>>Why should honeybee-recruits need anything more than odor?

Honey bees certainly have exceptional 'noses' but can they smell a 
solitary stand of blooming linden a mile away, say, downwind?

>>Flying insects in general, including solitary insects, can find 
sources of attractive odors in the field by use of nothing other than 
odors.

But solitary pollinators don't communicate with each other.

>>Scouts certainly carry back to the swarm the odors of the 
prospective nest-site they inspected. But, each individual scout 
naturally carries odors only from the specific site it had itself 
inspected.

While this may be possible, I'd love read some good references on 
this.
