(Edited) Initially I couldn't get this one. Thanks for help. Some seemed close, such as Celithemis amanda, but not quite right. For example on that one, comparing to descriptions and other BG images, abdomen has almost no brown, head is yellow behind eyes. Also the semi-transparent reddish strips in wings. Anal loop does not seem very similar to other images. I added a second image with my interpretation of triangles and loop, which of course may be completely wrong. It flew before I could get a better angle for wings.
