Adults inhabit fast gravel and rubble riffles of creeks and small to medium rivers (Ref. 5723, 10294); also found in streams (Ref. 10294). Feed on midge larvae, hydropsychid and hydroptilid caddisfly larvae, mayfly nymphs, and fish eggs (Ref. 10294). Distinct pairing during breeding (Ref. 36980). Eggs are found buried in the substrate (Ref. 7043).
