For the last few weeks I have been diligently searching for Fine-lined Emerald dragonflies (Somatochlora filosa), a relatively uncommon dragonfly species both nationally and locally. They seem to prefer a coastal plain and are active for only about a month, generally the month of September. Over the past five years I have photographed them at Occoquan Bay National Wildlife Refuge, though usually I only have a few sightings each year.
What makes this dragonfly so special? In his excellent website Dragonflies of Northern Virginia, Kevin Munroe described some of the allure of this particular species— “One of Northern Virginia’s most rare dragonflies, possibly our rarest, this species is seldom seen and little known throughout its range, from New Jersey to Florida, and west to Kentucky and Texas. Most field guides describe its breeding habitat as ‘unknown’.”
On the 9th of September, a fellow dragonfly enthusiast photographed a Fine-lined Emerald at the wildlife refuge, the first known sighting of the year. I encountered him that same day after his sighting and, encouraged by his success, I redoubled my efforts, but came up empty-handed for this species. On the 13th of September, I was equally unsuccessful.
Finally on the 14th of September, I spotted a Fine-lined Emerald in flight. Quite often Fine-lined Emerald dragonflies patrol at knee to chest height along the roads that run parallel to the shoreline. I was able to track the dragonfly as he flew back and forth along the road and was excited when I saw him perch. Usually dragonflies of this species perch at an angle or hang vertically from bare stalks of vegetation. The first photo below is not a very good photo, but it is good enough to document my first Fine-lined Emerald dragonfly of the season.
An hour or so later, I spotted another Fine-lined Emerald in the same general area. It might have been the same individual, but it is hard to know for sure. This time the lighting was better and the dragonfly chose a more photogenic perch. In the final two photos, you get a look at the dragonfly’s striking emerald eyes and beautiful markings. I initially thought the red, flowering stalk was Eastern Gamagrass, but now I am not sure. In any case, the red of the vegetation provides a nice contrast with the dominant greens in the rest of the last two images.
Once again, my persistence paid off. I will almost certainly be returning to this location with hopes of getting some additional shots of the Fine-lined Emeralds and getting my first shots of the year of Autumn and Blue-faced Meadowhawks, two species of little red dragonflies that appear during the late summer and early fall.
