Submitted by: blgreco
Specimen type: Photograph
Observation notes: None.
Status: Resident
Verified by: mikefisher
Verified date: May 17, 2026
Coordinator notes: I agree with your ID...looks like a newly emerged male. At lower altitude with the early date it would probably be Erynnis afranius. The two are rarely found together and afranius has two broods over the season. Mike
