Adults inhabit rocky riffles, runs and pools of clear creeks and small rivers. Occasionally found in large rivers and impoundments (Ref. 5723, 10294). They feed on immature stages of benthic insects and snails (Ref. 10294). They feed by disturbing the stream bottom with its large snout and sucking up organisms that it dislodges (Ref. 84357).
