Blue-ringed Dancer damselfly (female)

Identification of tan damselflies, such as the one shown below, can be a source of great frustration. Many species of tan damselflies look virtually identical: sometimes they are immature females and males; sometimes they are adult females. Very confusing!

29 AUG 2019 | HORP | Blue-ringed Dancer (female)

This individual is a female Blue-ringed Dancer damselfly (Argia sedula), spotted during a photowalk with Michael Powell along Popes Head Creek at Hemlock Overlook Regional Park (HORP), Fairfax County, Virginia USA.

The Backstory

Mike Powell and I explored a segment of Popes Head Creek near the confluence with Bull Run. We saw only three types of damselflies along the rocky stream: Blue-fronted Dancer (Argia apicalis), Blue-ringed Dancer (Argia sedula); and Powdered Dancer (Argia moesta). This individual doesn’t look like either a female or male for any of those species. Stumped, I was. So I consulted Dr. Michael Moore for help in identifying this specimen.

This is a female Blue-ringed Dancer. They are quite variable, but usually have the last three abdominal segments pale like this [one]. Also, I think there is a very slight amber tint to the wings which is typical of female Blue-rings.

Dr. Moore’s new Web site is a treasure trove of helpful resources.

Sincere thanks, Dr. Moore!
