We had long suspected that this rare emerald was in Vermont — we just hadn’t found it. Until now. Mike Blust and Josh Lincoln discovered S. incurvata on 16 Sept 2017 in Victory, Vermont. Among the rarest North American dragonflies, Incurvate Emerald remains elusive, known only from scattered records throughout the upper Midwest and northeastern North America. We continue to seek out sites in Vermont. Try bogs where Delicate Emerald (S. franklini) flies earlier in the year. Males are usually seen during sunny weather conditions from mid-morning to mid-afternoon (Shiffer 1985). In contrast, females appear to be most active on warm, but overcast, days when very few males are evident.
