Sparta Mountain WMA, Sussex County, New Jersey, USA June 21, 2014
I feel like this has to be a worn swallowtail, but for some reason I can't find this pattern (blue and orange, no yellow) in any of my books or on the guide pages. I think as soon as someone IDs it I'm going to turn to the right page and it's going to be staring me in the face, but for now I'm stumped.
