This species is at the eastern edge of its range in New York and the habitat it prefers is rather limited in New York. There are a total of 11 known extant populations. Eleven populations have not been seen in over 55 years and are considered historical. There are 3 populations which are believed extirpated.
No populations are known to have been extirpated in recent years. Most known extant populations occur in habitat that is in good shape although at least one is being threatened by invasive plants. Overall, although short term trends are not clear they appear to be stable to perhaps slightly declining.
Six out of the 11 known extant populations were first documented within the past 25 years. It is likely these populations were simply overlooked in the past and are not truly "new". Around 11 populations have not been seen in at least 55 years. Most of these populations have not been searched for recently and may still be extant. Around 3 populations have become extirpated in the past 100+ years. Overall, long term trends indicate at least some decline.
