Species of true bug
Graphocephala atropunctata, commonly known as the blue-green sharpshooter, is a hemipteran bug native to the United States west coast,[1] as well as Arizona and New Mexico. It carries the phytopathogenic bacteria Xylella fastidiosa which infects the xylem of grape vines causing die-back – known as Pierce's disease. This leads to loss of productivity and economic damage to the California vineyards.[2]
