Spotted lanternfly (SLF; Lycorma delicatula) is an invasive planthopper native to Southeastern Asia and is currently a problematic invasive pest in South Korea. It’s first known North American establishment was in Berks County, Pennsylvania, USA in September 2014. Currently, intense management efforts including quarantine zones and intensive public awareness detection surveys and eradication are underway in several states including New York.  SLF has yet to be detected in Canada.

The adult insect feeds primarily on the non-native tree, tree of heaven, although nymphs are known to attack a wide range of native hardwood and fruit trees. Grape vines are a preferred host of the spotted lanternfly. If this species continues to establish itself in the United States and spreads to Canada, it could be a formidable threat to various industries and the economy – of special concern for the fruit orchard and grape product industries.
