Rocky Mountain Duskywing
Erynnis telemachus

Observation date: April 25, 2024
Submitted by: DeepSkyKelly
Specimen type: Photograph
Observation notes: I'm still never certain with duskywings. I'm leaning toward Rocky-Mountain because the season is right, the habitat is right, the wing patterns are reasonably close, and (as Glassberg mentions) it looks like there are a few spiky gray hairs on the back of its white thorax.
Status: Resident

Verified date: May 01, 2024
Coordinator notes: I agree. the most likely alternative (afranius) is smaller and has few white spots on the FW.
