Inhabit clear, fast rocky riffles of creeks and small to medium rivers (Ref. 5723); also found in streams (Ref. 10294). Adults feed on midge and blackfly larvae, with baetid and heptageniid mayfly nymphs, hydropsychid and hydroptilid caddis larvae, and water mites (Ref. 10294). Eggs are found buried in the substrate (Ref. 7043).
