Abstract
Angiosperm pollen dimensions range from 5–210 with a mean of 34. Pollen transported by bees as dry grains has similar dimensions. Pollen grains ≤100 and ≥ 10 constitute less than 4% of the total. Bees have evolved specialized hairs to collect and transport extremely large, extremely small, and tangled (interconnected) pollen, as well as oil. Specialized pollen- and oil-bearing hairs have evolved independently in various groups of bees and do not reflect the phylogeny of bees. Although the size of angiosperm pollen has influenced the morphology of bees, there is no evidence that the latter has influenced the former.
