Bees collect nectar for nutrition and they collect pollen as their protein source. These activities pollinate as a by-product. Honey bees collect a lot of nectar to refine into honey to survive the winter months. This makes the honey bee ideal for some flowering plants which have a lot of nectar that the honey bee needs. Many native species have short lifecycles. Some only during a bloom of a particular flower. This is why native bees make better pollinators as a whole. Honey bees pass up many flowers that have little benefit to them as a nectar source. Native bees collect the pollen that would be undisturbed by the honey bee.
