Peter asks<Are they not assisting the pollination by dislodging pollen  
from the male 
flowers, some of which will then drift onto the female  flowers?>


I've seen bees on sweet corn, and their activity was creating a  rainfall 
of pollen.  
 
Whereas I've seen bees collecting pollen from sweet corn, I've never  seen 
more than an occasional bee on field corn.  Tom Hamilton, an Idaho/MT  
beekeeper said that he's seen bees on sweet corn.
 
I've seen bees collecting pollen from grass during our dry season,  and we 
found pollen from rushes and reeds in bee-collected pollen near cooling  
ponds by the Hanford nuclear reactors before they were shut down following the  
Chernobyl incident.
