Habitat. In Socotra collected only in two mountain localities: the high-montane zone in Hagher Mts. on a small open helocrene with waterlogged vegetation and scattered miniature pools, surrounded by a dense montane evergreen forest at Skand Mt. (1450 m a.s.l.; Fig. 51 ), and in motane zone along a brook at wadi Madar (1180–1230 m a.s.l.; Fig. 50 ).

In tropical Africa, the species lives on various shores ( LINNAVUORI 1981) and it was also collected at light ( LINNAVUORI 1974, 1981; J. T. POLHEMUS 1981). In the Cape Verde Islands, it was found at foot of a wet mountain precipice (1300 m a.s.l.) as well as on bank of a river (ca. 400 m a.s.l.) ( LINDBERG 1959). In Madagascar, it was collected in a small clearing in montane rainforest by flight-intercept yellow pan trap (J. T. POLHEMUS & D. A. POLHEMUS 1991b). In the Seychelles, it occurs in a wide variety of lowland littoral habitats along the margins of streams, marshes and ponds (D. A. POLHEMUS & J. T. POLHEMUS 2013). In Singapore, it was found in wet sandy areas (J. T. POLHEMUS & D. A. POLHEMUS 2012). COBBEN (1987) considered it a pioneer species, often collected in the field and in light traps together with Micracanthia ornatula .
