Triangulating from the cairns…
In the Rocky Mountains of Colorado, changes in the availability of floral resources through the growing season may affect the ability of bumble bee colonies to successfully complete their life cycle and produce reproductive individuals in the season’s end. A way bees could potentially deal with this challenge is by broadening their diets —visiting a wider variety of flower species for pollen and nectar. I investigated the diet breadths of three bumble bee species in that region at the species and individual levels, asking whether bee diet breadths varied with floral resource abundance. I found that at both the species and individual level, bees’ diet breadth does not seem to vary with floral resource abundance. Bees may have another strategy for dealing with a lack of floral resources, or their diet breadth may be constrained by other factors such as competition.
