      Ecology: Dolichopodid adults are commonly known as the ‘long-legged flies’.
      Instream habitat: Larvae are found in sand or mud and amongst rotting vegetation and snags in springs, slow-flowing rivers, especially slackwaters, and in ponds.In other countries, Dolichopodidae species are common in rice fields where they thrive in the shallow, nutrient, rich standing waters.
      Feeding ecology: Larvae are thought to be predacious upon small arthropods and oligochaetes. However some species are leaf-miners in aquatic macrophytes and so may be herbivores.
