The Maine Department of Agricultural, Conservation and Forestry (DACF) announced finding egg masses of the invasive spotted lanternfly (SLF) on trees in Maine communities and is urging residents to report any sign of the invasive pest. The egg masses were found on trees from Pennsylvania, where SLF is established and planted in Boothbay, Freeport, Northeast Harbor, and Yarmouth. DACF urges anyone who received goods or materials, such as plants, landscaping materials, or outdoor furniture, from a state with a known SLF infestation to carefully check the materials, including any packaging, for signs of SLF. If any life stages of SLF are found, residents should take a photo or collect the specimen and report any pest potential sightings to bugwatch@maine.gov. Residents should look for large, gray insects, about one inch long, with black spots and red underwings, or inch-long, rectangular yellowish-brown egg masses covered with a gray waxy coating.

Because no live SLF has been found in Maine, there is currently no evidence that SLF has become established. The DACF Horticulture Program has inspected all the suspect trees and asks the homeowners and landscape companies to keep an eye on the areas where egg masses were found to confirm that no live populations are present. Spotted lanternfly has not previously been found in Maine.

The West Virginia Department of Agriculture (WVDA) has confirmed a second population of the invasive Spotted Lanternfly (Lycorma delicatula) near Ridgeley, WV. The invasive pest was reported through the WVDA’s Bug Busters hotline on September 28 and confirmed by WVDA and APHIS employees the following week. "Our staff have been diligent on public outreach and inspections. The fact this report came from a resident, shows folks are on the lookout for this new, invasive pest," said Commissioner of Agriculture Kent Leonhardt. "If you believe you spot the Spotted Lanternfly, make sure to report it to the WVDA." For more information or to report potential Spotted Lanternfly sightings, contact bugbusters@wvda.us or 304-558-2212.

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.

The Tennessee Department of Agriculture, United States Department of Agriculture – Animal and Plant Health Inspection Services, Tennessee Department of Health, and University of Tennessee Institute of Agriculture (UTIA) has announced the detection of the invasive Asian longhorned tick in Tennessee. The Asian longhorned tick has now spread to 11 states. The Centers for Disease Control and Prevention reports that there is no evidence that the tick has transmitted pathogens to humans or animals in the U.S. Two Asian longhorned ticks were recently found on a dog in Union County, and five were found on a cow in Roane County. In the U.S., the tick has been reported on 17 different mammal species.

On August 5, the Washington Department of Fish and Wildlife (WDFW) received notification from a local wholesale aquarium company in Renton of possible invasive freshwater mussels on a shipment of Marimo moss balls (Aegagropila linnaei). Moss balls are a commonly used decorative algae in aquariums and water gardens. Lab testing confirmed the mussels were zebra mussels (Dreisena polymorpha), a prohibited aquatic invasive species in Washington that, if established in local waters, would be capable of causing significant infrastructure and environmental damage. Zebra mussels and a close relative, the quagga mussel, are not known to be established in Washington.

The North Carolina Wildlife Resources Commission (NCWRC) announced today that zebra mussels, a harmful invasive aquatic species, have been identified in an Iredell County waterbody. This is the first time this species has been identified in the wild in North Carolina. On Thursday, September 21, 2023, NCWRC, with assistance from scuba divers from the U.S. Fish and Wildlife Service, investigated and confirmed a report of zebra mussels in a quarry on private property. NCWRC believes the mussels are contained to the quarry and is working on options for treatment while continuing its investigation.

To report suspected zebra mussels, please contact the NCWRC's district fisheries biologist offices. Visit NCWRC's aquatic nuisance species webpage for guidance on disinfecting snorkel and SCUBA gear and for more information on zebra mussels.

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.
