Abstract
-Habitat distribution and seasonal occurrence of 64 species of Carabidae in E-central Minnesota were determined with pitfall traps during the growing seasons of 1980 and 1981. Species richness and total number of individuals trapped were determined for 10 sites differing in vegetation, moisture and soils. A lowland forest site had the highest species richness, steepest dominance-diversity curve and largest number of individuals trapped; upland forest sites had the most even distribution of species, and field sites were intermediate. Moisture was considered to be important in determining the composition and range of habitats where species occurred. Influence of different amounts of moisture on carabids between habitats and years, as well as effects of vegetation, ground cover and surrounding habitats is explored. Weekly trap data of adults and larvae provided new information on annual activity patterns and probable overwintering stages of several species.
