My apologies.
The article appears in October (2021) issue of The American Bee Journal, now protected by paywall, and I do not subscribe to the journal as I have never had. About a month ago, I was able to get one off the net without the paywall, but I could no longer. If any of you want the PDF version I had saved, I will send it as an attachment.
If any of you know how to get one free, please help.
