Heterocampa varia Walker, 1855
Family: Prominent Moths (Notodontidae)

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: S1S2
A State Rarity Rank of S1S2 means: Critically Imperiled or Imperiled in New York - Especially or very vulnerable to disappearing from New York due to rarity or other factors; typically 20 or fewer populations or locations in New York, very few individuals, very restricted range, few remaining acres (or miles of stream), and/or steep declines. More information is needed to assign a single conservation status.

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?
This species lives in habitats where hot fires can be common. The open oak scrublands where this species lives are "pyrogenic," meaning they require frequent fire to exist. Pupae of this species are found several inches deep in the ground, and they may overwinter there for three years. Thus, there is always a reservoir of pupae safe from even the hottest forest fires.

State Ranking Justification [-]
In New York State, this species is known only from the dwarf pine barrens on Long Island. Future inventory may locate this species at other pine barrens type habitats on Long Island. This species is ecologically fragile and could experience severe decline if fire suppression allows occupied habitat to transition to oak woods through the process of natural succession.
