les, what moebees said about the numbers.
honeybees go for the blueberries primarily for the nectar, and as i understand it, they will 'drum' or 'vibrate' the anther to release whatever little pollen they can and inadvertently carry it from one flower to the next.
the bumbles and wild bees are the best at the buzz pollination, honey bees are a supplement, my understanding.
i think perry might be able to answer this question better than i can, can't remember if he did some blueberry pollination or not?
