State Protection: Species Of Special Concern
A native species at risk of becoming Threatened; does not qualify as Endangered or Threatened, but have been determined to require some measure of protection or attention to ensure that the species does not become threatened. NYSDEC may regulate the taking, importation, transportation, or possession of any Species of Special Concern as it deems necessary.

Federal Protection: Not Listed

State Rarity Rank: S1
A State Rarity Rank of S1 means: Typically 5 or fewer occurrences, very few remaining individuals, acres, or miles of stream, or some factor of its biology makes it especially vulnerable in New York State.

Global Rarity Rank: G5
A Global Rarity Rank of G5 means: Demonstrably secure globally, though it may be quite rare in parts of its range, especially at the periphery.

Did you know?
The foodplant of the Henry's elfin is unknown in New York. Blueberry species have been reported, but not officially documented. Hollies and invasive buckthorn are other possibilities.

State Ranking Justification [-]
The status of this species is poorly known in New York. There are former records from the Albany Pine Bush from the late 1800s until the late 1970s, and one record from 1984, but there is little chance that a population of this species is there now, especially since this in not a pine barrens species and the actual location for the 1984 observation was not made in appropriate habitat. With no additional records in such a commonly visited location, plus the fact that fires may impact the species, it is considered historical at that site and therefore in the state. This species cannot adequately be inventoried until the specific habitat requirements are identified for New York and it is possible that populations may be found in northern New York and on Long Island in the future. If this species is rediscovered in New York SU would probably be appropriate.
