‘Extremely active’ jumping worms that can leap a foot raise alarm in California

Earthworm native to east Asia and known for its large appetite poses threat to forest ecosystems, scientists say

An invasive worm species known for its voracious appetite" and ability to jump a foot (30cm) in the air is raising alarm in California, where scientists have expressed concerns about the threat the worms pose to forest ecosystems.

The Amynthas agrestis, also known as the Asian jumping worm, Alabama jumper or crazy snake worm, have been spotted in California in recent months. The earthworm is native to east Asia, particularly to Japan and the Korean peninsula. However, in recent years the worms made their way to North America via various landscape plants that have been imported from the region.
