Ive followed your thread with interest.
The data I reported were collected during the small cell study conducted at UGA several years ago. The cell size measurements were not a formal part of that study but were measured in a effort to verify the often stated idea that 4.9mm was the natural cell size for honey bees. While these data were not reported as part of that study Ive had personal communication with Jennifer Berry regarding them. Ive also heard her report these numbers when shes spoken at various meetings.
If it is important to you Id be willing to follow up with her to see if they are in any publicly accessible documents.
Best to you from another oldtimer.
