A comparative study was initiated to determine if habitat influences the abundance and richness of nitidulid beetle fauna at three sites (Kent Bog, Tinkers Creek, and Gott Fen) managed by the Division of Natural Areas and Preserves of the Ohio Department of Natural Resources. These sites in Portage County were sampled from early May through late October of 1990. Six sampling techniques were used at each site: Skalbeck traps, windowpane traps, Japanese beetle traps, gallon jug traps, greenhouse flat traps, and carrion traps. Baits included: whole wheat bread dough, fermenting brown sugar, cantaloupe, carrion, and banana. Most frequently collected nitidulid species were Stelidota getninata (Say), Glischrochilus quadrisignatus (Say), G. fasciatus (Olivier), and Carpophilus lugubris Murray. At these three sites, several species of nitidulids appeared to be rare: Glischrochilus obtusus (Say), Glischrochilus sanguinolentus rubromaculatus (Reitter), Carpophilus hemipterus (L.), C sayi Parsons, Cryptarcha concinna Melsheimer, Cryptarcha strigatula Parsons, Colopterus maculatus (Erichson), C. semitectus (Say), Cychramus adustus Erichson, Epuraea helvola Erichson, E. rufa (Say), Prometopia sexmaculata (Say), Pallodes pallidus (Beauvois), and Phenolia grossa (Fabricius). Kent Bog appeared to have the greatest overall diversity of nitidulid species, followed by Tinkers Creek and Gott Fen. Species composition appeared to be most similar between Kent Bog and Tinkers Creek. A total of 30 species were collected with all attractants. Of these, 24 species were taken at Kent Bog, 15 species at Gott Fen, and 21 species at Tinkers Creek. All species are new records for Portage County.
