Focusing on the writing of Wyndham Lewis, D. H. Lawrence, H.D. and Samuel Beckett, this book uncovers a shared fascination with the aesthetic possibilities of the insect body - its adaptive powers, distinct stages of growth and swarming formations. Through a series of close readings, it proposes that the figure of the exoskeleton, which functions both as a protective outer layer and as a site of encounter, can enhance our understanding of modernism's engagement with nonhuman life, as well as its questioning of the boundaries of the human.
