I occasionally get comments to old entries, and recently I've gotten two to my 365 urban species post about the wandering broadhead planarian, affectionately known as the "landchovy" by my readers. This terrestrial flatworm is an predator of earthworms, an alien native to Indonesia or thereabouts, accidentally introduced into North America in exotic plants(probably). It was first detected in the middle of the continent (I want to say the Chicago area, but I forget exactly) and has spread, or been introduced to, both coasts and just about everywhere in between. I found several in Boston, which may be about the northernmost extent of their range on the east coast.
