Results are reported of a 3-year sampling study in permanent pasture and roadside vegetation. The snail has an annual cycle, breeding from autumn to spring, and being most abundant in pasture in spring, roadside vegetation in summer. Shell size and banding patterns vary geographically, but not with climate; size is inversely related to population density. Warm, moist condition advanced growth and morphological, but not reproductive, development.
