State Rarity Rank: S2S3
A State Rarity Rank of S2S3 means: Imperiled or Vulnerable in New York - Very vulnerable to disappearing from New York, or vulnerable to becoming imperiled in New York, due to rarity or other factors; typically 6 to 80 populations or locations in New York, few individuals, restricted range, few remaining acres (or miles of stream), and/or recent and widespread declines. More information is needed to assign a single conservation status.

Global Rarity Rank: G5
A Global Rarity Rank of G5 means: Demonstrably secure globally, though it may be quite rare in parts of its range, especially at the periphery.


Did you know?
Most species of Striped Emeralds, dragonflies of the genus Somatochlora, have a metallic green wax coating their thorax (Dunkle 2000). The females of our species of interest, the Mocha Emerald, are slightly larger than the males (Natural Heritage Endangered Species Program 2003).

State Ranking Justification [-]
The Mocha Emerald is known to occur in eight counties in New York State, with no population estimates determined. Further survey efforts may result in the identification of additional populations or range expansions, and may enable population size estimations.
