Hereís the distribution of numbers of flowers available per raceme from the
same fields at the same time as the bees were being followed.
There are many more flowers per raceme in bloom early in the season than late
in the season. Bees clearly donít visit all of the flowers available on
A similar change in distribution of numbers of flowers per raceme when
standing crop was high vs. low was seen in commercial fields. (see slide
We were able to generate the distribution of flowers visited by bees late in
the season (slide 21), by superimposing the 57%
movement rule on the late season distribution of flowers per raceme. Few
racemes have more than three flowers open. So, stay on the raceme 43% of the
time, but if there are no more flowers in bloom, the bee has to leave.
