Brahminy worms (Ramphotyphlops braminus) are a tropical species of snake, so what the heck are they doing way up in Minnesota? Yard & Garden Line News has the story. Biologists think they hitchhiked over in the soil of a potted plant. The Asian snakes are established in Florida and Hawaii but are not thought to pose a threat in Minnesota, because it would be difficult for them to survive the chilly winters. Unfortunately the reptiles are parthenogenetic, meaning that they don't need males to reproduce.
