Barbara Kingsolver’s Flight Behavior (2012) is a contemporary narrative of climate change, which presents the interplay of rurality and cosmopolitanism. The novel describes the ways in which its heroine―a marginalized farmwife―evolves into a cosmopolitan citizen inasmuch as she tries to find a practical solution for climate change upon encountering the sudden arrival of the Monarch butterflies at the mountain right behind her house, which is a by-product of global warming. Over the course of the narrative, the farmwife opens her rural and domestic space to visitors from all over the world, working closely with them. Her change unfolds in ways that territorialize cosmopolitanism within the rural community. In this article, I examine the process of her development through the theoretical lens of rural cosmopolitanism. Ultimately, I argue that the novel prompts the reader to closely look at how one’s habits of everyday life in the countryside can be assigned cosmopolitical meanings in the twenty-first-century world risk society.
