Of the two Erythroneura species, E. comes is the dominant species in most areas of the Northeast. In contrast to the GLH and E. tricincta, the potato leafhopper does not overwinter in this area. It is an annual migrant from the south and usually appears around mid-June in this region. In some years E. fabae can be more destructive than the GLH.en-USAgricultural IPMFruitsGrapesfact sheet
