The Spotted Lanternfly is an invasive species that destroy fruit crops, trees and plants by hopping from plant to plant, crop to crop, and tree to tree. Although native to regions in China, India, and Vietnam, it was first detected in Berks County, Pennsylvania in 2014. Since then, Pennsylvania vineyards have seen considerable damage in high infestation areas and the Mid-Atlantic states of Delaware, Maryland, New Jersey, Virginia and West Virginia have also suffered from its presence. Insecticides are effective at killing the insect on grapevines, but they are expensive and of limited use because of constant re-infestation from the Spotted Lanternfly dispersing from wild hosts to surrounding vineyards. So, U.S. Department of Agriculture Scientists Dr. Tracy Leskey and Dr. Laura Nixon of the Appalachian Fruit Research Station in Kearneysville, West Virginia, initiated research on the invasive pest to see if they could develop sustainable pest management strategies and use the insect's dispersal patterns for other prolific specialty crop pests.

The Maryland Department of Agriculture has confirmed the first spotted lanternfly hatch of 2020. The first instar nymph of the season was reported by a department employee while surveying for the pest in the upper northeast corner of Cecil County near the Pennsylvania border.

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.

Agricultural Research Service (ARS) scientists, in cooperation with Pacific Biosciences and Penn State University have successfully reconstructed the genome of spotted lanternfly, paving the way for understanding it's biology and behavior. Not only is it the first published genome for this pest, but no closely related species has had its genome sequenced, making the data even more important.

Native to Asia, the spotted lanternfly has quickly spread since its initial detection in 2014. The insect is not a strong flier, yet its U.S. range is expanding, mostly due to the movement of vehicles, outdoor furniture, or other objects to which females glue their inconspicuous egg masses. Includes ID aids to help identify the spotted lanternfly in all its life stages, from egg mass through adult.

Most invasive insects are hidden away for the winter, but you still might encounter them when you split wood, move outdoor furniture indoors, or admire evergreen plants while on a hike.  Learn more about invasive pests you may come across and how to report them.

The Michigan Invasive Species Program’s new campaign  – “See it. Squish it. Report it.” – reminds Michiganders and visitors of the simple steps they can take to prevent new introductions of spotted lanternflies in the state. f 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.

Online Interface Encourages the Public to Assist in Surveying for and Reporting Spotted Lanternfly

The New York State Departments of Agriculture and Markets (AGM) and Environmental Conservation (DEC), and the Office of Parks, Recreation, and Historic Preservation (Parks) today announced an innovative effort to combat the spread of Spotted Lanternfly (SLF) in New York State. A new online interface will allow volunteer members of the public to assist in surveying for SLF and tracking associated data. The program encourages broader surveying for SLF and increased public awareness of this invasive pest, following confirmed finds of SLF in New York State this past fall.

The new initiative, which launched this week, invites volunteers to sign up to survey a specific area, or grid, of land on iMapInvasives. This online, GIS-based data management system is used to assist citizen scientists and natural resource professionals to protect against the threat of invasive species. Volunteers will also enter data from their survey work into iMapInvasives. More information about the program, including upcoming webinars, can be found at https://www.nyimapinvasives.org/slf.

The Spotted Lanternfly is detrimental to Delaware’s agricultural industries, the environment, and residential areas, and has an impact on interstate commerce.  In 2017, Delaware was the second state, other than Pennsylvania, to have found the insect. In Delaware, it was first detected in New Castle County, with recent findings in Kent County (October 2020).

Residents who live near Dover Air Force Base or in Sussex County are encouraged to report sightings of spotted lanternfly. Citizen reports help DDA inspectors determine how these insects move and which transportation pathways they utilize. These reports also allow DDA to notify agricultural operations with plants vulnerable to this insect.

In mid-2018, spotted lanternfly (SLF) nymphs and adults were found in northern Cecil County. If you see a suspect SLF insect, trap or photograph it and use the Report a Spotted Lanternfly Sighting in Maryland online form or contact the Maryland Department of Agriculture at DontBug.MD@maryland.gov.

The $900,000 grant will help Virginia Tech researchers see if the spotted lanternfly can help spread a fungus that kills the tree-of-heaven. The goal of the grant is to develop a native fungus as a biocontrol for the tree-of-heaven. Researchers are investigating whether the spotted lanternfly could help transmit the fungus from tree to tree, reducing the need for human intervention.

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.

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.

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.

The Spotted Lanternfly is an invasive species native to Asia. In 2014 it was found in Pennsylvania, and has since spread to multiple counties which are now quarantined. If you see a spotted lanternfly, it's imperative to immediately report it online or via phone by calling 1-888-4BADFLY. Especially if you are not inside the quarantine zone.

What else? Kill it! Squash it, smash it...just get rid of it. In the fall, these bugs will lay egg masses with 30-50 eggs each. These are called bad bugs for a reason, don't let them take over your county next. In March 2021, the Pennsylvania Department of Agriculture (PDA) added 8 additional counties to the Spotted Lanternfly Quarantine, for a total of 34 Pennsylvania counties now in quarantine.

The Illinois Department of Agriculture has confirmed the first detection of spotted lanternfly (Lycorma deliculata) in Illinois. Following a report of a live adult on Sept. 16, state, federal, and local officials coordinated a site visit near the area of the report and identified a moderately populated area of spotted lanternfly (SLF) on Sept. 18. Specimens were collected and submitted for identification, and confirmatory results were received on September 26. The spotted lanternfly does not present any human or animal health concerns.

If you see SLF or suspect it, report it to lanternfly@illinois.edu. A fact sheet, including photos, is available through the University of Illinois Extension [PDF, 1.95 MB].

The spotted lanternfly (SLF) is the newest invasive species that has found its way to the Bluegrass State.
