Spot and Squash September

Since it was first spotted in New York City in 2020, the Spotted Lanternfly (Lycorma delicatula) has quickly multiplied and become a significant threat to many economically and culturally significant plants such as grapevines (Vitis spp.), stone fruits (Prunus spp.), and Maple (Acer spp.). Adults will begin laying egg masses in September, which will overwinter to hatch next spring. You can help by documenting where these egg masses are located, and by destroying them to prevent further infestation.
