Porto Alegre, 12 September 1991
In the National Geographic article (vol 179, no 6, June 1991) by
Michael E. Long about "Secrets of Animal Navigation" there is a
photograph showing F C Dyer from Michigan State University brushing
honeybees with a pink pigment. Does anybody know what pigment it is
and where I can get it? Or does anybody have suggestions how to
make even smaller (stingless) bees more visible during flight?
Thank you.
