Spotted Lanternfly

They’re coming to get you, spotted lanternflies and Japanese beetles! Detector canines—trained by USDA's Plant Protection and Quarantine (PPQ) program—are ready to sniff out these damaging invasive pests to detect them early and prevent their spread. These highly trained dogs represent some of the recent successes of our Agricultural Detector Canines strategic initiative. Its goal is to expand the use of detector dogs to enhance domestic pest surveys, detect pests early, and facilitate the trade of U.S. agricultural products.

The Iowa Department of Agriculture and Land Stewardship asks Iowans to be on the lookout for spotted lanternfly insects. The colorful but invasive and destructive insect is native to China, India, and Vietnam, and was accidentally introduced into Pennsylvania in 2014. It has since been confirmed in eleven states and often spreads by the movement of infested material or items containing spotted lanternfly egg masses. If allowed to spread further in the United States, this pest could seriously impact the country’s grape, orchard, nursery, and logging industries.

A community member notified the Iowa Department of Agriculture and Land Stewardship of the presence of two immature spotted lanternflies in Dallas County earlier this month. Federal identification confirmed the sample as a spotted lanternfly. Surveys of the immediate area have not resulted in signs of an ongoing infestation and entomologists hope the insects recently hitchhiked into the area.

If you think you have found a spotted lanternfly, please call the Entomology and Plant Science Bureau at 515-725-1470 or e-mail Entomology@IowaAgriculture.gov. You may also contact your local county Iowa State University Extension Office.

The North Carolina Department of Agriculture and Consumer Services has confirmed the first established presence of the invasive spotted lanternfly (Lycorma delicatula) in the state. Initial surveys indicate the known distribution of the pest is within a 5-mile radius in Forsyth County near Interstate 40 in Kernersville extending to the Guilford County line.

Early detection and rapid response are critical in the control of spotted lanternfly and the Plant Industry Division has been preparing to provide the most effective response to slow the spread of this invasive pest in the state. If you see or suspect spotted lanternfly in North Carolina submit a picture through the online reporting tool at ncagr.gov/slf.

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.

The Massachusetts Department of Agricultural Resources (MDAR) today announced that an infestation of the invasive insect known as spotted lanternfly (SLF) was found in the City of Springfield last week. "With new populations of the spotted lanternfly likely to pop up more and more frequently as the invasive pest becomes established across the northeast, it is critical that we all remain diligent in identifying them early onAnyone who sees this pest is asked to report it promptly. Early detection will help limit the spread of spotted lanternfly and give orchards, farms, and other growers time to prepare."

Anyone who has recently received goods or materials from states where SLF is known to have been introduced (including Connecticut, Delaware, Indiana, Maryland, New Jersey, New York, Ohio, Pennsylvania, Virginia, and West Virginia; see SLF-infested states) should also be on the lookout. Additionally, if a spotted lanternfly is found, the public is asked to take a photo or collect the specimen, and report the sighting using MDAR’s SLF online reporting form.

The U.S. Department of Agriculture’s Animal and Plant Health Inspection Service (APHIS) has completed a supplemental environmental assessment (EA) required under the National Environmental Policy Act for its spotted lanternfly program. The previous EA for the spotted lanternfly program was finalized in June 2020 and included control and monitoring activities in the mid-Atlantic Region, Kentucky, North Carolina, and Ohio.

The spotted lanternfly may occur on a variety of plant species, including tree-of-heaven, grapevine, stone fruits (apricot, cherry, nectarine, peach, and plum), and other tree species (apple, oak, pine, poplar, and walnut). If allowed to spread, this pest may be harmful to grape, apple, peach, stone fruit, and logging industries. APHIS is publishing the supplemental EA at https://www.regulations.gov/ and on the APHIS's website - Spotted Lanternfly Control Program in the Mid-Atlantic Region, North Carolina, Ohio, and Kentucky [PDF, 2.5 MB].

A state exterior quarantine has been declared to prohibit the introduction of the spotted lanternfly (SLF), Lycorma delicatula, into California. Spotted lanternfly was first detected in North American in 2014 in Pennsylvania and has now spread to nine states. The quarantine prohibits the entry into California of SLF, its host plants, and a variety of articles, including conveyances, originating from any area where an SLF infestation exists.

If you believe you have seen the spotted lanternfly, please contact CDFA's Invasive Species Hotline at 1-800-491-1899, via Report a Pest, or by contacting your local County Agricultural Commissioner.

A 4-H student presenting a project at the Kansas State Fair has inadvertently triggered a state and federal investigation into a nasty, unwelcome bug. The student found the spotted lanternfly in Thomas County in western Kansas and included it in a 4-H entomology display.
