It is a medium-sized damselfly with bluish green eyes with a tiny black spot on the top, paler below. Its thorax is bluish green on dorsum, and azure blue on the lower sides. There is a very thin and black mid-dorsal carina, bordered with equallynarrow black lines, running close and parallel to it on each side. There is a narrow black humeral stripe and a short black point at the upper part of postero-lateral suture. Winqs are transparent with diamond-shaped pterostigma. Abdomen is azure blue with dorsal black mark up to segment 7. Segments8 to 10 have only narrow apical black lines. Superior anal appendages are azure blue with black tips. Female has dull colored thorax and abdomen, mid-dorsal black stripe extended to the last segment. It breeds in slow flowing marshy streams and lakes in the lowland. Commonly seen along shoreline or on emergent vegetation; seen from hilly areas only during the migration.[2] [3] [4] [5] [6]
