Chlorocyphidae - Heliocypha biforata

Heliocypha biforata is a beautiful damselfly species. It looks alike H. perforata, yet both the species could be distinguished easily. H. biforata has more intensive pink marking on its dorsal thorax and less obvious blue marking on its abdomen compared to H. perforata. H. biforata and H. perforata share similar habitat (fast flowing forest stream) and have similar behaviour (pearching on logs and rock along the stream).
