Basically plants have coevolved with these pollinating insects. Plants that can develop the best pollen that sticks to these insects are able to reproduce more successfully. While bees, as the example, are collecting it as there food. Bees are not “helping” the plant knowingly, its more of the plant is hitching a ride.
Possibly when furrier bees evolved, it could be that the fur was protecting them from harsh weather conditions and allowing them to fly further and making it to more flowers. The fur builds electrostatic forces as the bee went along with its day. Serving another beneficail purpose by attracting more pollen to stick onto their bodies. The bees also use the fur to wipe pollen from their eyes and off their legs.
Essentially furrier bees were more successful at feeding their offspring than non-fur bees. Which was selecting for even furrier bees in the following generations continuing to the furry honeybees we see today.
