"Invasive Asian jumping worms got their name because of the way they thrash around," Forest Service researcher Mac Callaham said in a post by the USDA last year. "They can flip themselves a foot off the ground."
article says they consume organic matter and make the soil worse for plants, not better.
keep an eye out folks. I don't think they're dangerous to people at least.
