Spotted Lanternfly ID Webinar

  • Tuesday, February 23, 2021, 1:00 PM - 3:00 PM

NYS is hosting webinars on identifying the invasive Spotted Lanternfly (SLF) and its favorite food, tree-of-heaven. This invader has been found in Tompkins County.

Each webinar will focus on the life stage of SLF at that time of year. The first webinar, February 23 from 1:00 to 3:00 pm, will focus on identifying SLF egg masses. It will cover how to sign up to be a citizen scientist volunteer and how to use iMapInvasives to track data. The training will be offered over WebEx. Register to get the webinar link.

NYS is recruiting volunteers to monitor for spotted lanternfly within a specific area. NYS Department of Agriculture and Markets and the Office of Parks, Recreation, and Historic Preservation have identified 1km grid squares across the state where volunteer survey efforts would be most helpful. These may be close to known infestations, along major pathways, and/or near important commodities that could be harmed by SLF. The grids are in areas where there is public access.
