The consistency of this made me curious, and an anecdotal observation is that those clusters heavily infested were further from the center of the brood (cooler?) than those clusters closer...by at least a frame, often two. By the third round of this in a colony (after 60 some days) this went away, but if any varroa remained, they were in the clusters farthest from the center (which by now may be those locations that at one time were closer), which by now had moved...again, anecdotal on not many 8 frame colonies, in northeast Ohio.
