Family: Metalmarks (Riodinidae)

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 metalmarks are a diverse family of butterflies that mainly occur in the tropics. The northern metalmark is the only species of this family that occurs in New York. Unlike almost all other butterflies, metalmarks often rest flat against the undersides of leaves with the upper surface visible. The metalmark's contrasting orange underside may serve to startle or confuse predators, similar to the colorful hindwings of underwing moths (genus Catocala).

State Ranking Justification [-]
This species has been recorded in only one county (Dutchess) in recent years (2007). The only other documented population statewide was based on collections in Orange County before 1866. None were reported in the state since the 1860s until the 2007 discovery. This species is globally uncommon to rare and it is very rare in New York.
