Coordinator notes: I believe your suggest ID is correct though it is a very late record for this species. It is a female and it doesn't appear to be the other possible species, Erynnis horatius on which females have a larger more prominent dark patches on the upper forewings. Update - the original date of 9/5/2020 was a mistake and has been changed to 7/5/2020.
