Nitidulidae and Kateretidae represent two closely related, taxonomically and ecologically diverse groups of beetles. For the first time, a comprehensive survey of Wisconsin Nitidulidae and Kateretidae was initiated in 2000 and will be completed in late 2002. Sites for collecting and trapping of specimens were selected based on the habitat type and lack of species records. Flight intercept traps and 12-funnel baited Lindgren traps were the main methods of trapping. The baits used with the Lindgren funnel traps were fermenting brown sugar, fermenting whole wheat bread dough, and rotting fruit. These methods proved to be a simple, yet effective method for collecting specimens. Hand collecting proved to be extremely valuable in obtaining biological information on fungal, flora, and other associations, such as ant and carrion, rarely documented with these beetles. Utilization of literature records, museum and private collections, and field research has yielded 75 species, about half of which are new state records. From these findings, taxonomic identification keys, illustrations/photographs, species profiles, distribution and natural history information will be provided for Nitidulidae and Kateretidae for the first time in the Great Lakes region and for the United States.
