Did you know?
The word incurvate means to curve inward. The Incurvate Emerald is so named because the claspers (terminal appendages) on adult males curve inward at the tip from the dorsal (top) view (Jones et al. 2008).

State Ranking Justification [-]
In New York, Somatochlora incurvata is known from four bogs in three counties in the North Country (New York Natural Heritage Program 2017). It has a small known range in the state, limited to Adirondack sphagnum bogs where threats to habitats could include climate change and hydrologic alteration due to human activities.
