Spotted lanternfly is a major pest of concern across most of the United States. Spotted lanternfly (SLF) is an invasive planthopper native to China that was first detected in the United States in Pennsylvania in 2014. SLF feeds on over 70+ plant species including fruit, ornamental and woody trees with tree-of-heaven as its preferred host. Spotted lanternfly is a hitchhiker and can easily be moved long distances through human assisted movement.
Tree of heaven (TOH) is the preferred host for the spotted lanternfly (SLF). The ability to identify TOH will be critical to monitoring the spread of this invasive pest as the 4th-stage nymphs and adult spotted lantern-flies show a strong preference for TOH.

It is official. The Asian needle ant is our newest invasive insect pest and has now become a permanent resident, stinging ant. Two ant specimens taken from a wooded area in southern Indiana by an astute amateur entomologist, who observed their appearance and behavior as ‘out of the ordinary’, was submitted to the Indiana Department of Natural Resources and to the Purdue University Plant and Pest Diagnostic Laboratory for species identification in February, 2022. Both were confirmed to be Formicidae: Brachyponera chinensis, commonly known as the Asian needle ant, not previously recorded from Indiana.
Asian needle ants (ANAs), originally from Eastern Asia (China, Japan, and Korea), were first discovered in the United States in the early 1930s, but only recognized as a pest since 2006. They have been officially established in several states in the U.S. including North Carolina, South Carolina, Alabama and Georgia and, have been anecdotally reported as far north and west as New York, Tennessee and Kentucky.
Note that stings to humans will be moderately painful (potentially causing severe allergic reactions to susceptible individuals) much like fire ant or bee stings, but fortunately because these ants are much less aggressive in protecting their nests, the number of stings per encounter will be less.
The First Report of the Invasive Asian Needle Ant in Indiana pdf provides more details on their identification and biology.
If you want to confirm a sighting of the Asian needle ant please contact the Purdue University Plant and Pest Diagnostic Laboratory at this time. More information will be presented as experts monitor the spread.

Wild Bulletin, Indiana Department of Natural Resources: As you prepare your boat or recreational equipment to get back on the water this spring, remember to look for aquatic hitchhikers. Zebra mussels, aquatic plants like Eurasian watermilfoil or starry stonewort, and many other invasive species continue to be a threat to Indiana’s waters by degrading fish habitat and negatively affecting recreational boating and fishing. The most common locations where plants, mussels, and animals hitch a ride include:
Boat owners are asked to drain water from bait buckets, live wells, and boats before leaving the boat landing; leave drain plugs out while travelling on land; clean and dry anything that came in contact with water; and dispose of unwanted bait in the trash. Learn more about aquatic invasive species and how to prevent their movement.
Learn how to stop aquatic hitchhikers.

Purdue Forestry and Natural Resources’ extension efforts over the past two years amidst the COVID-19 pandemic were recognized in the Purdue Extension Specialist Quarterly newsletter (pdf).
The transition to virtual content brought expertise across subject matter areas, ranging from forestry and wildlife, to aquatic sciences and entomology, to the masses in the form of several video series which collectively earned nearly 150,000 views.
The FNR Extension team included: Jay Beugly, Jarred Brooke, Nick Burgmeier, Barny Dunning, Diana Evans, Lenny Farlee, Jason Hoverman, Liz Jackson, Brian MacGowan, Patrick McGovern, Wendy Mayer, Charlotte Owings, Lindsey Purcell, Bee Redfield, Shelby Royal, Bob Rode, Kara Salazar, Mike Saunders, Amy Shambach, Rod Williams, Mitch Zischke, as well as frequent Entomology contributors: Elizabeth Barnes, Cliff Sadof.
The feature in the fourth quarter newsletter begins:
“While Covid caused limitations on travel and in-person events nationwide, across Indiana, many were spending more time in outdoor recreational activities, hiking, bird-watching, hunting and fishing, or managing natural resources properties. Adjusting to the pandemic, the FNR team created an innovative and team-oriented instruction approach through skill-building in video production with coordinated connection and crosspromotion of resources.
“Forestry and Natural Resources (FNR) faculty, specialists, staff, and students, with invited partners across research and Extension, delivered 45-minute Ask an Expert Facebook Live programs for 35 weeks. Programs covered many FNR specialties: Animals & Insects (bats, bird, cicadas, coyotes, deer, fish, frogs, hellbenders, moles, pollinators, salamanders, snakes, toads, turtles, and wood pests); Plants & Ecosystems (invasive plant species, hardwood ecosystems, native grasses for wildlife, conservation tree planting, rainscaping, fall food plots, and selecting, planting and inspecting trees); and Management & Operations (prescribed fires, aquatic plant and pond management, and fish and wildlife management).

Governor Eric Holcomb has proclaimed February 27th to March 5th as Invasive Species Awareness Week in Indiana.
This serves as an important reminder for Hoosiers to be aware and report potentially devastating invasives.
This proclamation states “invasive aquatic, riparian and terrestrial species influence the productivity, value and management of land and water resources in Indiana and the costs to prevent, monitor and control invasive species costs Indiana millions annually and after habitat destruction, invasive species are a great threat to biodiversity and threaten the survival of native plants and animals and interfere with ecosystem functions by changing processes like fire, nutrient flow and flooding”.
It continues with “invasive species impede industry, threaten agriculture, endanger human health and are becoming increasingly harder to control as a result of rapid global commercialization and human travel; and invasive species are as significant threat to almost half of the native species currently listed as federally endangered.”
As Invasive Species Awareness Week starts Sunday, February 27th, the Indiana Department of Natural Resources (IN DNR), Purdue Extension-Forestry and Natural Resources and the Indiana Invasive Species Council will answer any questions you may have.

Led by Kyle Daniel, nursery and landscape outreach specialist in the Department of Horticulture and Landscape Architecture, the Purdue Landscape Report is a collaborative effort between Purdue Extension specialists and diagnosticians in the departments of Botany and Plant Pathology, Entomology, Forestry and Natural Resources, and Horticulture and Landscape Architecture. Articles cover everything from urban forestry and tree maintenance to pest and disease problems and management to plant selection and turf science. In addition to an email newsletter and online blog, PLR staff also provide live interactive webinars in order to highlight content and respond to questions from the audience.
In response to the pandemic, the Purdue Landscape Report staff also began a live, to addresses articles and hot topics. That series garnered more than 2,000 views.
In a January 2021 survey sent to PLR subscribers, 88% of respondents said they believed that the newsletter improved their ability to diagnose a problem, while 76% said that PLR has had a positive economic impact on their business.
A local professional shared that “Sometimes when I open up the PLR, it is like you have been reading my mind. The problem I have been seeing or thinking about is there in your headlines.”
One PLR subscriber said “The Purdue Landscape Report is a great resource for myself and my team members. Within each issue is one or more topics that our team has encountered or discussed recently and the information provided by a very reputable source gives us the material needed to provide the best service to our clients and increase our knowledge base. The virtual sessions are another great resource provided that give an opportunity to have specific questions answered by experts.”
The impact extends from landowners to industry professionals and beyond.
“Often we take for granted the information produced in the PLR and we forget the countless dollars we have saved from information in the PLR,” said Rick Haggard, Indiana Nursery and Landscape Association Executive Director.
“The Purdue Landscape Report provides timely information to the Indiana Arborist Association members and associated parties in a format that is easily accessed and understood,” Associate Executive Director of IAA Ashley Mulis said. “The collaboration that goes into providing this product demonstrates the cohesive nature of several departments within Purdue University and the open sharing and comparison of information. The Purdue Landscape Report is an excellent addition to the many publications offered within Purdue Extension in helping resource professionals manage the ever-changing landscape of pests, diseases and best management practices.”

Purdue Landscape Report: Spotted lanternfly (SLF) (Lycorma delicatula), a serious invasive plant pest, has been reported to be in Indiana. This federally regulated invasive species harms plants by slowing their growth and reducing fruit production, especially in vineyards and orchards. Finding this pest this far west of its previously known distribution makes it possible for SLF to be anywhere in Indiana. Knowing where this pest is located can help us respond more effectively to this pest.
Right now, the Indiana DNR is asking for all citizens to keep an eye out for spotted lanternfly. The bright color of late stage immatures and adults are easily recognized at this time of the year. Anyone who spots signs of the spotted lanternfly should contact the Indiana Division of Entomology and Plant Pathology (DEPP) by calling 866-NO EXOTIC (866-663-9684) or send an email (with a photo of the insect if possible) to DEPP@dnr.IN.gov. For more information about this or other invasive pests see the following link.

What is Spotted Lanternfly?
Spotted lanternfly is a planthopper that originated in Asia. It was first discovered in the United States in Pennsylvania in 2014. The Pennsylvania Department of Agriculture was unable to limit the spread of this pest because it is an effective hitchhiker and is often spread unknowingly by humans.
Adult spotted lanternfly has two sets of wings, and the underwing has a very distinct red color with spots on the outer wings. The fourth instar of the insect is bright red with black and white markings. The egg masses of this invasive insect look like mud and they can be spread by vehicle transport including recreational vehicles, cargo carriers (truck transport) and freight trains. They can also be spread through trade materials sold in infested areas that are shipped out of state including nursery stock, outdoor furniture, lumber, etc. Anyone receiving goods from the east coast should inspect for signs of the insect, especially if the commodity is to be kept outdoors.
