Mason Bees
The NatureScaping Wildlife Botanical Gardens features a native Mason bee demonstration shelter designed to introduce visitors to these remarkable (and very busy) native pollinators.
Mason bees are solitary native bees — just one of more than 4,000 native bee species in the United States. In the Pacific Northwest alone, Washington is home to over 600 species, with Oregon and Idaho each hosting more than 700. That’s a lot of tiny pollinators doing big work.
Unlike honeybees, Mason bees don’t live in hives or have a queen. Each female is a “queen of one,” building and provisioning her own nest. She uses mud to create walls between each brood chamber — which is how they earned the name “mason” bee. Think of them as miniature bricklayers with wings.
Mason bees are powerhouse pollinators. They carry pollen loosely on the underside of their abdomen (on special hairs called scopa), and as they visit flower after flower — often more than 2,000 blooms per day — pollen dusts everything in their path. Because the pollen is transported loosely rather than packing it tightly into a pollen basket as honeybees do, pollen is readily dislodged and effortlessly transfers between flowers. Mason bees can be up to 100 times more effective than honeybees at pollinating certain crops, especially fruit trees.
And the best part? They are calm and non-aggressive. While females can sting if squished or threatened, they rarely do. Mason bees are gentle, garden-friendly pollinators — our quiet spring neighbors.
Follow the main path through the Gardens. When you get to the shed, look to your right — the Mason bees’ tiny neighborhood is located there!
