Calopteryx maculata

Ebony jewelwing

Unlike every other jewelwing in North America, the ebony jewelwing's wings are completely black from base to tip in both sexes, not just at the tips.

WhenMay to August

Males are metallic blue-green with entirely black wings, while females are a duller bronze-green with smoky brown wings marked by a small white spot near the tip of each one. Both sexes are large, slender damselflies with a slow, fluttering flight low over the water.

Adults are found along shaded, slow-flowing streams and wooded rivers across the eastern United States and southeastern Canada, though they can wander well away from water once mature. Males defend short stretches of stream bank and display to females with a fluttering flight before mating.
