Spotted lanternfly (Lycorma delicatula; SLF) is an invasive insect pest that feeds on over 70 economically and ecologically important species such as grapes, apples, and hops. SLF’s favorite tree to lay its eggs on is tree of heaven (Ailanthus altissima; TOH), a very widespread invasive tree.

Spotted lanternfly has now been reported numerous times within Staten Island, Brooklyn and Queens. By fall of 2021, SLF was as well found within Nassau County, and as far east in Suffolk County as Connetquot State Park and McArthur Airport.
