Identification
Flattened head and "glassy" wing patches, and head with pale spots on dark ground. Separated from the smoke-tree sharpshooter as shown here.
Range
se. US (TX-FL-NC-AR) & Mexico(1), introduced in sw. US (CA-AZ) (BG data)
Remarks
A major vector of Pierce's disease on grape. Usually not a serious pest within its native range, southeastern US. This species was accidentally introduced into so. California in the early 1990s, probably with ornamental or agricultural stock. There, it has become a serious threat to viticulture.(2)
The biggest problem is that it can spread the disease-causing bacterium Xylella fastidiosa.
The most important biocontrols are egg-parasite wasps in the genus Gonatocerus. Spiders, assassin bugs, and praying mantis prey on the mobile forms.
