Purdue Landscape Report: When talking about invasive species, specialists are most commonly talking about some kind of plant or insect that is making an impact on landscape plants, soil, or hardwood. Most of these species are relatively easy to understand, with a biology that typically resembles that of a native counterpart. Wood-boring insects, vining plants, and fast-growing shrubs all have similar native species that landowners deal with on a regular basis. And then, some invasive species are just plain weird, like the invasive hammerhead worm!

Hammerhead worms, sometimes called shovel-headed garden worms, are a type of land planarian, or flatworm. Flatworms are worm-like organisms that lack the segmentation of earthworms and have the ability to regenerate from parts and pieces. Hammerhead worms belong to a subset of planarians, the genus Bipalium; while there are a few native species of Bipalium, most are from tropical regions. It is believed that hammerhead worms have been present in North America for long time, preferring environments that stay warm and moist through most of the year. Hammerhead worms are named for their spade-shaped head and typically have bright colors with dark lines running the length of their bodies. They are often found in indoor spaces and greenhouses that are temperature controlled and maintain humid conditions. Hammerhead worms can also be found living under rocks, fallen trees, or anywhere that can maintain a high enough relative humidity. While some flatworms are able to live in drier conditions, Bipalium need moisture in order to survive.

Members of Bipalium are predatory, consuming invertebrates like earthworms, snails, slugs, and some soft-bodied insects. Once they capture a prey item, they envelop it in a mouth-like organ located on the underside of their bodies. The primary issue with hammerhead worms is the potential damage they can do by preying on beneficial organisms that maintain soil and plant health. Hammerhead worms, and all other planarians, lack a closed body plan that uses a one-way digest system. Once they eat something, it is digested and waste is excreted through that same mouth-like opening. Some members of Bipalium can also use a toxin called tetrodotoxin to subdue their prey; however, they only produce a small amount and lack a way to use it on a larger organism. While they are often confused for more dangerous species, the Bipalium in North America do not represent a human health concern. Just keep any pets or children away from them, and if found, and use gloves if you’re forced to handle them.

As mentioned above, one of the more unique traits of Bipalium, and planarians in general, is their capacity to regenerate new individuals from parts and pieces. A piece as small as 1/279th of the whole can regenerate into a new individual. Do not attempt to chop up or crush hammerhead worms, or you may be dealing with several dozen when new worms develop in two weeks. However, even though it seems like hammerhead worms could reproduce very quickly, it’s still fairly uncommon to see one. If found, place it in a bag or bucket with either salt, alcohol, or vinegar until the worm is dead. As long as you do not cut or chop up the worms, it is very unlikely you’ll have to deal with more than one at any given time. Just keep your eyes open and remember to report any sightings to 1-866-NOEXOTICS!

Purdue Landscape Report: Spotted lanternfly (SLF) has been the subject of a lot of media attention in the last few years.  In the east, states like Pennsylvania and New York have been dealing with heavy infestations since the insect was first detected in 2014.  In Indiana, this invasive planthopper arrived three years ago, infesting two counties on the eastern side of the state.  Since then, the Indiana Department of Natural Resources and Purdue University have been working together to mitigate the spread of this insect as well as educate Hoosiers on what they can do to help.  Spotted lanternfly is still on the move, and this update will help refresh you on how this bug works, and where they are headed.

Life cycle
Spotted lanternfly is an annual insect, having only a single generation in a year under normal conditions.  The insect goes through incomplete metamorphosis; immature stages, called nymphs, resemble smaller, wingless versions of the adults.  Nymphs will begin to appear in April or May, developing through four instars, until they reach adulthood in late summer.  With each instar, the period in between molting, the nymph will grow larger, develop wingpads, and eventually change color.  Early instars are black with a white dot pattern, while later instars will be bright red with black and white patterning (Fig. 1).  Late instar nymphs are often compared to milkweed bugs or lady beetles.  Once they complete development in the late summer or early fall, they will mate and lay egg masses covered in a protective substance that makes them resemble mud.  Eggs masses will overwinter until the spring, while adult insects will die as temperatures cool.  In Indiana, depending on temperature, adults can be seen as late as early November.

Impact
Spotted lanternfly is a sap-feeding insect, using syringe-like mouthparts to drain nutrients directly from plant tissues.  Like other sap-feeding insects, the activity of SLF wounds the plant, creating openings for various pathogens to exploit.  Feeding by SLF has been shown to reduce overall health of their hosts, reducing their capacity to survive overwintering, and potentially kill the host plant depending on species.  They also produce a sugary waste known as honeydew; while honeydew itself is not harmful, it acts as a growing substrate for sooty mold, which can have a serious impact the photosynthesis of understory foliage as well as attract other nuisance insects.

Spotted lanternfly is a generalist herbivore and can feed on over 100 different species of plant and tree in Indiana.  However, this insect has shown strong preference towards certain species, often with devastating consequences.  The most preferred host is tree-of-heaven, an invasive tree species in North America.  Tree-of-heaven is the primary host of SLF in their shared native range, and the insect appears to experience high reproductive success on it even when they share a new environment.  Grapes are also highly preferred by SLF, and infestations will typically result in overfeeding and the death of the plant.  Black Walnut, American river birch, and various maple species are also at risk of severe damage from this insect.   Evidence has also suggested that maple, when used for syrup production, will experience reductions in yield and quality when attack by spotted lanternfly.

Where are they now?
Spotted lanternfly has been present in Indiana since 2021, first arriving in Huntington and Switzerland Counties.  In Huntington, the infestation occupies a stand of tree-of-heaven next to an industrial parking lot.  Tree-of-heaven moved into the neighboring residential area, allowing SLF to also spread with it. The more rural infestation in Switzerland County was traced to a vehicle transported from Pennsylvania, and the insect has taken advantage of patches of tree-of-heaven in nearby wooded areas.  While both infestations have strongly associated with the insect’s primary host, there is some evidence that SLF is beginning to take advantage of other nearby plants, such as maple.  In the last year, SLF moved a significant distance and has been detected in several more counties, including Elkhart, St. Joseph, Porter, Allen, Dekalb, and Noble Counties.  Most of the activity has been found on tree-of-heaven along rail lines, supporting the idea that the insect is dispersed by rail traffic moving westward out of infested areas.

It’s important to remember that trains aren’t the only vehicles that can have SLF passengers.  These insects, and their egg masses, can be found on just about any surface, including the car you drive to work, the RV you used for recreation, semi-trucks that cross the country, and more.  Purdue Entomology and Indiana DNR are encouraging everyone to inspect their vehicles when traveling through any of the infested areas.  Also check all recreational vehicles and trailers for spotted lanternfly egg masses; if found, scrape them off into a bag or bucket filled with soapy water.  This fall and winter, we also want to encourage everyone to please burn any firewood where you buy it, and please don’t move it off your property if you chop it yourself- especially if you are burning tree of heaven.  Egg masses will stick to firewood and can survive our winters very well.

What can I do?
We are still learning about the spotted lanternfly’s distribution through Indiana, and we need the help of citizen scientists to effectively track the insect’s movement.  If you believe you’ve seen spotted lanternfly, please report it using any of the resources listed below.  You can also feel free to reach out to Bob Bruner, Exotic Forest Pest Educator, by emailing them at rfbruner@purdue.edu, or you can report sightings by calling 1-866-NOEXOTIC.

One of the best parts of spring is seeing all of the wildlife seemingly come to life around us. Unfortunately, that activity can also bring new challenges to homeowners. One of the most common and widespread problems is lawn damage caused by moles.

In Indiana, eastern moles cause significant lawn damage. Characteristic signs of damage are the raised surface tunnels (these make your lawn uneven and feel “spongy” when you walk across it) and the dirt mounds created when moles dig deeper tunnels. A single mole can dig many feet of tunnels; one study found a single mole constructed 31 m of surface tunnels in a day.

Biologists actually know very little about moles compared to many species. It is assumed they are territorial and solitary (except during the breeding season), but that has yet to be determined. The only home range study of eastern moles was published in 1976. That study found that the average home range size of male moles was just over 2.5 acres; females had an average home range size of two-thirds of an acre. In reality, there is likely much variation across habitat types and season. Clearly, small yards in urban areas are capable of sustaining many moles.

One of the most effective ways to control moles in the yard is by trapping. It just so happens that the best time to trap them is right now. In May, moles are actively looking for food (mostly earthworms and insects) in the top layer of the soil profile; however, they have not yet had their litter of up to four young. Thus, a little trapping effort now can save you more effort, and less damage, later.

There are a lot of different kinds of mole traps on the market. Which do you choose? Regardless of the type of trap, it should be in good working order. Poorly kept traps that are rusty with loose or broken parts are not worth setting out. In terms of the specific type of trap that you use, it’s really up to you. With types of traps, I use the analogy of computer programs. There are advantages and limitations to most computer programs, but they all get the job done they were intended to do. Different people seem to find different programs easier to work with than others. Perhaps most often, we simply use the first program we learned to use, and as long as it works, there’s not much point in learning another. I think the same is true of traps. We tend to have success with the ones that we first learned or have some experience with using.

The main point is to start trapping now – don’t wait for the damage to get worse. Select relatively straight surface tunnels for trap locations. If you only have one trap at your disposal, you may want to also mark a couple other potential trapping locations. Collapse these locations by stepping on them and marking them with a pin flag. If you aren’t having success catching a mole in your initial location, you can try moving to one of these if the tunnels are repaired. It may be that you initially chose a tunnel that was not a primary tunnel. However, it also may mean that your trap was not set properly.

Finally, you may come across some references that will direct you to check the traps frequently. While this is absolutely critical for live traps, it is not for mole traps since they are kill traps. There is no requirement to check them regularly other than to see if you have a mole. However, a trap with a dead mole won’t catch anything else. This is one reason why setting several traps is better if you have access to them. If you don’t catch a mole within two days, then you should consider moving locations or resetting the trap. When you catch a mole, keep setting traps until you don’t catch them. Most homeowners have problems with several moles and not simply one mole.

For more detailed information about controlling moles, see Wildlife Conflict Management – Moles, Purdue Department of Entomology.

Wild Bulletin, Indiana Department of Natural Resources (DNR) Fish and Wildlife: Spring is the time anglers return to fishing on Indiana’s lakes and rivers. Often that includes catching and using live bait. Remember to dispose of all unused bait fish properly in the trash, as invasive carp could be lurking in your bait bucket. Improperly disposing of unused bait fish in a lake or stream could potentially allow invasive species, like silver carp, to spread in Indiana waters.

Invasive carp are a select group of cyprinid fishes (minnow family) that are native to Asia. The term “invasive carp,” formerly known as “Asian carp,” collectively refers to bighead carp, silver carp, grass carp, and black carp. Each of these species was intentionally introduced into the United States for different purposes; however, all are now considered invasive nationally and in Indiana. Invasive carp compete with native species and pose a threat to Indiana’s aquatic ecosystems.

Find out more about how you can help in the fight against invasive carp at DNR: Fish & Wildlife Resources.

Governor Eric Holcomb has proclaimed February 25th to March 2nd as 2024 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 cost 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 25th, 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.

Wild Bulletin, Indiana Department of Natural Resources (DNR) Fish and Wildlife: Indiana DNR has been working with neighboring states to address the invasive carp problem in our waters. The Kentucky Department of Fish and Wildlife Resources has been using contract fishers to harvest invasive carp from the middle Ohio River at the leading edge of invasive carp’s established population, and the Indiana Division of Fish & Wildlife provides support as needed. The contract fishing program will be operating through the winter and spring. Most fishing will occur from Leavenworth to Cannelton, Indiana, in small tributaries and backwaters off the Ohio River. Agency staff will ride along with contract fishers to collect data and ensure native fish populations are not negatively impacted.

Throughout the year, biologists are involved in several other collaborative research and monitoring projects to slow the spread of invasive carp within the Ohio River basin. If you encounter an invasive carp and are wondering what to do with it, try eating it! Our website includes information on how to clean and prepare silver carp for a tasty meal, as well as descriptions of other DNR projects that address invasive carp.

MyDNR, Indiana’s Outdoor Newsletter: Did you know that Indiana’s waterways can be altered by the presence of aquatic invasive species? Non-native plants, animals, and organisms can disrupt bodies of water and ecosystems, threatening sport fisheries and other commercial resources.

If you’re wondering what you can do to help prevent the spread of aquatic invasive species, there are many easy steps that Hoosiers and out-of-state visitors can take to stop aquatic hitchhikers:

• Clean off any animals, plants, and mud from any angling or boating gear.
• Drain the water from watercrafts, bladder tanks, bilges, motors, livewells, and portable bait containers before leaving the water access area.
• Make sure everything air-dries for five days or longer or is dried with a towel.
• Dispose of any unwanted or unused bait, fish parts, and packing materials in the trash, rather than on the ground or in water. Remember, littering harms the environment.

DNR is counting on you to help protect Indiana’s waterways and species.

MyDNR, Indiana’s Outdoor Newsletter: Do you have bats roosting on your property? Help DNR by counting how many bats fly out during a few evenings this summer. Monitoring bats as they emerge from roosts helps us manage the reproductive health of bats across the state.

The Summer Bat Roost Monitoring Project uses volunteers to collect information on the distribution, occupancy and abundance of bat colonies throughout Indiana.

Participants must have bats roosting on their property or permission to enter property where a roost occurs. Possible roost sites include trees, bat houses, barns, attics, outbuildings and other structures. On each night of surveying, volunteers count the bats that exit the roost and record weather information. Each survey takes about an hour and is conducted on eight to 12 nights from mid-May to mid-July.

Newsletter can be found online May: DNR: Communications: MyDNR Email Newsletter (in.gov)

For more information please visit Summer Bat Roost Monitoring Project.

To sign up for the project, visit the Division of Fish & Wildlife’s volunteer page and select “Find an ongoing service project.” Wildlife Diversity staff also monitor bats using mobile acoustic surveys and acoustic monitoring stations.

Wild Bulletin, Indiana DNR Fish & Wildlife email newsletter, Help stop the spread of aquatic invasive species: DNR and several Indiana conservation organizations gathered to take part in the fourth annual Great Lakes Aquatic Invasive Species Landing Blitz from June 24th to July 10th. Staff and volunteers were at state parks helping boaters, anglers and other water enthusiasts check their watercraft and other equipment for aquatic invasive species, along with educating them on preventive measures.

Aquatic invasive species are plants, animals, and other organisms that are not native to Indiana waters and have the potential to cause harm. These species are concerning because they outcompete native species, threaten human health, change and degrade the ecosystem, and/or require intense maintenance and monitoring.

Most invasive species find their way to Indiana through human behaviors. Modern transportation brings goods including invasive species from all around the world in a matter of hours or days. Some exotic pets or plants used in aquariums or water gardens escape into the wild and if they are adapted to Indiana’s conditions, they can become invasive. Boats and ships moving from waterbody to waterbody can spread invasives. Some invasives were brought to the U.S. intentionally as bio-controls for other invasives; others were introduced as game or food species.

Invasive species can be very expensive or impossible to control. For instance, Indiana spends an estimated $1 million per year in public waters to chemically control Eurasian watermilfoil, an invasive water plant that can shade out native species and interferes with boating and fishing. The damage to sport fisheries and commercial resources from AIS can be serious.

Illinois-Indiana Sea Grant Newsroom: Many Great Lakes communities that have carried the burden of legacy pollution for decades have an opportunity for a new lease on life when local waterways are finally cleaned up. A new video series features five cities along waterways deemed Areas of Concern (AOCs) that are in various stages of the cleanup process and are experiencing revitalization.

Historically, the Great Lakes region was a center of industry—steel, leather and lumber, to name a few—that eventually shut down or moved elsewhere as economies and priorities changed. Left behind in these waters was a soup of contamination, leaving degraded waterways and depressed communities.

In the United States and Canada, dozens of sites were identified as AOCs in the Great Lakes Water Quality Agreement, and over the years, many have undergone remediation.

The U.S. EPA Great Lakes National Program Office (GLNPO) has provided leadership throughout the cleanup process, which involves dredging or capping contaminated sediment. Even before the cleanup and subsequent restoration, local agencies and organizations have a seat at the table to discuss processes and priorities.

Funding is often a partnership between the federal government, in the form of the Great Lakes Legacy Act (now through the Great Lakes Restoration Initiative), and state, regional and local stakeholders.

The videos feature five cities—Duluth, Minnesota; Muskegon, Michigan; Sheboygan, Wisconsin; Ashtabula, Ohio; and Buffalo, New York—that have had some or all of their contaminated sites cleaned up and ecosystems restored. Local government representatives, business owners and residents share the impact of this work on recreation, tourism, economic development, housing and quality of life in the area.
