 The Spotted Lanternfly (SLF) is a harmful invasive insect species that is a very real threat to our area. Large populations of SLF are now present in neighboring Pennsylvania and other states where they are causing economic damage. Smaller populations of SLF have been found in other states, including NY where it has been discovered moving towards the Finger Lakes Region. For an updated map of its presence and information on its biology, CLICK HERE.

SLF has been known to feed on as many as 70 different plant species, including plants that are important to the economy of the Finger Lakes, including grapes, apple, and hops. The impact of SLF on our agriculture could be devastating, with hundreds of millions of dollars at stake. SLF also feeds on many of our native tree species, including maples and walnuts that could have a negative impact on the Seneca Lake watershed. SLF is capable of living within a wide range of environments, from forests to farm fields to city landscapes. Expect to find this insect near its preferred host tree, the tree of heaven.

Preventing the spread of SLF is key, and early detection of new populations is critical for control. The Finger Lakes Institutes PRISM folks are now seeking volunteers that are interested in managing SLF traps for this coming season. The below link will take you to a survey and get you tied into this process.
