Barrens Dagger Moth Canadian Biodiversity Information Facility (CBIF)
Family: Owlet Moths (Noctuidae)

State Protection: Not Listed
The species is not listed or protected by New York State.

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: G3G4
A Global Rarity Rank of G3G4 means: Vulnerable globally, or Apparently Secure -- At moderate risk of extinction, with relatively few populations or locations in the world, few individuals, and/or restricted range; or uncommon but not rare globally; may be rare in some parts of its range; possibly some cause for long-term concern due to declines or other factors. More information is needed to assign a single conservation status.


Did you know?
The Barrens Dagger Moth needs habitat patches at least 1,000 acres in size and most patches where this species occurs are between 2,000 and 10,000 acres.

State Ranking Justification [-]
The Albany population is very likely to be extirpated, since there has been no evidence of this species in many years, despite over two decades of survey effort, and therefore was considered historical in the state. The state rank was changed after a single individual was captured in the dwarf pine barrens of Long Island in 1999, suggesting that a population is present in the vicinity of the capture location. Additional records for this species are all pre-1900. The precise habitat is poorly understood, which makes locating it in places where general pine barrens vegetation is somewhat widespread, like on Long Island, difficult.
