Flight season: early June to late August.
Population: uncommon, probably because it is seldom encountered.
This damselfly is crepuscular, becoming active very late in the afternoon and flying well into the evening.
Local sightings to date are from the marshy north shore of Stoco Lake.
Length: about 35 mm, thin and attenuated.
Mature adults are unlikely to be confused with other species.
