Thank you for this wonderfully informative posting, which I shall save for
future reference.  I am curious about one assertion however:

It seems to me that this conflicts with the observation that when a hive is
moved at night and placed in a new location within normal foraging range of
the original location, foragers often return to the original site rather
than to the new site.

I'd like to hear your comments about that.

Frank.
