Occurs in rocky riffles and runs of medium to large rivers. Often found near vegetation (Ref. 5723, 10294). Feeds on hydropsychid caddisfly larvae, ephemerellid mayfly nymphs, and blackfly and midge larvae (Ref. 10294).
出現於中型到大型河川的岩石的急流與小支流。 時常在植物的附近發現。 (參考文獻 5723,10294) 吃 hydropsychid 石蠶幼生， ephemerellid 孚游類蛹與黑蠅與蚊仔魚。 (參考文獻 10294)
