  Distribution. –  Widespread the Oriental and Australasian realms. From India, Thailand, Vietnam, West Malaysia, Indonesia, New Guinea, Australia and Fiji (Hebauer, 1995b; Hansen, 1999), Singapore (Balke et al., 1999).   
  Ecology. –  One of the most common species of the family in Southeast Asia and often attracted to light. Its flight is often associated with heavy rains and colonises a wide variety of haitats (Fernando, 1961; Yano et al., 1983a). It is mainly a lentic species living in very shallow water at the edge of small, exposed and weedy pools, puddles and slow flowing streams and ditches.
