Spotted Lanternfly Detected in Ohio

REYNOLDSBURG, OH (Oct. 27, 2020) – A population of the invasive Spotted Lanternfly (SLF) has been found in Mingo Junction just south of Steubenville, along the Ohio River. The initial report came from a resident who spotted a dead adult SLF on a commercial building on October 19, 2020. When Ohio Department of Agriculture (ODA) Plant Pest Control inspectors arrived, they were able to capture five live adult SLF in trees located nearby.

ODA has been working with the United States Department of Agriculture, Ohio Department of Natural Resources, Ohio State University Extension, and the Ohio Grape Industries Committee to do visual surveys, insect trapping, and outreach in the region.

SLF is a great concern to the grape and wine industry. The insect is fond of grapevines, fruit trees, hops, blueberry, oak, pine, poplar, and walnut. Adult SLF are attracted to the invasive Ailanthus tree, also known as tree-of-heaven, while nymphs feed on a wide range of hosts. Both adults and nymphs feed on stems and leaves, causing sap bleeding and reduced photosynthesis, which can eventually kill the plant.

Now through November is the best time to spot the SLF because it is in its most recognizable stages as a colorful winged adult plant hopper. After hatching in the late spring, the SLF goes through four nymph stages. By midsummer, the nymph SLF can be identified by its red body, roughly a half-inch in size, with black stripes and white dots. During the late summer until roughly November, the SLF is in the adult stage. These adults are larger, roughly one inch in size, with black bodies and brightly colored wings.

The public is the first line of defense against the SLF. If you believe you have seen an SLF in your area, you can easily report a suspected infestation by going to ODA’s Spotted Lanternfly Information Page and filling out a suspected infestation report. You may also call the Plant Pest Control Division at 614-728-6400.

Spot the Spot – Ohioans Encouraged to Look for the Spotted Lanternfly

We are urging Ohioans to be on the look-out for the spotted lanternfly (Lycorma delicatula) (SLF). This non-native insect was first discovered in Pennsylvania in 2014 and has been ‘popping-up’ in other states. We encourage others to become familiar with the insect and continue to be on the look-out for the actual insect itself, along with other signs and symptoms. Although not an outright killer of plants, it can be a stress factor causing plant decline, and sometimes death of certain host plants. This insect can also be a nuisance in numbers where recently reports in neighboring Pennsylvania have increased 500% from the previous year.

Below is a resource from Penn State Extension illustrating the life-cycle of the SLF. The insect overwinters in the egg stage where eggs are laid in masses on ‘any’ flat surface. If you were to spot SLF in Ohio, you would most likely be seeing adult activity this time of the year.

If you suspect seeing SLF in the buckeye-state, we encourage you to capture the insect(s) both literally and in photos, and report the suspect find in one of the following ways:

– The Great Lakes Early Detect Network (GLEDN) App that can be downloaded on your phone to report invasive species in Ohio and other Great Lake States. More information about the App can be found online at: You can also learn more by tuning in to some recorded presentations and videos shared by OSU colleagues. If you are monitoring the same site for SLF, you can also report negative finds to alert others that you are looking, but not finding SLF currently in that particular site.

– Suspect finds can also be reported on the Ohio Department of Agriculture’s website – Public Reporting Tab.

If you have an questions, reach out to ODA, your local OSU Extension office, or your Ohio Department of Natural Resources Division of Forestry Urban or Service Forester. Help join that battle of this invasive species by staying updated and resporting any suspect finds immediately. Thank you for your help in protecting Ohio.

Spotted Lanternfly Settling In a Little Too Close

COLUMBUS, Ohio — An invasive pest that was initially contained within Pennsylvania has spread to Delaware and Virginia, and insect experts worry the next stop will be Ohio.

Spotted lanternflies suck sap from fruit crops and trees, which can weaken them and contribute to their death. Native to China, the insect was first found in the United States in 2014 in Pennsylvania.

At this time, spotted lanternflies are still relatively far from the Ohio border. They have been found in the southeastern part of Pennsylvania, near Philadelphia. However, they can be spread long distances by people who move infested material or items containing egg masses.

“The natural spread would take a long time, but it would be very easy to be moved through firewood or trees that are being relocated,” said Amy Stone, an educator with Ohio State University Extension. OSU Extension is the outreach arm of the College of Food, Agricultural, and Environmental Sciences (CFAES) at The Ohio State University.

If it arrives in Ohio, the spotted lanternfly has the potential to do serious damage to the grape, apple, hops and logging industries, Stone said.

The lanternfly’s preferred meal is from the bark of Ailanthus or tree of heaven, which is typically not intentionally planted but instead grows on abandoned property and along rivers and highways.

Compared to the spotted wing drosophila or the brown marmorated stink bug, which seize on fruit and vegetable crops, the spotted lanternfly has a more limited palate so it likely would not do as much damage, said Celeste Welty an OSU Extension entomologist.

“Everybody’s fear is any new invasive pest will be like those two. But it seems to me, it’s not as much of a threat,” Welty said.

And unlike the spotted wing drosophila and the brown marmorated stink bug, the lanternfly is easy to spot because the adult bug is about 1 inch long and, with its wings extended, about 2 inches wide, Welty said.

For now, all that can be done to stem the spread of lanterflies is to stay watchful for their presence and any damage they may inflict. On trees, they zero in on the bark, particularly at the base of the tree. Lanternflies can cause a plant to ooze or weep and have a fermented odor. They can also cause sooty mold or a buildup of sticky fluid on plants as well as on the ground beneath infested plants.

An app developed by the CFAES School of Environment and Natural Resources allows users to report invasive species if they suspect that they have come across them. The app, which is called the Great Lakes Early Detection Network, features details about invasive species that people should be on the lookout for.

If someone sees a lanternfly, he or she should contact the Ohio Department of Agriculture at 614-728-6201.
