  • Spotted Lanternfly Found in Oakland County, Michigan

    • Aug 11, 2022

    • Michigan Department of Agriculture and Rural Development.

    • Today, Michigan Department of Agriculture and Rural Development (MDARD) Director Gary McDowell confirmed the state’s first detection of spotted lanternfly (Lycorma delicatula) in Michigan. A small population of spotted lanternfly was detected in Pontiac in Oakland County last week with the United States Department of Agriculture (USDA) confirming the finding on August 10.

      Spotted lanternfly moves easily on firewood, tires, campers, vehicles and more. Prevention and early detection are vital to limiting the spread of spotted lanternfly. If you find a spotted lanternfly egg mass, nymph or adult, take one or more photos, make note of the date, time and location of the sighting, and report it online to Eyes in the Field. Photos are necessary to verify a report and to aid in identification.

  • Spotted Wing Drosophila

    • Michigan State University. Integrated Pest Management Program.

    • The Spotted Wing Drosophila (SWD) is a vinegar fly of East Asian origin that can cause damage to many fruit crops. This small insect has been in Hawaii since the 1980s, was detected in California in 2008, spread through the West Coast in 2009, and was detected in Florida, Utah, the Carolinas, Wisconsin and Michigan for the first time in 2010. This website will be the central location for dissemination of information about this insect. Check back for updates. This team is also helping to coordinate research projects to understand how best to protect fruit from infestation by this new pest.

  • Two More Invasives to Look for in Michigan

    • Aug 22, 2023

    • Michigan.gov. Michigan Invasive Species Program.

    • Michigan’s invasive species watch list was recently updated to include two new species and remove another. Mountain pine beetle, a deadly threat to pine trees, and water-primrose, a fast-spreading aquatic plant, have been added to the watch list due to threats they pose to native ecosystems and industry. European frog-bit, originally listed in 2011, has been moved off the list of species of immediate concern and is now considered established in the state.
