Amynthas spp. (CABI)
Asian jumping worm, Asian crazy worm, Alabama jumper
East-central Asia (Laushman et al. 2018)
Present in the U.S. since the late 1800s, but has been recently invading natural habitats in the Northeast and Midwest (Laushman et al. 2018; Schult et al. 2016)
Possibly through the horticultural trade or by anglers using them as bait (Snyder et al. 2011)
Affects forest habitats by altering soil properties, resulting in reduced food resources for native species (Schult et al. 2016)

What could be more 2020 than an ongoing invasion of jumping worms? These earthworms are wriggling their way across the United States, voraciously devouring protective forest leaf litter and leaving behind bare, denuded soil. They displace other earthworms, centipedes, salamanders and ground-nesting birds, and disrupt forest food chains. They can invade more than five hectares in a single year, changing soil chemistry and microbial communities as they go, new research shows. And they don’t even need mates to reproduce...

Imagine walking through a forest, with leaves crunching beneath your feet. Underneath those crunchy leaves is a complex ecological realm. “Soil is teeming with life,” says U.S. Forest Service research ecologist Mac Callaham. “Most people don’t think about it because they don’t see the soil fauna.” Soil fauna includes centipedes, millipedes, springtails, nematodes, insect larvae, and earthworms. “Springtails are very small arthropods,” says SRS ecologist Melanie Taylor. “Earthworms are the giants of soil fauna.” Taylor, Callaham, and lead author Meixiang Gao recently published a study on non-native earthworms and the food web. The study was published in the journal Soil Biology and Biochemistry.
