Hi Medhat,
   Thank you for your observations, and of course, you are
correct—butterflies and moths are specialists and not in direct competition,
on most plants, with honeybees. I knew the supposition was a reach (that
beekeepers would be affected).
   But I also feel that the information concerning the possible devastation
of a vast order of pollinators was significant enough that beekeepers should
be made aware of it. I find when I am working my hives or driving around in
my pickup with bee gear in the back, people often approach and ask questions,
so I feel—whether I want it or not—cast in the role of an educator. If the
public in the Northwest suddenly notices there are no butterflies or moths in
the fields, local beekeeps may be fielding questions about it.
   I worry about honeybees getting the blame for the afflictions of other
pollinators because a great many people probably don't know that bees,
butterflies and moths feed on different forage plants. If beekeepers have
accurate information about what is happening to the rest of the pollinator
populations, they will be able to disabuse people of any nascent prejudices
they may hold against honeybees.
Cheers,
John
