Red-bellied pacu is native to South America. Individual specimens have been caught since the 1960s, but no reproducing populations have yet become established in the U.S. This species was probably introduced through aquarium releases or fish farm escapes. The environmental impact is unknown.

Red-eared slider is native to the Mississippi River drainage. Throughout its nonindigenous range, this species is introduced primarily through pet releases and escapes since the 1930's. This species may compete with native turtle species, although despite its widespread occurrence little is known of the impact on indigenous ecosystems.

The spotted lanternfly is native to China. It was first detected in 2014 (but appeared to have been present in the U.S. for 2-3 years) and poses a serious economic threat to multiple U.S. industries, including viticulture, fruit trees, ornamentals and timber.

Spotted wing drosophila was first discovered in Hawaii in the 1980's and in the continental U.S. in 2008. It was possibly introduced in fruits imported from Asia. This insect is a pest of unripe berries and stone fruits capable of causing significant economic losses.

Sweet orange scab is native to South America. It was introduced to the U.S. in 2010, most likely through the movement of infected nursery stock. It's a fungus affecting the fruit of sweet orange and mandarin cultivars.

The tomato leaf miner was originally thought to be native to Central America, but now believed to have originated in Peru. This pest is not yet present in the United States. It may be transported through the fruit trade and it's impact caused yield losses of up to 100% in tomatoes.

The honey bee varroa mite was first detected in Asia and was introduced to the U.S. in 1987. It's means of introduction was via commercial transportation of infested bee colonies. The varroa mite is a serious worldwide pest of the European honeybee and is a major cause of colony collapses.

The Wisconsin Department of Agriculture, Trade and Consumer Protection (DATCP) caught 202,300 spongy moths (formerly named gypsy moth) in 10,044 traps this summer as part of the federal Slow the Spread of the Spongy Moth Program. "Wisconsin weather trends have allowed the spongy moth population to grow over the last several years," said Michael Falk, DATCP's trapping coordinator.

Spongy moth is an invasive pest that has been spreading westward since its introduction to North America. Caterpillars feed on the leaves of many species of trees and shrubs, especially oaks, and can cause severe leaf loss when feeding in large numbers. For more information, call (800) 642-MOTH (6684), email spongymoth@wisconsin.gov, or visit www.spongymoth.wi.gov.

Spotted lanternfly (Lycorma delicatula) was found in Indiana for the first time in Switzerland County earlier this week, the farthest west the insect has been found. A homeowner in Vevay contacted DNR’s Division of Entomology & Plant Pathology (DEPP) with a picture that was taken outside his home of a fourth instar, or developmental stage, larvae. DEPP staff surveyed the site and discovered an infestation in the woodlot adjacent to a few homes in the area. DEPP and USDA are conducting an investigation to determine exactly how large the infestation is and where it could have come from, as well as how to limit the spread and eradicate the population.

The Indiana DNR is asking for all citizens to keep an eye out for spotted lanternfly. The bright color of both the last instars and the adults of the insect should be present at this time of the year. Anyone that spots signs of the spotted lanternfly should contact DEPP by calling 866-NO EXOTIC (866-663-9684) or send an email to DEPP@dnr.IN.gov.

A population of the invasive Spotted Lanternfly (SLF) has been found in Mingo Junction, Ohio 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.

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.

Today, Michigan Department of Agriculture and Rural Development (MDARD) Director Gary McDowell confirmed the state’s first detection of spotted lanternfly (Lycorma delicatula) in Michigan. A small population of spotted lanternfly was detected in Pontiac in Oakland County last week with the United States Department of Agriculture (USDA) confirming the finding on August 10.

Spotted lanternfly moves easily on firewood, tires, campers, vehicles and more. Prevention and early detection are vital to limiting the spread of spotted lanternfly. If 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 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, first sighted in Pennsylvania, is an invasive pest to the U.S. See this photo essay to learn more about ARS's research efforts.

USDA scientists have discovered that the spotted lanternfly, an invasive threat to fruit crops and many trees, may have an Achilles heel – an attraction to vibration. A native of China, the insect was discovered in Pennsylvania in 2014 and has since spread to 13 other states. Though beautiful as an adult, the insect is a voracious eater that feeds on woody and ornamental trees as well as a wide variety of crops and plants. Left unchecked, Pennsylvania alone could lose hundreds of millions of dollars and thousands of jobs.

Richard Mankin, an entomologist with the USDA Agricultural Research Service’s Center for Medical, Agricultural, and Veterinary Entomology in Gainesville, FL, and colleagues found a new way to potentially corral and control the pests. Their research was published in the Journal of Economic Entomology.

The Rhode Island Department of Environmental Management (DEM) announces that the spotted lanternfly (SLF), an exotic pest that targets various plants and trees, has been detected for the first time in Rhode Island. Native to Asia, SLF is most commonly associated with "Tree of Heaven" (Ailanthus altissima) plants and also feeds on a wide variety of agricultural crops such as grape, apple and hops; and several native species of plants and trees including maple, walnut and willow.

A single SLF was found in an industrial/commercial area in Warwick near Jefferson Blvd, and a photo of the insect was sent to DEM through its online agricultural pest alert system. DEM's Division of Agriculture confirmed the sighting on August 2 and is asking the public to report any suspected sightings at the Spotted Lanternfly Sighting Report Form. No known population of SLF is currently present in this area. DEM will be conducting an extensive survey of the area based on US Department of Agriculture (USDA) recommendations to determine if there is any further presence of the invasive insect and will be providing outreach materials to businesses in the area.

Deceptively delicate and fragile in appearance, the Eurasian watermilfoil forms thick mats in shallow areas of a lake, quickly growing and spreading to block sunlight, killing off native aquatic plants that fish and other underwater species rely on for food and shelter. In North America, the plant threatens the diversity and abundance of native plants as well as the ecological balance of lakes and ponds, which in turn adversely affects recreational opportunities. If left unchecked, invasive watermilfoil will spread through a lake, or even to other lakes by transmission. An expert team of USDA Forest Service divers with invasive species and aquatics expertise is focused on rooting out the plant.

Feral swine (wild pigs, boars or feral hogs) are a destructive, invasive species that are prevalent in the U.S. and Canada. Federal, State, Provincial, local and territorial agencies are working together to manage the threat and damage caused by feral swine and to mitigate their impact. 

The American chestnut (Castanea dentata) was an iconic tree that is now functionally extinct. For a hundred years, researchers from multiple organizations have been working to restore this tree. A free online course – An Introduction to the American Chestnut – is now available. The course covers chestnut taxonomy, silvics, historical importance, ecology, and its demise. A second course in development will cover American chestnut restoration and management.

Love them or hate them, there's no doubt the European Starling is a wildly successful bird. A new study from the Cornell Lab of Ornithology examines this non-native species from the inside out. What exactly happened at the genetic level as the starling population exploded from just 80 birds released in New York City's Central Park in 1890, peaking at an estimated 200 million breeding adults spread all across North America? The study appears in the journal Molecular Ecology - "Environmental correlates of genetic variation in the invasive European starling in North America."
