Asters in the colloquial sense include several genera of fall blooming composites. At least two bee species have aster in their name and seem to be at least loosely assorted with the flower genera Doellingeria or Symphyotrichum, the later being one of the last native plants to bloom in the state.

See also the Goldenrod bee page, as there is nearly complete overlap in the species visiting these two groups of related plants.
