Inhabit rocky riffles of creeks and small to medium rivers, and shores of large lakes (Ref. 5723, 10294). Juveniles feed on midge larvae and microcrustaceans; adults consume midge larvae, blackfly larvae, and other immature aquatic insects, primarily mayflies and caddisflies (Ref. 10294). Distinct pairing during breeding (Ref. 36980). Eggs are found attached to the substrate unguarded (Ref. 7043).
