Jumping worms (Amynthas spp.) are an invasive species native to eastern Asia. In fact, no earthworms are native to Minnesota. Jumping worms contribute to major forest ecosystem disturbance and are also troublesome for homeowners and gardeners. They negatively impact soil structure and reduce plant growth.

How to identify jumping worms. It is important to properly identify invasive jumping worms before beginning to remove them from your yard or garden. Thankfully, Asian jumping worm adults are pretty easy to distinguish from their more harmless European cousins. Common earthworm. Photo: courtesy Joseph Berger, bugwood.org Appearance

2021年4月22日 · The highly invasive jumping worm, a genus introduced from eastern Asia, now writhes within the topsoil of more than a dozen states in the Midwest.

2023年2月2日 · Jumping worms are sometimes referred to as crazy worms or snake worms. On the surface, they look like any old worm. But as soon as they are disturbed, all of them share the same hard-to-miss trait. Instead of inching forward like a common earthworm would, jumping worms wag their bodies back and forth like a snake.

Jumping worms are known as epi-endogeic earthworms, that is, they live at or close to the surface. Most years and under normal conditions, they do not burrow deeper than 4 inches. However, this is dependent on soil type and duration of invasion. Adults and eggs can be found deeper than 1 foot in some circumstances.

2023年3月22日 · Jumping worms, also called crazy worms, are a relatively new invasive species from Asia but are rapidly spreading across the United States. They can be found in the Southeast, along the Eastern Seaboard, and in the mid-Atlantic, Midwest, and some Northwestern states.

Jumping worms are a type of earthworm. They are called “jumping worms” because of their unusual behavior when disturbed – they move like a snake and sometimes appear to be jumping. A light-colored ring extends around the body and is closer to the head than in other earthworms.

2024年10月17日 · “Jumping worms” encompass three similar-looking non-native, invasive species. The worms thrash wildly and move in a snake-like manner; their feeding produces granular castings that look like coffee grounds on the soil surface.

2024年1月22日 · The jumping worms alter the structure and chemistry of the soil dramatically, leaving a distinctive grainy soil full of worm castings, and they can damage lawns, landscapes and even the forest understory habitat.

2022年4月22日 · An international team of researchers, including Callaham, also reviewed what is known about jumping worms in North America, including their biology, impacts and the history of how they arrived in the U.S.
