Confidence: I'm as sure as I can be.
Notes: Slim and elegant this pale blue damselfly is usually identified by the black “u” symbol located on the second abdominal segment. The 8th abdominal segment is pale blue; segment 9 has pale blue background with another truncated black “u” at its base. The upper surface of the thorax in front of the wings is marked with fine (antehumeral) stripes. Immature males exhibit all the above black markings with pale violet pigmentation that will become blue with sexual maturity.
