Pollen Load Identification

The pollen of Aesculus spp. is known to cause a lot of dusting on the body of the foraging bee. Typically, the Aesculus spp. pollen creates a dusting on the posterior thorax, and the posterior and anterior abdomen of the foraging bee. Pollen has also been noted on the wings of bees visiting Aesculus for nectar instead of pollen.
