The habitat and courtship behavior of the wolf spider Schizocosa retrorsa (Banks 1911) were studied and are described here for the first time. The range of S. retrorsa was extended to include the lower peninsula of Michigan. This species is locally abundant in highly exposed habitats of sand or pine litter. Male courtship consists of chemoexploration, palpal drumming, an extended leg tap, and a "push-up" display. Female displays include a double leg arch, approaches, and orientations toward the male.
