Avoiding applications during the hottest part of the day, when evaporation is highest, will further reduce drift. When high winds and excessive evaporation are not present, a drift retardent may be useful for aerial applications. Using the largest droplet size compatible with the pesticide coverage will reduce drift. Typically, higher spray volumes will also result in less drift. It has russet markings on a field of dark yellow, a prominent double spot on the tail fin, and a dark bar under the eyes.
Male darters are larger than females.
Spawning occurs when the darter is about two years old, and life expectancy is three years. Darter fry hatch at the same time as mayfly larvae emerge and are the young darters primary source of food. Adult darters feed on various insects and plant matter. This species is believed to be endemic to the Bayou Pierre and its five tributaries whose source is a small seep near Brookhaven in Lincoln County, Mississippi. Upstream the habitat is limited by waterfalls and downstream by loss of suitable habitat.
