The Amynthas species we have in the US (most commonly Amynthas agrestis and Amynthas tokioensis) are primarily from Japan and the Korean peninsula. In their home habitats, they evolved along with the local ecosystems — and the ecosystems along with them. But here, “just like any other invasive species that are displaced into a brand new habitat that might not have controls, they’re able to take advantage of that and go gangbusters,” says Brad Herrick, an ecologist at the University of Wisconsin-Madison Arboretum.
