Hi Mary & All, Apr 20, 2007
Perhaps so, but I suspect the bee keeper in question was out to
lunch. I don't recall ever seeing bees or flies on alder catkins, male
or female, nor on any of the Corylaceae, or Oaks. It has been my
understanding that any plant with a long pendulous male catkin is wind
pollinated whereas the relatively stubby catkins of Willow (at anthesis)
are worked by many kinds of insects.
Alternatively, am I out to lunch on this one ?
