The variegated grape leafhopper, the principal pest of grapes in southern California and Arizona, was reported for the first time in 1980 on grapes in Fresno County, in the San Joaquin Valley. Its widespread distribution there, however, suggested that it had been present before then. This leafhopper has since been found also in Tulare County. A closely related species, the grape leafhopper, is the most common grape pest in central and northern California.
