Cuerna yuccae
Yucca Sharpshooter
Cuerna yuccae is a sharpshooter leafhopper in the family Cicadellidae, first described by Oman & Beamer in 1944. It belongs to the tribe Proconiini, a group known for their role as vectors of plant pathogens including Xylella fastidiosa, the bacterium causing Pierce's disease in grapevines. The species is associated with yucca plants and occurs in arid and semi-arid regions of the southwestern United States. Like other proconiine sharpshooters, it feeds on xylem fluid and has potential significance in plant disease epidemiology.
