Coordinator notes: This is a tough one! I can only say "female" with confidence. You literally can almost flip a coin to determine a female Northern vs. a female Pearl. To further aid in the ID, a ventral view can also help but is also nonspecific. What I think favors a Northern Crescent for your individual (keep in mind all of these points are VERY nonspecific):
1) Orange-tipped antennae - can be seen in both species, particularly the females.
2) "Two-toned" orange appearance to the dorsal FWs. This can also be seen in either species.
3) A more "open" appearance to the dorsal HW orange patch. The black veins and median/postmedian horizonal bar are less apparent in this individual. Female Pearls usually are completely "barred up" with dark veins and the horizontal bar traversing the orange patch.
4) Location. The further north you go, the more likely you are to get more Northerns. Both species can still be readily found in this part of New York.
Hope this helps! -jmgesell
