What are Mason Bees?Up close look at a mason bee. Pioneer Pest Management, serving Portland OR and Vancouver WA explains what you need to know about mason bees.

Mason bees (genus Osmia) are solitary bees common throughout most of the United States. They’re generally metallic blue or blueish-black in color and are smaller than honey bees. Mason bees get their name from their habit of using mud or other masonry materials to construct their nests.

What Makes Mason Bees Different?

There are many habits and characteristics that make mason bees so different from many other bees. First of all, they’re solitary. While some bees form hives and support a queen, mason bees work alone and nest alone.

Mason bees don’t live in a hive. Mason bees look for small tube-shaped holes and create sections to place pollen and eggs in, sealing them off with mud.

Mason bees are not aggressive. The males do not even have stingers so stings are very rare.

Mason bees don’t make honey. Since they don’t live in social hives and are short-lived, mason bees don’t need to create stores of food. Instead,they eat pollen and nectar as they forage.

Mason bees are very prolific pollinators. In fact, they’re about 120 times more efficient at pollinating than honey bees. This is because of their somewhat messy pollination process. Honey bees gather pollen, mix it with saliva, and store it in their pollen baskets on their legs whereas mason bees haphazardly land on flowers, gather pollen all over their bodies and drop it as they fly away.
