Glassy-winged sharpshooter (Homalodisca coagulata) is a serious new pest in California. It is a particular threat to California vineyards due to its ability to spread Xylella fastidiosathe bacterium that causes Pierce's disease. Pierce's disease kills grapevines, and there are no effective treatments for it.

Second generation eggs masses are laid starting in mid-June through late September, which develop into over-wintering adults.
