Colletes clypeonitens Swenk
This is a common spring species of the Colorado and Mojave deserts of southern California and the Sonoran Desert of Arizona and is one of the most consistent Larrea oligoleges. Timberlake (1951a) states that it visits Larrea almost exclusively, but stray specimens have been taken at flowers of Cercidium and Encelia. In the collections at Riverside (Timberlake), Berkeley, and Davis, there are more than 80 separate samples from Larrea, with a high proportion of females bearing Larrea pollen in their scopae. We have found them present at all our spring sampling sites in Arizona and southern California, usually in large numbers. Dr. G. E. Bohart also obtained it in large numbers during his sampling program at St. George, Utah, in late May (Table 15).
