Where are GWSS from?
The glassy-winged sharpshooter was first detected in California near Irvine in 1989 and was later identified by the California Department of Food and Agriculture as a species common to the southeastern United States. It’s previously described native range includes Florida, Georgia, North Carolina, South Carolina, Mississippi, Alabama, Texas, Missouri and Arkansas and northern Mexico. It is thought to have been established in southern California since about 1990, where it may have arrived as eggs on plant material.
