Coordinator notes: This is actually a Hoary Elfin, Callophrys polios. The Brown Elfin has a noticeable reddish tinge to its underside, and it lacks the frosting which is clearly evident on the Hoary Elfin. Both use the same host plant, however (bearberry). This one was probably “smelling” the scat to see if it wanted to take in nutrients from it. Anyway, thanks for submitting your sighting!
