Adults occur in rubble and gravel riffles, less often in sand-gravel runs of headwaters, creeks and small rivers. Also found in springs and their effluents and rocky shores of lakes (Ref. 1998, 10294). They feed mainly on aquatic insect larvae, but also on crustaceans, annelids, fishes, fish eggs, and plant material (Ref. 1998, 10294). Spawn in the spring (Ref. 1998). A male guards the cluster of eggs laid by different females (Ref. 1998). Neither anterolateral glandular groove nor venom gland is present (Ref. 57406).

Madurez | Reproducción | Puesta | Huevos | Fecundidad | Larva
Male selects a nesting site under a rock of ledge. Male entices a female to enter the nest. Female deposits eggs on the upper surface of the rock and leaves or is driven out of the nest. Eggs are deposited by different females. The male guards the eggs from predators and maintains a natural current flow (Ref. 1998). Also Ref. 53335.
