Flatwing Damselfly, Pavones, Costa RicaI believe this guy to be of the species Heteragrion erythrogaster — a flatwing damselfly. He/she was being very cooperative, so I used a tripod with a very slow shutter speed of nine seconds. Photographed by the side of a waterfall in the town of Pavones in southwestern Costa Rica. Nikon D200 with Nikkor 70-200mm lens (at 200mm with Canon 500D close up filter) ISO 100, f/22 at 9 seconds.
