Coordinator notes: Your ID is correct...a newly emerged male. By the way Byron...I am going to sit on your submission of the Northern Cloudy wing from July, 2016...its a tough one, not too much to see and it seems to have characters on the underside that make it look like a Duskywing...maybe Horace's Duskywing?...lots of oak down below off the west side of Wolf Ck. Pass! And...I did not see the resubmission of the Greenish Blue that was somehow sent to "cannot identify." Mike
