We review the literature on the influence of landscape structure on butterfly distribution and movement. We start by examining the definition of landscape commonly used in spatial ecology. Landscape-level processes are reviewed before focusing on the impact of the geometry and spatial arrangement of habitat patches on butterflies e.g. the nature of the matrix, patch size and shape, minimum area requirements, immigration and emigration, and temporal habitat dynamics. The role of landscape elements is reviewed in terms of corridors (and stepping-stones), barriers, nodes, environmental buffers, and prominent landmark features.
