Pinus strobus is a wind pollinated evergreen, and therefore does not offer much resources to honey bees. However, it is important to be able to identify Pinus pollen, because honey bees in food deserts, or with severe shortages in nectar and/or pollen rewards will resort to collecting Pinus pollen, and other wind-pollinated pollens.
