Starvation plus varroa. Colonies heavily infested with varroa often don't
break cluster, move to over head honey stores. I saw this in a major
study we did with mites in the 80s. 2nd story full of honey, colonies with
highest levels of varroa starved.
This can also happen in very long period of cold - if the bee cluster in
the lower boxes is shifted laterally, so that the honey in the second story
is not directly above the cluster. Cluster doesn't break enough to shift
from side to side. Starves.

Bill: That is still consistent with starvation.<<
