Pollination Vectors

A question for plant ecologists and others interested in pollination 
vectors: How does one establish that an insect species found "hanging 
around" a particular species of flower in bloom is in fact a pollination 
vector for that plant species?

At the moment I'm interested in some speciation questions regarding 
Trillium in the Great Smoky Mountains National Park and vicinity. One 
question I want to look into is if there are differences in pollination 
vectors that might serve to help isolate two sympatric species to some extent?

At the moment, two of us have photographed what appear to be Drosophila 
(fruit flies) sitting on flowers of Trillium. Where do we go from here to 
try to establish cause and effect?
