Spotted a beautifully colored damselfly on the Shasta daisies this morning. This is Ebony jewelwing (Calopteryx maculata).
The rich black wings and the metallic blue-green body indicate it is male.
He rested patiently while I took pictures, opening his wings slowly and infrequently (the video is set to loop, so it exaggerates the action).
He lingered awhile longer then gracefully lifted himself away.
