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.
