Inhabit fast rocky riffles of creeks and small to medium rivers (Ref. 33799); also found in medium to large streams (Ref. 10294). Adults occur in the deepest portions of riffles with moderately strong current. Prey mainly on insects (midge and other dipteran larvae, mayfly nymphs, and smaller quantities of water mites and caddisfly larvae (Ref. 10294)). Feed by pecking small prey from the surface of rocks (Ref. 33799).
棲息於小溪及小型到中型河川的岩石的快速急流;(參考文獻 33799) 也發現於中等的對大的溪流.(參考文獻 10294) 成魚用一般強的水流出現在急流的最深部分。 獵物主要吃昆蟲 (蚊與水小蝨與石蠶幼生 (參考文獻 10294) 的其他雙翅類昆蟲的幼生，孚游類蛹與較小的量) 。 藉著以喙啄來自岩石的表面的小的獵物覓食。 (參考文獻 33799)
