For the last several years fellow dragonfly enthusiast Walter Sanford and I have been trying to photograph a Tiger Spiketail dragonfly (Cordulegaster erronea), a relatively rare and elusive species. We have spotted multiple times, but had been unable to get any photos until this Thursday. Be sure to click through to the original posting to read Walter’s wonderful posting in its entirety. It provides the backstory to our encounter and some fascinating information about this species and some cool photos too.

A Tiger Spiketail dragonfly (Cordulegaster erronea) was captured along a small stream at an undisclosed location in Prince William County, Virginia USA. The specimen was photographed and released unharmed.

The first few images show Michael Powell, my good friend and photowalking buddy, holding the dragonfly while I shot some photographs.

I was really happy yesterday morning when I spotted a female Tiger Spiketail dragonfly (Cordulegaster erronea) while exploring a small stream in Prince William County, Virginia and absolutely thrilled when she started ovipositing, giving me a chance to capture these images. For several years I have been trying to photograph this elusive species. In the past I have gotten a glimpse of a Tiger Spiketail on several occasions, but never managed to get a shot of one.

Why have I had such problems? Kevin Munroe, who developed the wonderfully informative website Dragonflies of Northern Virginia, described the species in these words:

“This secretive and seldom seen forest dweller has an almost elven quality. It lives deep in mature woodlands and spends most of its life around tiny, almost invisible spring-fed seepage streams. When startled, it disappears into the leafy canopy, which is also where pairs fly to mate, often hidden for hours. Their larvae live in such small, food-scarce streams that they take several years to mature. Tigers live in smaller streams than any other Northern Virginia spiketail. Their numbers are relatively low, and it’s unusual to see more than one or two together. There’s a certain thrill to finding a Tiger Spiketail at its stream—you know you’ve stumbled upon a clean, quiet and special corner of whatever park you’re exploring.”

Tiger Spiketails fly patrols low above the water of these tiny forest streams. If you find the right kind of stream, you stand and wait, hoping that a Tiger Spiketail will fly by. If one appears, you might have a second or two to get off a shot of the flying dragonfly before it disappears from sight. You repeat the cycle and if all goes well, the dragonfly may come back again within fifteen to thirty minutes or you may never see it again.

I was really lucky yesterday. Earlier in the morning I had had several sightings of a Tiger Spiketail, but had gotten only a single very blurry shot. When a Tiger Spiketail flew into view, I immediately started tracking the dragonfly visually and I was shocked when she began to dip the tip of her abdomen in the water to deposit an egg, a process known as ovipositing. What this meant was that she would hang around in a spot for several seconds and then move upstream a bit and repeat the process.

Although I had the Tiger Spiketail in sight, getting a decent shot was a challenge. In addition to her lateral movements, she was also moving up and down as she deposited her eggs. Much of the stream was in the shade or the light was heavily filtered, so it was hard to get enough light to capture a moving subject. I managed to get a few reasonably sharp action shots of the Tiger Spiketail. If you double-click on the first image, you can actually see the dragonfly’s “spiketail” and other details including its beautiful markings and striking green eyes. The second shot gives you a better view of the environment in which I found this dragonfly, which is considered rare in the area in which I live.

Whenever I manage to capture of a new species, I am so excited that I do not worry much about the quality of the images. Before long, though, the excitement dies down and I will hit the trails again, determined and hopeful that I will be able to get some better shots. That crazy, quixotic vision is what drives most of us nature and wildlife photographers to go out repeatedly, always in search of the next best photo.
