A 4-yr blacklight trapping project involving 18 trapping sites was conducted in Kansas. From 1996 through 1999, six species of Cyclocephala were recorded: Cyclocephala borealis Arrow, Cyclocephala hirta LeConte, Cyclocephala longula LeConte, Cyclocephala lurida Bland, Cyclocephala melanocephala (F.), and Cyclocephala pasadenae (Casey). Cyclocephala pasadenae and C. lurida were the most plentiful species (132,915 and 93,799 specimens, respectively) with the former being most dominant in western Kansas, and the latter dominating eastern Kansas. Cyclocephala borealis was most concentrated at the southeastern trapping site. The highest concentrations of C. longula and C. hirta were in a pocket of counties in southcentral Kansas. Whereas C. hirta and C. melanocephala were captured only in 1999, all other species were active during each year of the study.
