Special needs

Spawn in lakes. Also inhabit marshes or rivers. Adults are smaller than late-stage larvae, possibly because of difficulty finding food, yet still can spawn. Adults parasitic; potential role of reducing egg predators.

Limiting factors

Altered hydrology and flow regime. High mortality and concentration of eggs in small area.

Conservation actions

Implement conservation plan adopted by ODFW in summer 2005. Also, increased understanding of biology will help in identifying habitat requirements and potential conservation actions. Remove barrier on Miller Creek.
