Unicorn Clubtail dragonflies (Arigomphus villosipes) were spotted at several locations along the shoreline of Painted Turtle Pond, Occoquan Bay National Wildlife Refuge, Prince William County, Virginia USA.

All of these individuals are males, as indicated by their terminal appendages.

The title of the preceding photograph is “The Miracle Shot,” so named because I was able to take one and only one photo of this male before he flew away and the subject is actually in focus!

The last photo shows an especially clear view of the male’s terminal appendages. Zoom-in on the photo and you should notice that the epiproct (“inferior appendage”) for Cobra Clubtail is essentially a wide plate with two prongs.
