Distribution and biology. Males have been collected in Malaise traps sampled from January through August across western Madagascar. Habitats in which this species was collected include the spiny bush near Fort Dauphin, dry forest in Kirindy near Morandava, rainforest in the Sambirano region on the Ampasindava Peninsula, and coastal scrub on sand dunes near Antiranana in the northeastern tip of Madagascar. The nesting habits of Ravavy are not known.
