Specimen type: Photograph
Observation notes: None.
Status: Resident
Verified by: mikefisher
Verified date: September 18, 2015
Coordinator notes: Looks like this is the Persius Duskywing. The Rocky Mountain (E. telemachus) is more gray on the forewings. The locality area is doubtful for telemachus which feeds on oak. Persius uses pea-family plants for hosts. Mike
