Figure 5. Relative abundances of Clarkia pollen on pollinators.Clarkia present in a pollen ball were weighted by their relative
abundance in the sample and then summed to yield a value for that
species’ relative pollen contents for each pollinator. Larger bars
indicate higher pollinator counts, where Lasioglossum pullilabrewas the most frequently caught pollinator, followed by Hesperapis
regularis, Lasioglossum (Dialictus) sp., and Diadasia
angusticeps.
