Persius Duskywing
Erynnis persius

Observation date: June 28, 2019
Submitted by: HansPG
Specimen type: Photograph
Observation notes: Pleasant mostly-sunny midday in Yellowstone National Park near the Calcite Springs Overlook. The butterfly was seen not-long dead (the abdomen is clearly damaged) on the edge of the road with its underside up while watching a cinnamon bear cub a short distance off the road and down the hill (which some idiot then decided to go visit, distracting everyone from anything else).

Coordinator notes: Would need to see upper side of wings to be 100% sure, but pretty sure it's E. persius.
