Thorax: Shining black with two pale grass green stripes. Sides are light green and white below. Legs: Pale greenish white with vertical stripe on femur, just above femur - tibia joint. Wings: Transparent. Wing spot: The wing spots are different in fore and hindwings. It is rose-red in forewings and uniform pale grey in hindwings. Abdomen: Bright reddish yellow. The second and seventh segments has upper narrow and broad black marks respectively.[1] Only 1/3 of length of segment 8 and full length of segment 9 tergite are blue. The base color of the segment 8 tergite is melanic black.[6]

Female

Eyes: Brown half moon like cap above, green to pale green below. Thorax: Shining black with two orange stripes. Sides are pale green. Legs: Pale white with vertical black stripes on femur, just above femur - tibia joint. Abdomen: A broad black stripe runs along the upper side of abdomen. Segments 8 - 10 do not have azure blue markings.[1]

Habitat[]

Found among vegetation along the banks of ponds, rivers, canals, marshes and wet rice fields.[1]

Distribution[]

Distributed from Australia, Pacific Islands, East Asia and Southeast Asia.[1] There are strong differences in DNA between the Asian forms of the species and specimens from the Pacific.[1] The form found in Indian subcontinent and Iran is Ischnura aurora rubilio Selys, 1876 and is now considered as a different taxon, Ischnura rubilio.[7]
