> I have seen bees removing brood from cells before, but have thought it due
to mites visible on the brood.  On these ejected brood there were no visible
mites.

Larry, sounds like bees with VSH removing pupae.  You won't see mites on the
brood--the mites leave.  But look on the cell "ceilings" to see if there are
guanine deposits, indicating that mites were in the cells.

If the pupae being removed are white, then is VSH.  If they are dark or
contain blackened areas, then they were likely dying from virus.
