Sometimes I can get an indication of the species of a dragonfly by the way that it perches. Most skimmer dragonflies, the family of dragonflies that you are most likely to see, perch horizontally, sometimes on the ground or on vegetation. Other species perch vertically, hanging from vegetation. Finally, there are some dragonflies that never seem to perch and spend most of their time patrolling in the air—when they do take a break from flying, they often perch high in the tree canopy, where they are extremely hard to spot.
Stylurus is a genus of dragonflies whose members are commonly known as “Hanging Clubtails,” because of their habit of hanging nearly vertically when they perch. This past Tuesday I was thrilled to spot a male Russet-tipped Clubtail dragonfly (Stylurus plagiatus), one of the “Hanging Clubtails,” during a visit to Occoquan National Wildlife Refuge with fellow dragonfly enthusiast Walter Sanford.
During this summer I have been blessed to spot Russet-tipped Clubtails several times at two separate wildlife refuges. As the dragonfly season starts to draw down, it is special to find some of my favorites again, never knowing if it will be the final sighting of that species for the year.
The image below was my second sighting of a Russet-tipped Clubtail in the same general area. A short time earlier I had spotted another male Russet-tipped Clubtail in the trees, but it flew away before I could get any good shots of it. This may well be the same dragonfly, albeit in a different perch.
If you look closely at the image below you can see how the dragonfly is clinging to the leaf and hanging almost vertically. You can also note the prominent “club” that makes it easy to identify as a clubtail dragonfly and the terminal appendages (the shape at the end of the abdomen) show that this is a male. As you can imagine, dragonflies that perch this way are hard to spot—if they don’t move, it is easy to miss them.
Our weather has turned cooler now as we move deeper into autumn (or will begin it soon, depending on which calendar you use for the seasons). It is premature to start a countdown for the dragonfly season, but already I am noting diminishing numbers of certain species. Will I see another Russet-tipped Clubtail this season? If I am lucky, perhaps there will be another. For now I will simply say au revoir—one of the French ways of saying good-bye , with a literal meaning of “until we meet again.”
