Callophrys spinetorum
This light brown butterfly rested on yarrow (Achillea sp.) for a few seconds. It fed on the flower's nectar and was covered in yellow pollen. The dorsal forewings are marked with a white line, while ventral wings are wavy-lined and black-spotted. Antennae and legs are patterned an alternating black and white.
Seen at the Ross Dam trailhead in North Cascades National Park.

Thank you, Neil!
Beautiful spotting, Mauna.
Updated the ID. Thanks, Brian.
I didn’t know what plant the elfin was feeding on. There was a beetle on it too but I couldn’t get a picture before it flew away. I’ll look at C. spinetorum and compare it to the other similar species I’ve seen on Bugguide. Thanks, Brian!
Awesome spotting Mauna! Yarrow is a great wildflower to watch for a variety of insects that feed on it. I agree with Callophrys sp. Also take a look at Callophrys spinetorum (thicket hairstreak).
Hi Robert! I agree. Thanks so much for the suggestion.
Mauna it looks to be in the genus Callophrys (Elfins)
