As to the orientation of the egg at the time of fertilzation:
 
It was my understanding that the reproductive tract was shaped so that the
micropyle is aligned exactly opposite the opening of the spermathecal duct
(Wigglesworth, 1953), and that muscular contractions press the egg up
against the spermathecal duct as it passes (Yakhontov, 1961).  However,
I believe this information applies to insects "in general".  How applicable
(Apisicable?) it is to bees ....
