One hundred and one species of Carabidae, including Bembidion incrematum LeConte, Pterostichus caribou Ball, Amara lunicollis Schi0dte, Stenolophus rotundatus LeConte, and Lebia tnoesta LeConte, new state records, representing 32 genera were identified from light trap collections operated during 1984 and 1986-1988 in the open wetland, and from barrier pitfall traps placed in an adjacent swamp oak—hawthorn forest in 1992. Most species are hygrophilous. Species richness was highest in Agonum and Bembidion. Pterostichus hamiltoni Horn, P. permundus (Say), Bembidion graciliforme Hayward were the most abundant species collected by pitfall traps and Stenolophus ochropezus (Say), Agonum tenue (LeConte) and Clivina impressefrons LeConte were the most abundant in light trap collections. Differences in the number and abundance of species collected by light traps and pitfalls suggest both methods be used to survey wetlands.
