Forewing Scale Features of Spring Azure (C. ladon)

UPDATE:  Richard Orr composed these nicely in a cheat sheet to separate males of ladon and neglecta:

We’ve talked at length in previous posts about males of Spring Azure, Celastrina ladon, having a very distinctive looking “mat” of scales on their dorsal forewings.  This accounts in part for their light violet coloration, and can be seen exceptionally well in these photos shared by Richard Orr of male ladon from the Middle Patuxent Environmental Area in Howard Co. taken earlier this week.
