Blue-green Sharpshooter

The blue-green sharpshooter (Graphocephala atropunctata) is an insect native to California. It can be distinguished by its bright green-blue wings and its yellow underside. This species grows to be nearly 0.4 inches long and can be found in coastal areas near riparian habitats. Unfortunately for wine makers, it carries a bacteria that causes Pierce’s Disease in grapes, leading to the death of the entire vine. It is fought as a pest in commercial vineyards.
