The glassy winged sharpshooter is a leafhopper from the insect family Cicadellidae. Originally from northeastern Mexico, these little buggers have migrated to the U.S. where they spread Pierce’s Disease, a bacterial infection that kills grapevines.
Voracious eaters, they spread bacteria from plant to plant by inserting their needle-like mouth parts into the xylem of the plant. As they’re eating away, they deposit waste, often dubbed “leafhopper rain”, which can give the leaves and fruit a whitewashed appearance.
Fantastic name for a fantastic pest.
