How embarrassing! My apologies to Bruzzi and the net. I should have directed my comment to John Bidleman, and I used "REPLY" without noticing that the result was addressed to the List. So beware! If you use "REPLY", your note may NOT go to the address shown in the "From:" line, because Listserv is configured (for BEE-L) to include the line, "Reply-To: Discussion of Bee Biology <[log in to unmask]>". (On the other hand, I was personally confused about who sent which note, when I directed my comment to Bruzzi Giacomo." Again, my apologies.) Regards, Dick [log in to unmask]
