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)
