In response to you query on bee vision......I believe the first study
was von Frisch 1965, and more recently Rossel and Wehner in 1986, the  only
publication  referring to von Frisch is as follows...( I didn't really dig
to deeply into the literature)
Frisch, K. von. (1971).  Bees, their vision, chemical senses, and language.
Cornell University Press, Ithaca, New York.
 
also:
 
Rossel, S. and R. Wehner. (1986).  Polarization vision in Bees.  Nature
323:128-131
 
overall I would attribute the "discovery to von Frisch
Hope this helps...rather than clouds the issue
