I finally found a Rudbeckia that Honeybees like!
For the most part they're pollinated by tiny bees, hover flies and almost nothing else. As far as pollinator plants go they're pretty boring. I believe it has to do with the fact that they're short lived. Rudbeckia subtomentosa is a longer lived perennial falling somewhere in the middle between the two species above and the one I'd like to focus on below.
Rudbeckia laciniata, is a perennial species that spreads by rhizomes to form a dense clump.
Much to my surprise this one plant is getting more honeybee attention than the patch of Cup Plants, Silphium perfoliatum, which is eight times bigger, twice, as high, and covered in flowers.
The Rudbeckia laciniata is attracting quite a bit more diversity too than either the other Rudbeckia speices, or Cup Plants.
