As the bee reaches into the flower for nectar, its body becomesmore or less covered with the dusty or sticky pollen, and when it alightsupon the next flower of the same kind some of this pollen is almostcertain to be rubbed off on the stigma. This cross-pollination is thoughtfor certain reasons to be more advantageous than close pollination(pollination within the same flower), and the insects thru their visitsbring it about even in flowers that have both stamens and pistils.
