To All: A flurry of messages dealt with how to mark bees and other animals. A book that should be of help in this matter: Kearns, C.A. and Inouye, D.W. 1993. TECHNIQUES FOR POLLINATION BIOLOGISTS. Univ. Press of Colorado. Starting on p. 321, one can find a number of techniques, including mention of the paste on disks already provided on the internet.
