Spotted lanternfly is a newly invasive pest that has been found in several eastern states. Feeding activity and copious honeydew production can damage vines and fruit trees and promote the growth of sooty mold.
There is great potential for dispersal of this insect from the eastern US to other regions, given that females will lay eggs on a variety of inanimate objects (pallets, outdoor equipment, railway cars) that may be moved large distances.

Vigilance and efforts to identify early invaders are critical to a successful response, should this pest be introduced to California. Report sightings and bring suspicious specimens to your local Agricultural Commissioner's office for confirmation.
