[2] They are commonly called sweat bees (especially the smaller species), as they are often attracted to perspiration.

In still other experiments, Menzel explored the timing of bee color learning by testing whether bees register color before, during, or after receiving their sugar-water reward. For this purpose Menzel displayed the color beneath a rewarded dish at different stages of the honey bee feeding process: during approach, feeding and departure. [2]

If the bees see the colored card as a shade of gray, then they will confuse the blue card with at least one of the gray-toned cards; bees arriving to feed will visit more than one card in the array.
The bees whose nests are exposed to the sun and heat build vestibules more frequently.
