Biology

Adults inhabit gravel and rubble riffles and adjacent pools of clear, fast creeks and small to medium rivers (Ref. 205); common in cool, clear streams with rocky substrates. Feed on mayfly nymphs and other aquatic immatures, with some terrestrial insects during spring, while summer food consists mostly of insects taken at the surface, with aquatic immatures (Ref. 10294). Oviparous (Ref. 205), probably nest spawners like congeners (Ref. 5723).
