That is my best effort identification and the closest match in my book, Dragonflies and Damselflies of Costa Rica, A Field Guide by Dennis Paulson and William Haber. But for those who care about ID, note that this one is very similar to Calvert’s Dancer female and the wings just like the Cerulean Dancer female, though mine here has a darker body and tail. I’m finding Dragon and Damselfly ID pretty difficult as I haven’t learned the subtle differences in body parts yet. 🙂 This one was in my garden the other day.
