Family: Loopers, Span Worms, Inch Worms, Geometer Moths (Geometridae)

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

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?
The foodplant of the larva was once so common that it was commercially important as New Jersey Tea, especially around the time of the American Revolution. Now the plant is so reduced that this moth, another related species, and a skipper butterfly whose larvae feed on the leaves of the same plant are probably gone from New Jersey, most of New York, and neighboring states. The Albany Pine Bush is probably the only place in the Northeast where all three still occur. Excessive browsing by deer and loss of brushy and barrens habitats are among the factors in this decline.

State Ranking Justification [-]
In the last few decades, the broad-lined catopyrrha was known to occur only in the Albany Pine Bush and possibly in Saratoga County. This species was formerly much more widespread than it is now. Like other New Jersey Tea (Ceanothus americanus) specialists, the Broad-lined Catopyrrha has become very rare or disappeared in all neighboring states. Outside of New York, only two other occurrences are known to be extant east of Ohio. White-tailed deer (Odocoileus virgineanus) are a threat at the known locality and have reduced the foodplant there to some extent.
