Recorded from a considerable range of hosts and, when abundant, damages pasture grasses by its feeding.
G. nigrifrons is one of the most common and ubiquitous leafhoppers in the US and Central America (Kramer, 1967). It is the primary vector of maize chlorotic -dwarf virus but not considered an important rice pest, although frequently collected from rice. G. nigrifrons has been the subject of considerable research in the USA in the past 20 years.
