Des Moines Register: An invasive earthworm native to east Asia that was discovered in Iowa in 2018 has now spread to at least 11 counties. Officials in Dubuque and Muscatine counties were the first to report finding jumping worms, which are also known as crazy worms or Alabama jumpers due to their vigorous writhing and wriggling when disturbed. A map released in April by Iowa State University Extension and Outreach showed that the worms have now been found in Polk and Story counties, as well as Buchanan, Clayton, Jefferson, Johnson, Linn, Scott and Winneshiek. The ISU Extension website notes: “We assume jumping worms are much more widely spread than reports indicate.”
