Phil,
 
I think you hit the nail on the head when it comes to the visualization.
Last year, I remember my wife and I needed to move a hive over a few meters.
She wanted to do this at dusk because by then most of the bees were in the
hive.  I didn't know what that meant until we jostle the hive a bit as we
were doing the move.  As you expect, quite a few bees came out to see what
the heck was going on.  As we got the hive settled in the final spot, I
walked back to the area where it was and found quite a few flying around in
circles trying to find the hive that was once there.  It was absolutely
amazing to watch.  Needless to say, we lost quite a bit of workers from
that.
 
Brian

Tom,

I ain't no bee expert but I do know that bees navigate by visual cues.  When
a bee leaves the hive for the first time it flies backwards and takes mental
"snapshots" of the hive and the surrounding area.  It is easy to confuse
bees by moving rocks and other objects near the hive.  And if you move the
hive six feet the bees will congregate around the old spot and may not be
able to find the new location.  I think I read once that bee vision is poor,
not because the compound eye is deficient, but because the bee brain is so
small that it lacks the processing power to handle all the visual input.

But it is possible that the bee continues to take mental snapshots as it
ventures farther and farther from the hive.  If you hand carried a bee to a
location it had never been before, I would think it would be likely that the
bee wouldn't know where the hell it was.

On a related subject,  my bees are very sensitive to sounds.  They get angry
when I mow near the hive with the little high pitched lawn mower but they
don't seem to mind the deeper sound of the tractor with its big mower.
Needless to say the trees in that section of the orchard don't get mowed as
well as elsewhere.

Hi,

Dumb question...

How do bees navigate away from the hive, and then return to
it?

I know that they do a dance in the hive which tells other
bees where nectar can be found, which I believe has to do
with the position of the sun in the sky.

But would the bees you hand carried to the plants be "lost"
and not know the way back to the hive?

Since hives are moved around to pollinate crops, the bees
must have some means of remembering where the hive is on a
daily basis.

Hopefully, a bee expert will be able to reveal how dumb this
question is.

Regards,
Tom

Hi,

sky.

Brian:
     I have kept bees for over 20 years, and have learned this about
them: each bee only works one type of flower at a time.  Your bee kept
returning to the dandelion because she had been assigned to dandelions.
    That said, my bees have never been too gung-ho for strawberries.
What pollination takes place on strawberries seems to be done by
smaller, feral insects.  They must not have much nectar or other
attraction for classic bees.  Even so, I have never noticed that
strawberries fail to set due to lack of pollination, so they may be, to
some extent, self-fertile, or they benefit from some air pollination.
