As the common name suggests, Asian jumping worms (Amynthas spp.) seem to jump or thrash when handled. Little kids and worm lovers might be excited by a find like this in their lawn, garden or woodlot but finding this worm is not beneficial for the native environment.

Why Jumping Worms Are A Problem
Most worms that you find in the Midwest are European and Asian non-natives. Both of these non-native types alter the native environment, although Asian jumping worms do it at a more alarming rate.  Jumping worms grow twice as fast, reproduce more quickly, and can work through organic debris much quicker than other worms. These invasive worms can severely damage the roots of plants in nurseries, gardens, forests, and turf. In areas of heavy infestation, native plants, microorganisms and animals such as salamanders may decline.

Asian jumping worms are an annual species; the adults die after the first freeze. But the cocoons, which are about the size of a mustard seed and resemble small pieces of dirt, will survive the winter and hatch when temperatures reach 50°F for a consistent period. These self-fertilizing worms do not need mates and can produce cocoons on their own. Because populations can grow faster than the common European species, they may out-compete existing worm populations. Cocoons can be spread easily in potted plants, on landscaping equipment, mulch, tire treads, and even hiking boots.
One telltale sign of an infestation is a very uniform, granular soil created from worm castings that are commonly said to look like coffee grounds. When you scratch the top layer of soil you will see the worms thrashing about with an erratic, snakelike movement. These worms, which can reach 6 inches in length, are much more active than European nightcrawlers. The Asian jumping worm can be found on the soil surface and in the leaf litter, making them easy to find. They can live anywhere from urban parks and suburban backyards to rural forests. You are also very likely to find them in compost piles and along roads.

Earthworm species have a body part called the clitellum where egg cocoons are produced. The Asian jumping worm has a prominent clitellum that completely encircles the body, is milky white to light gray, and is flush with the body; the body looks metallic. On European nightcrawlers, the clitellum is raised or saddle-shaped and reddish-brown in color and does not wrap entirely around the body.

Management
There is no magic control for these worms once they are found in soil. Asian jumping worms can now be found in the East, Mid-Atlantic, Midwest, and some Northwestern states. Prevention is the best way to keep them from being introduced to new areas. According to Wisconsin Department of Natural Resources, the following steps will reduce the spread of jumping worms:

• Educate yourself and others to recognize jumping worms
• Watch for jumping worms and signs of their presence
• Arrive clean, leave clean. Clean soil and debris from vehicles, equipment and personal gear before moving to and from a work or recreational area – they might contain jumping worms or their cocoons
• Use, sell, plant, purchase or trade only landscape and gardening materials and plants that appear to be free of jumping worms
• Sell, purchase or trade only compost and mulch that was heated to appropriate temperatures and duration following protocols that reduce pathogens.

According to Ohio State University Extension, much is unknown about the long-term effects of these worms, with research currently underway regarding control strategies in different environments.  Inorder to understand and track the presence of these worms OSU has developed a reporting site where Ohio gardeners can document locations of suspected populations. Gardeners should visit [ https://go.osu.edu/asianjumpingworms ] to report suspected locations and upload photographs.
​
Until effective research-based control strategies are developed to keep populations of this worm in check, gardeners should closely examine soil, compost, wood chips, and other soil amendments they move on or off their property. Learn how to identify these worms and educate your gardening friends and neighbors so they too can identify these worms.  If you do find these worms on your property, never share plants or soil with other gardeners.

Citizens are urged to be careful not to bring the Spotted Lantern Fly (SLF) home with them as a hitchhiker. People driving out of state or to parts of Ohio with known infestations should inspect and/or wash their vehicles upon return to ensure these insects have not accidentally traveled back with them.

Spotted Lantern Fly (SLF) which is an invasive plant hopper that is native to China was found in Pennsylvania in 2014. In late 2020, SLF was found in southern Ohio in Mingo Junction and in northern Ohio, Cuyahoga County in 2021. It is a major pest of crops including grapes, apples, hops, walnuts and hardwood trees. Nymphs and adults prefer to feed on the invasive tree of heaven (Ailanthus altissima) but can feed on more than 70 plant species, and has the potential to greatly impact the viticulture, tree fruit, nursery, and timber industries.
The insects suck sap from stems and branches which can weaken and damage the plant. The feeding can result in oozing sap, wilting, leaf curling, and dieback. In addition, during feeding the SLF secretes honeydew which can buildup on and underneath the plant, which in turn promotes the growth of black sooty mold.

Black sooty mold around the base of plants or oozing sap may indicate the presence of the spotted lanternfly, however other pests can cause these symptoms as well. Black sooty mold is harmless to people however it causes damage to plants. In counties infested and quarantined for spotted lanternfly, residents report hundreds of these insects that affect their quality of life and ability to enjoy the outdoors during the spring and summer months. Spotted lanternflies will cover trees, swarm in the air, and their honeydew can coat decks and play equipment.

SLF will lay eggs beginning in October through the beginning of winter. The egg masses of the SLF are small, grey masses protected by a waxy covering. After hatching in late spring, the SLF goes through four nymph stages. During the first three they appear black with white spots, and in the last stage, which typically occurs during mid-summer, they are red with white dots and black stripes. During the late summer and autumn, the SLF is in the adult moth stage. These adults are larger (approximately 1 inch), with black bodies and brightly colored wings.

Spotted lanternfly, which likely arrived on imported goods from Asia, is a plant hopper and not a strong flier. It is moved greater distances by people moving infested materials. It lays eggs on almost any surface, including vehicles, trailers, outdoor equipment, patio furniture, etc. Egg masses can be removed by scrapping with a hard or rigid tool and disposed of into a container of rubbing alcohol.
Early detection is critical to prevent economic and ecological losses. The public has played a key role in detecting spotted lanternfly and the success of stopping its spread depends on help from the public to look for and report signs of the pest.

If you suspect a spotted lanternfly infestation, at any life stage, please report the finding to the Ohio Department of Agriculture Plant Pest Control (614-728-6400, plantpest@agri.ohio.gov), your local OSU Extension specialist (https://extension.osu.edu) or by using the Great Lakes Early Detection mobile reporting app (https://apps.bugwood.org/apps/gledn/).
