Hi Tom,

Varroa moves in mysterious ways!

More to the point, people do move varroa over vast distances; varroa
was introduced to Wales by beekeepers moving bees e.g. to the heather.
Having said that, it was only a matter of time before it reached us by
more natural means.

Introduction to Ireland was very probably via Wales! swarms are known
to travel via lorries on ferries, and could travel some distance into
Ireland before dropping off.

Only speculation, but does account for first discoveries in unexpected
places
