to Patuxent Research Refuge in Laurel, Maryland with fellow dragonfly enthusiast and blogger Walter Sanford to search for dragonflies. One of the highlights of the visit for me was spotting this female Swamp Darner dragonfly (Epiaeschna heros) as she was laying her eggs. As you can see from these two photos Swamp Darners lay their eggs directly into wet wood with their blade-like ovipositor, unlike many other dragonflies that lay their eggs onto the water.

Swamp Darners are among the largest dragonflies in our area, about 3.4 inches in length (86 mm) and it was impressive to watch this one flying about over a swampy area of the refuge.

Yesterday was a wonderful day for searching for dragonflies at Occoquan Regional Park and among my finds was this beautiful female Painted Skimmer (Libellula semifasciata). This is the first one of the season for this species, which is relatively common compared to most of the early spring species. The patterns on the wing make this species stand out and definitely help in identifying.

I love the way that the different colors on this dragonfly work so well together and give this dragonfly a refined and rather sophisticated look. It is an additional bonus that those colors are mirrored by the background colors in this image.

When presented with a downward-facing flower, this Eastern Tiger Swallowtail butterfly (Papilio glaucus) was forced to choose an unusual angle of attack. Seeming defying gravity, this acrobatic butterfly hung upside down as it probed upwards earlier this week at Prince William Forest Park in Triangle, Virginia.

If this were an Olympic competition, I would give him a 10 for both his technical skills and overall artistic impression.

I sometimes complain about the names given to species and how little they correspond to what I actually see in the field. That certainly was not the case yesterday when I spotted a Twin-spotted Spiketail dragonfly (Cordulegaster maculata) along a creek in Northern Virginia. If you look closely at the image, ideally by double-clicking it, you will see the double row of spots on the dragonfly’s abdomen (the “tail”) and the long pointed ovipositor extending well beyond the end of the abdomen, the “spiketail.”

As I post photos of dragonflies, I realize that it is hard for readers to get a feel of the relative size of these beautiful creatures. The Uhler’s Sundragons that I have featured recently are about 1.7 inches in length (44 mm). A Twin-spotted Spiketail, by contrast, is much larger, about 2.8 inches in length (69 mm).

Both of these species are uncommon to rare in our area, primarily because of their specific habitat requirements—they require clean forest streams, which are not common in the Washington D.C. metropolitan area and they have an early and short flight season of only a few weeks.

You know you are pretty close to a dragonfly when you can see individual grains of pollen on its head and body. I photographed this Uhler’s Sundragon dragonfly (Helocordulia uhleri) on 12 April alongside a creek in Northern Virginia. Ideally it would be best to stabilize macro shots taken at this close a range by placing the camera on a tripod, but in a field situation with a live subject, that is rarely possible.

If you click on the individual images, you will see some wonderful details, like the ommatidia, the individual optical units that make up the amazing compound eyes of these dragonflies.

As we move deeper into spring, more and more butterflies are starting to appear, like this beautiful Zebra Swallowtail (Protographium marcellus) that I spotted yesterday at Accotink Bay Wildlife Refuge. Zebra Swallowtails are most often associated with pawpaw trees, which is helpful to know, though I must confess I don’t know how to identify a pawpaw tree. What I do know is that these butterflies are constantly on the move and fly in such an erratic way that I have trouble getting a decent photograph of one.

Yesterday I managed to get a shot of a Zebra Swallowtail when it paused momentarily at a small tree, perhaps a possible pawpaw. What I like about the shot is that it shows well the colors of the butterfly as well as its long “tails.” I could not decide how much to crop the image, which was taken from a pretty good distance away, so I am including tow versions of the image. Personally I am drawn most to the second one, but recognize that many folks may prefer the first versions, which draws you more quickly to the butterfly’s beautiful details.
