Persius Duskywing
Erynnis persius

Observation date: June 16, 2019
Submitted by: A_baldini
Specimen type: Photograph
Observation notes: Weather: Partly cloudy and 55-60 degrees. Notes: This species was less common than Pacuvius Duskywings at this semi-riparian area along the Well Gulch Trail. Based on what's visible on the dorsal side, I'm fairly confident this is a Persius Duskywing.
Status: Resident

Verified date: October 04, 2019
Coordinator notes: Not too many other species of Duskywing it could be.....persius can look like a small Rocky Mt. Duskywing but telemachus is an oak feeder and not found much north of Bear Ck. near Morrison in Jefferson County. Mike
