General Description
The range of Promenetus exacuous from Atlantic to Pacific Coasts of North America, from New Mexico, Nevada, and northern Texas to the Arctic-Boreal Transition Zone in Canada (Burch 1989 and Jokinen 1992). It occurs in quiet, shallow areas of lakes and rivers, as well as intermittent or permanent streams and ponds (Clarke 1981 and Jokinen 2005). The only location that we have in the database is for the Red Rock River wetlands refuge in Montana

Range Comments
The range of Promenetus exacuous extends from the Atlantic to the Pacific Coasts of North America, from New Mexico, Nevada, and northern Texas to the Arctic-Boreal Transition Zone in Canada (Burch 1989 and Jokinen 1992).

Migration
Sedentary.

Habitat
It occurs in quiet, shallow areas of lakes and rivers, as well as intermittent or permanent streams and ponds (Clarke 1981, Jokinen 1992, and Jokinen 2005).

Food Habits
Feeding is associated with scraping organic materials (algae, diatoms, etc.) from living or decaying plant matter

Ecology
Substrata occupied include dead or living vegetation, mud, and occasionally rock (Clarke 1981, Jokinen 1992). Promenetus exacuous inhabits both soft- and hard waters (Jokinen 1983, McKillop 1985, and Dillon 2000).

Threats or Limiting Factors
Although P. exacuous occurs in eutrophic systems, it is sensitive to environmental degradation (Clarke 1979).
