When Endless Thread producer Nora Saks learns that a "toxic, self-cloning worm that poops out of its mouth is invading Maine", she starts sounding the alarm about the impending eco-doom.

Until, that is, state experts clue her into the "real threat"; a different creepy crawly wriggling towards The Pine Tree State's gardens and precious forests, and fast. 

In an attempt to find out more about this real threat, co-hosts Ben Brock Johnson and Nora Saks tunnel down a wormhole, encountering a long history of xenophobic rhetoric about so-called invasive species, and some hard truths about the field of invasion biology itself. Eventually, they wind up at a community garden in Bangor, Maine, where the worm wars are playing out in real time. 

This Endless Thread episode is about invasive species in our midst, and more importantly, the stories we tell about them.
