Common name: Johnny Darter
available through www.itis.gov
Identification: Becker (1983); Page (1983); Page and Burr (1991); Etnier and Starnes (1993); Jenkins and Burkhead (1994).
Size: 7.2 cm.
Native Range: St. Lawrence-Great Lakes, Hudson Bay, and Mississippi River basins from Hudson Bay to southern Mississippi, and from Quebec and Virginia to Saskatchewan and Colorado; on Atlantic Slope in James, Roanoke, Tar, and Neuse River drainages, Virginia and North Carolina; on Gulf Slope in Mobile Bay drainage, Alabama and Mississippi. Absent in White River drainage (Arkansas and Missouri), most of Arkansas River drainage, upper Tennessee River drainage, and middle Cumberland River drainage (Page and Burr 1991).
This species was collected in the Colorado River from Lake Granby and Shadow Mountain Reservoir (Tyus et al. 1982) in Grand County and from Montezuma County, Colorado (Woodling 1985; Page and Burr 1991). Propst and Carlson (1986) reported that G. T. Baxter (University of Wyoming) believes that the Johnny Darter was not native to the North Platte drainage in Colorado. It has also been collected from the Lake Sakakawea drainage in McKenzie, McLean, and Williams counties, and Square Butte Creek in Oliver county, North Dakota.

† Populations may not be currently present.
Ecology: Occupies sandy, muddy, or rocky areas of small and large streams, creeks, pools, reservoirs, and lakes (Propst and Carlson 1989; Page and Burr 1991). Prefers slow water over sand/gravel substrates, but has a wide range of environmental tolerances (Propst and Carlson 1989). Primarily consumes chironimid and other insect larvae (Propst and Carlson 1989).
Means of Introduction: Unknown.
Status: Reported from Colorado and North Dakota.
Impact of Introduction: The impacts of this species are currently unknown, as no studies have been done to determine how it has affected ecosystems in the invaded range. The absence of data does not equate to lack of effects. It does, however, mean that research is required to evaluate effects before conclusions can be made.
