A map identifying the areas suitable for establishment of the spotted lanternfly (SLF) in the United States and other countries has been published in the Journal of Economic Entomology by Agricultural Research Service scientists. The SLF, originally from China, has spread to Korea and Japan, and has been found most recently in the United States in Pennsylvania, New Jersey, Virginia and Delaware. These insects are pests of many agricultural crops including almonds, apples, blueberries, cherries, peaches, grapes and hops as well as hardwoods such as oak, walnut and poplar, among others. USDA and State partners have been working to contain SLF populations since 2014. There is the potential for far reaching economic damage if the SLF becomes widely established in the United States.

The Delaware Department of Agriculture (DDA) announced today that they expanded the spotted lanternfly quarantine to include all portions of New Castle County north of the Chesapeake and Delaware Canal. This is due to recent detections of established populations outside of the initial quarantine zone enacted in February 2019 that included eleven zip codes. "This expansion is necessary in our attempt to eradicate, control, and prevent the spread of spotted lanternfly in Delaware and to surrounding states," said Secretary of Agriculture Michael T. Scuse. The spotted lanternfly is a destructive invasive plant hopper that attacks many hosts including trees, shrubs, orchards, grapes, and hops. For more detailed information regarding the quarantine, permitting, treatment, or to report a sighting of spotted lanternfly, visit the Delaware Department of Agriculture’s dedicated spotted lanternfly webpage or call the dedicated spotted lanternfly hotline at (302) 698-4632.

Spotted lanternfly is a threat to Maryland and the U.S. The Maryland Department of Agriculture issued a quarantine October 28, 2019 in an effort to contain the invasive species in Cecil and Harford counties after the spotted lanternfly was spotted in Cecil’s northeastern corner and along Harford’s northern border. See additional resources on the Maryland Department of Agriculture's site for Spotted Lanternfly for up-to-date information.

The Connecticut Agricultural Experiment Station (CAES) in cooperation with USDA APHIS Plant Protection and Quarantine (PPQ) announce the detection of single live adult spotted lanternfly, Lycoma delicatula, in Southbury, CT. While no other spotted lanternflies were found upon surveying the immediate area, a live insect strongly suggests others may be present within easy transport from somewhere in the region. Additional surveys in the area are planned.

The spotted lanternfly is an invasive sap-feeding planthopper that was discovered in Berks County, Pennsylvania in 2014. It is native to China, India, and Vietnam. It attacks many hosts and has the potential to severely impact Connecticut’s farm crops, particularly apples, grapes, and hops, as well as a number of tree species like maple. Early detection is important for the protection of Connecticut businesses and agriculture. The public is urged to report potential sightings of this invasive pest to ReportSLF@ct.gov. For more information, see the CAES Pest Alert [PDF, 1.9 MB].

The Maryland Department of Agriculture has confirmed that a single adult spotted lanternfly has been found on a trap in the northeast corner of Cecil County near the border of Pennsylvania and Delaware. This is the first confirmed sighting of the invasive species in Maryland, and the department does not believe there is an established population of the pest in the state. If you suspect you have found a spotted lantern fly egg mass, nymph, or adult, snap a picture of it, collect it, put it in a plastic bag, freeze it, and report it to the Maryland Department of Agriculture at DontBug.MD@maryland.gov.

The spotted lanternfly, first sighted in Pennsylvania, is an invasive pest to the U.S. See this photo essay to learn more about ARS's research efforts.

The Massachusetts Department of Agricultural Resources (MDAR) announced today that a single dead specimen of the invasive pest known as spotted lanternfly (Lycorma delicatula) was reported and confirmed at a private residence in Boston. As a result, MDAR is urging the public to check for signs of spotted lanternfly adults in any potted plants that they may have received over the holiday season and to report any potential sightings of this pest on MDAR's online reporting form by taking photographs and collecting a specimen if possible. Residents should look for large, gray insects, about one inch long, with black spots and red underwings.

The Maryland Department of Agriculture (MDA) expanded its spotted lanternfly quarantine.  A quarantine order first issued by the state secretary of agriculture in October 2019 for Harford and Cecil counties is still in effect, but has been expanded this year to also include: Anne Arundel, Baltimore, Carroll, Frederick, Howard, Kent, Montgomery and Washington counties, as well as Baltimore City. This quarantine is effective immediately, and restricts the movement of regulated articles that might contain the spotted lanternfly in any of its life stages, including egg masses, nymphs, and adults.

See additional resources on the Maryland Department of Agriculture's site for Spotted Lanternfly for up-to-date information. For questions related to the quarantine, permitting, treatment, or to report a sighting of the spotted lanternfly, especially outside of the quarantine zone, call 410-841-5920 or email DontBug.MD@maryland.gov. If you report a spotted lanternfly via email, please provide the location of the sighting and your contact information.

Have you recently planted maple, crabapple, or other trees? MDAR is asking everyone to check them for spotted lanternfly egg masses or recently hatched nymphs after we were alerted that trees or shrubs with SLF egg masses may have been recently shipped to Massachusetts. Please give all nursery stock a thorough check (including pots or other containers), especially if the plants have tags that indicate they are from Pennsylvania, New Jersey, or other SLF-infested states, and report any finds.

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 Spotted Lanternfly Reporting Tool.

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 Vermont Agency of Agriculture, Food and Markets is asking the public to keep an eye out for the invasive pest known as spotted lanternfly (Lycorma delicatula) during the spring landscaping season. This is due to the risk of egg masses being accidentally brought in on shipments of nursery stock imported from other states that may have an established spotted lanternfly (SLF) infestation. This invasive bug is not yet known to have established a breeding population in Vermont. If you see any signs of spotted lanternfly, please report it. The Agency may contact you to determine if action is necessary to prevent establishment in Vermont.

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 Maryland Department of Agriculture expanded its spotted lanternfly quarantine to include a total of 17 counties and the city of Baltimore. The quarantine is effective immediately, and restricts the movement of regulated materials that might contain the spotted lanternfly in any of its life stages, including egg masses, nymphs, and adults.
