Description:

The Black Stream Glider or Indigo Dropwing (Trithemis festiva) is a tropical Asian species normally found at flowing streams with rock and gravel. Mature male Trithemis festiva are entirely dark (i.e. dark blue rather than black) overlaid with a fine whitish pruinescence. Young males look similar to females, sporting extensive yellow patches on their abdomen. In addition, females especially often have extensive dark patches at the wing tips. T. festiva can be distinguished from I. limbata by having orange streaks on its abdomen. Taken at Kadavoor, Kerala, India
