Posts Tagged ‘Stream Cruiser dragonfly’

Can a dragonfly smile? I seemed to detect a cocky little smile when I moved in close for this shot of a handsome male Stream Cruiser (Didymops transversa) last Thursday in Prince William County. The macro view also allowed me to appreciate the beauty of his two-toned eyes and to note the curious-looking “chin strap.”

The second shot shows the entire body of the Stream Cruiser, a medium-sized dragonfly that is about 2.2 inches (56 mm) in length. The image also gives you a sense of the environment in which I spotted him—a large expanse of interrupted ferns adjacent to a stream.

Last week I was delighted to spot several more Stream Cruiser dragonflies (Didymops transversa) while wandering about in Prince William County. This handsome male Stream Cruiser  looked like he could have starred in the well-known “got milk?” publicity campaign in the United States that featured photos of celebrities with milk mustaches and was designed to make milk more interesting and to emphasize its wholesomeness.

The print campaign with the the milk mustaches was started by the Milk Processor Education Program (MilkPEP) as a follow-on to a very popular series of television commercials in which people went to extraordinary lengths to make sure they did not run out of milk, according to this Fast Company article about the history of the Got milk? campaign.

Celebrities almost literally lined up to participate in this campaign and famous photographer Annie Leibovitz photographed more than 180 of the advertisements, according to the aforementioned article. One of the few requirements for participation in the campaign was that the celebrities had be milk-drinkers—I think they might have waived that requirement for Kermit the Frog—which was a problem for Whoopi Goldberg, who is lactose-intolerant. However, she was featured when the campaign ran an advertisement for lactose-free milk.

I don’t drink very much milk these days, but have fond memories of growing up with milk in my cereal bowl each morning. Got milk?

I have been having a really successful spring season in photographing dragonflies. Shaking off some of the winter doldrums, I have spent endless hours this month tramping about in a variety of habitats searching for these magical little creatures. I feel like I am now sprinting to the finish of a marathon on this final day of April

I was amazed to spot Stream Cruisers (Didymops transversa) on Monday at Occoquan Regional Park. I have seen Stream Cruiser dragonflies before, but never at this location. I was able to get shots of both a male (in the first photo) and a female (in the second photo). You can easily see the difference, I think, between the two genders, especially at the ends of their abdomens (the “tail”). Both of them, though, have the same long legs that always make their perching positions seem. a little awkward.

Earlier this spring, I spotted a large exuvia, the discarded exoskeleton of a dragonfly that has emerged, that my friend and fellow dragonfly enthusiast Walter Sanford was able to identify as being from a Stream Cruiser. I have included a photo of that exuvia as a final photo to give you a sense of the shape of the final stage of the water-dwelling nymph before it crawled onto dry land and began its metamorphosis to a new and exciting stage of its life as a dragonfly.

On Thursday I was excited to spot these two Stream Cruiser dragonflies (Didymops transversa), one female and one male, in a sunny area adjacent to a creek that I was exploring in Prince William County, Virginia. Authorities have closed the park that I was visiting to vehicular traffic, so I had to hike in to reach my target area, which took over an hour and a half each way.

It was the end of a long and tiring day and I had already begun the trek back to my car. By 4:00 in the afternoon, much of the trail along the creek was in the shade. Periodically, though, I would pass patches of sunlit vegetation and I stopped to explore them, knowing that many dragonflies like to bask in the sunlight. I was searching one such spot when my eyes detected a dragonfly in flight. I was able to track the dragonfly in the air and to see it land. The male Stream Cruiser (shown in the second photo below) perched at an odd angle on some low-hanging vegetation, but I managed to get a shot of it before it took off again.

I decided to stay in that spot and wait and after a while another dragonfly flew by, landing this time much higher in the vegetation. Initially I thought that it might be the same dragonfly that I had already photographed, but when I got closer, I could see that the second one (shown in the first photo below) was a female. The female Stream Cruiser chose to perch about chest-high, so I was able to get a much better angle for this shot than for the first one and compose the image more carefully.

This experience is a good reminder for me to stay alert at all times when I have my camera in my hands until I am actually back to my car. I had not even been thinking of Stream Cruisers, a species that I have seen only a couple of times previously, when I decided to make this trip. However, I was ready when this opportunity unexpectedly presented itself to me.

I cringe a little sometimes when well-meaning folks see my photos and say, “You are so lucky.” Yes, I have more than my share of good fortune, but it often takes hours and hours of effort for a decisive moment to arrive and even then I have to be quick enough and skillful enough to get a shot. Rather than going to the trouble to explain all of that, though, I will usually nod my head and agree that I was lucky to get my shots.

On the same day that I saw the Common Whitetail dragonfly that I featured yesterday in my blog posting, I was thrilled to have the chance to photograph an uncommon dragonfly, a male Stream Cruiser (Didymops transversa). I had never before seen a Stream Cruiser, but local dragonfly expert and fellow photographer Walter Sanford had observed them in the past at Accotink Bay Wildlife Refuge and offered to guide me.

It’s somewhat of an understatement to say that Stream Cruisers are hard to spot. The are not very big (about 2.2 inches (56-60mm) in length), they are skittish, and they often perch on the stems of low vegetation. During the hours that we searched for them, I observed a couple of probable Stream Cruisers in the air, but lost them in the blur of the vegetation and never saw a single one land. Walter saw the first one of the day, a female, and posted an awesome photograph of the beautiful dragonfly in a blog posting yesterday. Unfortunately for me, I was unable to make it to the dragonfly’s location before she flew away. Walter spotted a few more Stream Cruisers during the day, but each time I couldn’t get there quickly enough to see one.

I was beginning to think that I was going to end up empty-handed for the day when Walter called out that he had spotted a male perched in the underbrush. This Stream Cruiser was cooperative enough to stay perched as I rushed to try to get a shot. I had my Tamron 180mm macro lens on my camera at that moment. The dragonfly and the stem on which it was perched were so small in the viewfinder that my camera’s autofocus would not lock on my subject, so I had to resort to focusing manually. Dragonflies have so many fine details that it is really hard to tell when they are in focus. This image was the best I could get after cropping the initial shot quite a bit.

I decided to push my luck and see if I could get a better shot with my Tamron 150-600mm lens that I use primarily to photograph birds. Amazingly the dragonfly stayed put while I changed lenses. Once again I had to focus manually, which is an even bigger problem with this lens, because the focus ring is located really close to the lens mount. It’s hard to hold the camera steady and focus manually at the same time.

Here’s an image that I shot at 600mm. I managed to get the eye pretty sharp and to capture some of the details of the dragonfly’s incredibly long legs, but the depth of field was so shallow that the abdomen is out of focus. Normally I will try to move around the subject to be as parallel as I can be, but in this case I stayed fixed at one spot and remained as immobile as I could.

It is really nice to start off this dragonfly season with a new species. If you want to learn more about the Stream Cruiser dragonfly, check out this page from the Dragonflies of Northern Virginia website (and stay tuned for Walter’s shots of this dragonfly that should appear tomorrow morning in his blog).
