From 1999–2002, the University of Nebraska Department of Entomology, Folsom's Children Zoo, and Lincoln Public Schools Science Focus High School initiated a program called Bumble Boosters. Forty schools participated to conduct a general survey of Nebraska bumble bees to: 1) determine whether the 20 species of bumble bees previously identified can still be found in Nebraska, 2) collect in areas that were not included in previous surveys, and 3) discover any additional species in the state. This study provides an update to previous surveys including; new distribution maps for species, and a discussion of findings.
