What I mean by not reproducing is that the VJ enters the cells of brood of
the EHB and does all the "normal" varroa things but does not lay eggs.  The
trigger is not there to induce the female to lay.  These are not old mites
but young females.

There is a difference in appearance.  I would refer you to the original
paper by Dr. Denis Anderson for more details.  Anderson, D.L. & Trueman,
J.W.H. (2000) Varroa jacobsoni (Acari:Varroidae) is more than one species.
Experimental and Applied Acarology, 24, 165-189.
