I think this is a tiny Sprite damselfly (Nehalennia sp.), but not sure which species exactly. According to my guide there are only two Sprite species around these parts: Sedge Sprite (Nehalennia irene) and Sphagnum Sprite (Nehalennia gracilis). Anyway, it's definitely tiny! Photo taken at the Montreal Botanical Garden.
Pentax D-FA 100mm F/2.8 Macro plus Raynox DCR-250, with off-camera diffused Yongnuo YN560 III flash. MFD, plus a mild crop (~20MP from a 24MP original). Pulled up the exposure quite a bit on this one...
