Pseudagrion decorum,[2][1] elegant sprite or three striped blue dart,[3][4] is a species of damselfly in the family Coenagrionidae. It is found in many tropical Asian countries.[1][5]

Description and habitat

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 equally narrow 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. Segments 8 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.[6]

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.[6][7][8][3][4]
