Occurs in various habitats, but most common in rocky riffles and runs of clear mountain creeks and small to medium rivers. Rarely found in lakes (Ref. 1998). Feeds on diatoms, other algae, higher plants, dipterous larvae and pupae (Ref. 1998). Spawning adults may be preyed upon by birds and mammals while small individuals may be preyed upon by stream salmonids (Ref. 1998). Edible.
