Some plants can only be pollinated by bees because their anthers release pollen internally, and it must be shaken out by buzz pollination (also known as sonication).
The flowers are pollinated by bees, which grab hold of the petals, and gather pollen by vibrating the flowers by buzzing their wings (buzz pollination).
Currently, there are several scientific organisations conducting thorough research on how the blue banded bee benefits agriculture through its distinctive buzz pollination.
