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: GUT1Q
A Global Rarity Rank of GUT1Q means: Critically Imperiled globally - The subspecies/variety is at very high risk of extinction due to extreme rarity or other factors; typically 5 or fewer populations or locations in the world, very few individuals, very restricted range, very few remaining acres (or miles of stream), and/or very steep declines. (The species as a whole is currently unrankable due to lack of information.) The Q indicates this subspeciesí or variety's status as a distinctive taxonomic entitity is uncertain.

Some small fruit fly species (Tephritidae) may depend on the larvae of this moth, which, in turn, depend on northern gama grass (Tripsacum dactyloides) (Bird 1913; Kunstler 1991).
