I just read an Atlantic article about invasive jumping worms. What is known about them in Michigan and have you ever done an email about them? I am on your email list and enjoy your publications for the home gardener.
Wayne County Michigan
This was the first I had heard of these. A quick search of the internet found this article by Oakland University so they have been in Michigan since 2008. https://oakland.edu/biology/news/2017/ou-biologist-studying-spread-of-invasive-worm-in-michigan
I also found this fact sheet the Michigan State University - Applied Spatial Ecology and Technical Services Laboratory. Available online at https://www.misin.msu.edu/facts/detail.php?id=322.
