![]() When at rest, the forewings lay tent-like over the body. The hind wings are red with patches of black and white. The front wings are a translucent gray with black spots, transitioning to a black tiled pattern at the tips. Adults measure approximately 1 inch long and ½ inch wide at rest, and 1½ to 2 inches wide with wings spread. Spotted lanternfly is a large, sap-feeding planthopper that feeds from the phloem tissue of host plants. These insects have four wings and a piercing-sucking mouthpart that is used to pierce their food source and suck out nutritive fluids. Spotted lanternfly is not a fly, but a type of planthopper (order Hemiptera, family Fulgoridae). Spotted lanternfly nymphs and adults have been reported feeding on wild and domestic grapes, hops, fruit trees, willow, various hardwood trees, pines, shrubs, and vines. 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. The preferred host of SLF is Tree of Heaven (Ailanthus altissima) another introduced invasive species. Residents can also report suspected finds via the Great Lakes Early Detection Network (GLEDN) mobile app. Residents are asked to be vigilant and report any suspected finds by calling a local Ohio State University Extension office or by using the Ohio Department of Agriculture website. For an updated map of confirmed populations, visit the Ohio Department of Agriculture website at /divisions/plant-health/invasive-pests/slf. It has since been sited and reported in other counties. The Ohio Department of Agriculture issued a quarantine for SLF in Ohio on Octo(ODA 2021). Spotted lanternfly was first detected in Ohio in October 2021 in Jefferson County. For more information on its spread, please see the references at the end of this fact sheet.Īs with any new invasive species, early prevention and detection are crucial to manage spread and impact of these non-native pests. Though quarantined by the United States Department of Agriculture (USDA) Animal Plant Health Inspection Service (APHIS) and the Pennsylvania Department of Agriculture, the insect spread to additional counties within Pennsylvania and to Virginia, Delaware, Maryland, Massachusetts, New York, New Jersey, and West Virginia. Spotted lanternfly has the potential to cause harm to the tree fruit, grape, and hops industries. In the United States, it was discovered in 2014 in southeastern Pennsylvania, Berks County. However, it has been reported as a serious non-native, invasive pest in Korea. Spotted lanternfly is thought to be native to China, Japan, Vietnam, and Taiwan. Management of SLF is focused on preventing their spread on vehicles or other objects through quarantines, trapping of nymphs, removal of host plants, and chemical control.The spotted lanternfly (SLF) ( Lycorma delicatula) is a new non-native invasive insect pest to the United States. Egg masses laid by females are light gray and covered by a mud-like substance and can be deposited on nearly any relatively flat surface such as tree trunks, buildings, fences, rocks, vehicles, or train cars. SLF nymphs and adults may also congregate in swarms in yards and farms, making them a nuisance pest. ![]() The honeydew is also colonized by a fungus called “sooty mold” which can ruin grape and hops harvests, decrease photosynthesis, and is generally unsightly. In addition to feeding damage, SLF nymphs and adults produce copious amounts of sticky, sugary liquid known as “honeydew” which can be attractive to ants, flies, and wasps. Favored hosts include the non-native invasive tree-of-heaven, grapes, and hops. SLF feed on a wide variety of woody and herbaceous plants, causing wilting and dieback and stress that can make host plants more susceptible to damage by other biotic or abiotic factors. Additional infestations, or individual SLF or egg masses, have since been documented in several other states. It was first discovered in North America in southeastern Pennsylvania in 2014.
