Persius Duskywing
Erynnis persius

Observation date: June 21, 2024
Submitted by: Cascade Colors
Specimen type: Photograph
Observation notes: I really don't know; this individual seems pretty worn, too. But Persius information indicates it has the fewest/most indistinct spots, which is why I suggested this species.
Status: Resident
Verified by: mikefisher
Verified date: July 22, 2024
Coordinator notes: Looks like a male Persius except the spots on the hindwings which could be aberrant? This species most fits the location...the Rocky Mountains Duskywing has more gray on the ufw but not spots on the uhw as the one in your photo. I should place to "Cannot Identify" but it makes little difference...neither species represents any new record or range extension...both are recorded from Grand County. Mike
