Homalodisca liturata
smoketree sharpshooter, lacertate sharpshooter
Homalodisca liturata, commonly known as the smoketree sharpshooter or lacertate sharpshooter, is a relatively large leafhopper species native to North America, measuring approximately 13 mm in length. The species exhibits strong host-plant associations, with documented preference for desert smoketree (Psorothamnus spinosus) where available, though it utilizes multiple host species. H. liturata is a known vector of Xylella fastidiosa, the bacterial pathogen causing Pierce's disease in grapevines and other plant diseases. Both sexes produce acoustic signals, a notable behavioral trait among sharpshooters. The species has been documented harboring phytoplasma bacteria related to 'Candidatus Phytoplasma hispanicum' in its salivary glands, suggesting potential involvement in transmitting yellows-type diseases.
