Description and habitat

It is a small dragonfly with brown-capped yellowish-green eyes. Its thorax is olivaceous-brown, marked with a reddish-brown humeral stripe and two brownish stripes on each side. Wings are transparent; but with a broad bright orange fascia extending from base to within 2 to 3 cells of reddish pterostigma. Abdomen is ochreous-red, marked with dorsal and sub-dorsal brown stripes. Anal appendages are in reddish-brown. Female is similar to the male; but in pale yellowish-green color. Wings are transparent, tinted with yellow at extreme base;, but the bright orange fascia seen in the male absent.[7]

It breeds in weedy ponds, lakes, and slowly moving streams; especially in sluggish waters. It is very common along sewage canals, tanks, ponds and ditches.[7][8][9][3][4]
