The Bronze Copper at Dead CK was a 'lifer' for me too!   (The ONLY) other butterflies seen besides whites and sulphurs were:

Summer Azures - 2
Monarch  1 at Brookside BB

A note about the sulphurs:   It was a remarkable sight from the viewing area on RT 17.   Hundreds of little yellow sulphurs were flitting low over the purple clover -  very pretty!
