Résumé
Three habitats (dunes, mountain slopes, and mud flats) were surveyed for bees (Hymenoptera : Apoidea) in the Bonneville Basin in Utah on lands owned by the U.S. military, the Dugway Proving Grounds and the Utah Testing and Training Range South, in the summers of 1997 and 1998. In 1997, bee species richness, distribution, and abundance were compared among the three habitats using yellow pan traps. The results revealed that these dunes are not unusually rich in bee species compared to surrounding habitats. However, the results did support the hypothesis that the most widely distributed bee species are also the most locally abundant. In 1998, I compared sampling effectiveness for bees using three different pan trap colors (yellow, blue, and white) to evaluate any possible biases from using only yellow pan traps in 1997. By combining both collecting years, 128 bee species were recorded from my study area.
