The Asian Jumping worm (Amynthas spp.) has been found along the 1-5 corridor in Oregon and even in some gardens here in Eugene. Also known as the Asian Snake worm, the Asian Jumping worm is native to Japan and Korea, and can survive in a variety of habitats. It is easy to distinguish from other worms, based on its smooth light colored clitellum, large prostomium and somewhat iridescent appearance. The most obvious sign that distinguishes them is that they jump!

There is still a lot to learn about the Asian Jumping worm, but there is concern they may out-compete native species of worms. They also bio-accumulate hazardous levels of mercury and cadmium, and if consumed in large numbers by birds, frogs or salamandars, they may be toxic.

Asian Jumping worms can spread when used as fishing bait if the leftovers are discarded. The soles of shoes can carry cocoons from one area to another, or transporting soil that has worms or eggs from one place to another can also spread the worm.

To prevent spreading the worm or their eggs, be careful who you buy your fishing worms from. These invasive worms are being online sold as fishing bait. Clean your garden tools and shoes after working in your garden; avoid moving and sharing soil, mulch or compost from one garden to another; and inspect purchased plants before planting.
