Inhabit shallow gravel riffles, sometimes rocky runs and pools, of headwaters, creeks and small rivers (Ref. 5723); also found in streams (Ref. 10294). Adults feed on midge and blackfly larvae, mayfly nymphs, isopods, amphipods, and caddisfly larvae (Ref. 10294). Distinct pairing during breeding (Ref. 36980).
