I have followed all the advice a bit, and my first intuition still stands:
Flapping bee-wings appear as a blurred but *STILL* object, unless you plan
on using stroboscobic light effects, in which case it is not realistic
anymore. The only times something changes in the wings, is when the bee
settles on a flower to do some nectar-sucking etc. It changes (almost)
instantaneously to still wings. And when it is making a sudden turn in mid
flight, in which case it will just flicker a little for a fraction of a second.
This is based on lazy summers spent in the grass looking at bees and/or
bumblebees flying lazily by, or lazy summers spent swatting frantically at
carnivorous flies trying (and succeeding) to make a meal out of me.
Hope this helps (and maybe makes things easier).

Good luck with the bees.
