Did you know?
In New York, the northern oak hairstreak occurs in the lower Hudson Valley and on Long Island. It has likely been extripated from the Ithaca area since 1970.

State Ranking Justification [-]
Since the potential habitat is widespread in southeastern New York, and since the species probably spends most of its time in the canopy, it is probably much less rare than records indicate. Nevertheless, the habitat is spotty in heavily developed southeastern mainland New York, although the species could be more widespread on outer Long Island.
