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).

Mauna it looks to be in the genus Callophrys (Elfins)
