Invasive Species Alert: Spotted Lanternfly The Spotted Lanternfly (SLF), Lycorma delicatula, is an invasive insect species native to Asia. It was ﬁrst discovered in the United States in Berks County, Pennsylvania in 2014 and has since spread to New Jersey, Delaware, Maryland, Virginia, West Virginia, New York, Connecticut and Ohio. Cranbury residents should be aware that SLF has been sighted in our township. This insect has the potential to greatly impact agricultural crops and hardwood trees. SLF feeds on sap from over 70 different plants, including grapevines, maples, black walnut, and other important species in New Jersey. It has a strong preference for economically important plants and the feeding damage signiﬁcantly stresses the plants which can lead to decreased health and potentially death. What You Can Do Get Informed: To learn more about SLF and what you can do to prevent its further spread, please visit the NJ Department of Agriculture Spotted Lanternfly Program website: https://www.nj.gov/agriculture/divisions/pi/prog/pests-diseases/spotted- lanternfly/about/. Report Sightings: The NJ Department of Agriculture is asking homeowners to report spotted lanternfly sightings through their online reporting tool: https://www.nj.gov/agriculture/divisions/pi/prog/pests- diseases/spotted-lanternfly/#reporting-tool. Remove Host Trees: Spotted lanternfly strongly prefers the ailanthus tree, also known as “Tree of Heaven.” This plant is also considered an invasive species, and is easily mistaken for staghorn sumac, a native that grows in similar soils and areas. For help identifying the SLF host tree, homeowners are encouraged to contact the Cranbury Shade Tree Commission ([email protected], 609-664-3130). CSTC, 04/20/21 .

Spotted Lanternfly Facts
Norristown Farm Park Spotted Lanternfly Research Frequently Asked Questions What is the spotted lanternfly and why should we be concerned about it? The spotted lanternfly (SLF) is an invasive insect from Asia that first was found in North America in Berks County, Pennsylvania, in 2014. The pest since has spread to at least 26 Pennsylvania counties, as well as to New Jersey, Delaware, Maryland, West Virginia and Virginia. At risk are agricultural commodities — including grapes, tree fruit, nursery plants and hardwood lumber — as well as natural habitats, parks and backyards. Economists warn that this insect, if not contained, could drain Pennsylvania’s economy of at least $324 million annually and cause the loss of about 2,800 jobs. What is being done to stop the pest? To sustainably manage spotted lanternfly populations and slow the pest from spreading, Penn State's College of Agricultural Sciences and Penn State Extension is researching the insect’s biology and behavior, evaluating management tactics, and educating growers and other businesses, local officials and the public on this pest. Meanwhile, our partners, the Pennsylvania Department of Agriculture (PDA) and the U.S. Department of Agriculture (USDA) are also working to manage populations in high-risk areas to limit further spread. Several methods are being used to help manage the pest, including destruction of egg masses, placement of tree traps, and removal of preferred hosts, including the invasive plant, tree of heaven (Ailanthus altissima). Spotted lanternfly also is currently managed using broad-spectrum insecticides applied to individual trees. While this method can successfully kill spotted lanternflies, this is labor intensive, can have other environmental impacts, and is not cost-effective to manage the SLF population across large areas.

Spotted Lanternfly Questions
Spotted Lanternfly Frequently Asked Questions What is a Spotted Lanternfly/Where did they come from? --The Spotted Lanternfly (SLF) is an invasive insect new to the United States. Spotted Lanternflies are native to Southeast Asia, but they have been introduced to other areas of Asia as well—including to Korea, where Spotted Lanternflies are a major pest to agriculture. Spotted Lanternflies are reproducing quickly in our area of south-eastern Pennsylvania, and Spotted Lanternflies have the potential to become a major threat to Pennsylvania’s agriculture and forestry industries. --For more information, please click here: http://www.agriculture.pa.gov/Protect/PlantIndustry/spotted_lanternfly/Pages/default.aspx How do I identify a Spotted Lanternfly if I see one? --Spotted Lanternflies go through five (5) stages of growth after hatching from eggs. These stages, called nymphs (or ‘instars’ in scientific literature), are quite different. The young nymphs are black with bright white spots. The next stages of growth are similar, but the nymphs become larger. The 4th stage of Spotted Lanternflies, prior to adulthood, is vibrantly red with distinct patches of black and equally distinct bright white spots. The adult Spotted Lanternfly is a winged, flying leaf-hopper about 1 to 1 and ¼ inch long. During this, the final stage of Spotted Lanternfly development, the insect has grey wings with dark black spots. When the Spotted Lanternfly opens its wings, one sees a bright red underwing with black wingtips. --Spotted Lanternflies live through the winter only as eggs. These eggs form egg-masses laid on trees, under bark, on rusty metal, on plastic yard objects, on cars and trailers, on outdoor grills, and on many other surfaces.

Spotted Lanternfly Identification and Control
Spotted Lanternfly Identification and Control Paul J Kurtz Entomologist New Jersey Department of Agriculture Distribution • The Spotted Lanternfly (SLF) is a planthopper from Asia, specifically found in China, India, Vietnam • First found in Berks County, Pennsylvania during the Fall 2014, at a stone importer prompting the immediate quarantine of Pike and District townships. • The initial introduction is believed to have been in 2012. • As of 2020 there are 8 counties under quarantine in NJPA for SLF. • Currently in 6 states and detected in another 3. Distribution: US Centered Map The USA is at the same latitudinal area as China and Japan, meaning same general climates and habitat patterns. Lifecycle Egg Laying: Adults: July 24-December September - November Eggs: Late September-June One Generation Per Year Fourth Instar: Hatch and 1st Instar: July - September Late April- June Third Instar: June - Mid-July Second Instar: May - June Adults . Approx. 1 inch in length. The forewing is gray with black spots of varying sizes and the wing tips have black spots outlined in gray. Hind wings have contrasting patches of red and black with a white band. The legs and head are black, and the abdomen is yellow with black bands. Adults . While a poor flyer, the Spotted Lanternfly is a strong jumper. Adults can be seen as early as July. In the fall, adults switch hosts to focus on Tree of Heaven (Ailanthus altissima). Egg laying begins in September and continues up through the onset of winter, until a hard killing frost. Adults often cluster in groups to feed, mate and lay eggs.

Spotted Lanternfly Alert in Monroe County by Rep
Spotted Lanternfly Alert in Monroe County By Rep. Rosemary M. Brown (R-Monroe/Pike) The Spotted Lanternfly is an invasive insect, native to China, India, Vietnam and Korea, that has been discovered in parts of eastern Pennsylvania. They are different from other invasive insects we have encountered in our state, both in terms of physiology and behavior, and its habits have changed since it was discovered in Berks County in September 2014. This insect is a serious threat to $18 billion worth of agricultural commodities in our state, including our apples, grapes and hardwoods. Our interstate and international export industry faces a serious risk on the world market, as trade barriers that prevent shipments from our state would lead to the potential loss of certain industries. Community members in the following 13 counties have been asked to take personal responsibility by participating in initiatives to control and eradicate the Spotted Lanternfly: Berks, Bucks, Carbon, Chester, Delaware, Lancaster, Lebanon, Lehigh, Monroe, Montgomery, Northampton, Philadelphia and Schuylkill. This is part of a strategic effort to contain the insect’s spread, and though the insect hasn’t been confirmed in each of these counties, there is a high risk of its rapid spread throughout the region. The Spotted Lanternfly adult is approximately one inch long and a half an inch wide, with forewings that are gray with black spots and the wing tips. After hatching and before reaching adulthood, this insect progresses through three life phases, known as instars. Both males and females mate numerous times, with females laying 30-50 eggs in each egg mass.

Identification and Biology of Spotted Lanternfly Lycorma( Delicatula)
Identification and Biology of Spotted Lanternfly Lycorma( delicatula) The spotted lanternfly (Lycorma delicatula) is an invasive insect pest of fruit, ornamental, and woody trees. Spotted lanternfly is native to China, Bangladesh and Vietnam, but was first discovered in southeastern Pennsylvania in late 2014. Since this initial discovery, it has spread to at least eight additional states. The spotted lanternfly damages trees by feeding on them, and its waste product, honeydew, encourages the growth of mold that harms the health of the host plant. Tree-of-heaven (Ailanthus altissima) is a preferred host, but this pest could potentially devastate grape (Vitis spp.) and logging industries. Identification The spotted lanternfly is a planthopper, with the adult being approximately 1 inch long and 0.5 inch wide at rest (Fig. 1). Its forewings are gray in color with distinctive black spots and outlined wing tips, while the hind wings are red and black in color and contain a white band. Wings are held closed over the Fig. 1. The adult spotted lanternfly, shown resting on tree-of-heaven (top) and with its wings spread out (bottom). Photos: Lawrence Barringer, body unless in flight. Its abdomen is mostly black, Pennsylvania Department of Agriculture, Bugwood.org with yellow bands between segments. The early (1st – 3rd instar) immature stages are covered with white spots on a black body (Fig 2), and then develop red patches as they mature (4th instar) (Fig. 3). Are they found in Illinois? No. As of this writing, spotted lanternfly populations have only been found in the Mid- Atlantic region of the U.S., but they are capable of spreading quickly.

Be Alert for Spotted Lanternfly
Be Alert for Spotted Lanternfly Be Alert for Spotted Lanternfly Jamie Dahl, Forest Outreach Coordinator, Central State University Extension Ashley Kulhanek, Educator, Agriculture and Natural Resources, Medina County The spotted lanternfly (SLF) (Lycorma delicatula) is a new non-native invasive insect pest to the United States. Spotted lanternfly is thought to be native to China, Japan, Vietnam and Taiwan. However, it has been reported as a serious non-native, invasive pest in Korea. In the United States, it was discovered in 2014 in southeastern Pennsylvania, Berks County. Spotted lanternfly has the potential to cause harm to the tree fruit, grape, and hops industries. Though quarantined by the United States Department of Agriculture (USDA) Animal Plant Health Inspection Service (APHIS) and the Pennsylvania Department of Agriculture, as of March 2020 the insect has spread to additional counties within Pennsylvania and to Virginia, Delaware, Maryland, Massachusetts, New York, New Jersey, and West Virginia. For more information on its spread, please see the references at the end of this factsheet. As with any new invasive species, early prevention and detection are crucial to manage spread and impact of these non-native pests. As of March 2020, SLF has not been confirmed in Ohio. Nonetheless, residents are asked to be vigilant and report any suspected finds to the Ohio Department of Agriculture, to a local Extension office, or via the Great Lakes Early Detection Network (GLEDN) mobile app. Host Range The preferred host of SLF is Tree of Heaven (Ailanthus altissima) another introduced invasive species. SLF, however, feeds on a wide variety of plants throughout its life cycle, with nymphs reported as having a more diverse palate than their adult counterparts.
