This is hopeful news; where can I learn more? If this is true, then
either the bees are developing a degree of resistance, or the most virulent
strains of varroa are disappearing, or both. At a guess, I would imagine the
first is most likely to be true, because we know that bees are genetically
very variable, while a lot of arthropods and similar organisms are not, if
what I have heard is true. Sorry, I don't have a source for that.
Is there more information on the cell size used by different races
available anywhere? I currently have Italian/British black hybrids; I may
change to British black. I believe the old black bees used in the States were
similar to the German heath bee; is it true that these were inferior to the
British type?

This is really interesting, only I have a problem. I am unable to see
eggs, small larvae or varroa with my glasses on, and I cannot see anything
properly through a veil without them. My bees are rather dodgy-tempered, so I
don't want to go without the veil. Does anyone have any answer to this?
