Persius Duskywing
Erynnis persius

Observation date: July 16, 2023
Submitted by: ezeemonee
Specimen type: Photograph
Observation notes: Near St Peter’s Dome Trail. Sunny day in the 70’s F between 9K-10K elevation.
Status: Resident
Verified by: mikefisher
Verified date: September 20, 2023
Coordinator notes: Pretty worn for identification...I can see hyaline spots on the right wing (toward the wingtip) and the hindwing spot pattern is clearly most like persius and not that of Erynnis horatius (an oak feeding species) and would be less likely to be found in the altitude range you indicate.
