Wisconsin?s newest invasive species, the Asian crazy worm, has been found for the first time on the University of Wisconsin campus, according to a release.
The UW Arboretum is the first confirmed site for Amynthas agrestis, an invasive worm believed to have come to the United States from its native Japan and the Korean Peninsula with plants imported for landscaping, officials said.
?Amynthas was listed as a prohibited species under Invasive Species Rule NR 40 since its adoption in 2009, because we knew their introduction into our state poses a huge threat to the future of our forests," said Bernie Williams, invasive species specialist in forest health at the DNR.
Williams and arboretum staff members found the worm in the fall of 2013, according to the release.
Arboretum ecologist and Research Program Manager Brad Herrick said they believe the worms' egg cocoons have survived the harsh winter.
