Mason bees are docile bees that emerge from their cocoons in the spring when fruit trees and many of our native shrubs and herbs are in bloom. Visiting up to 2000 flowers each day, these highly efficient pollinators increase fruit production as well as improve the overall health of their ecosystems by aiding the health of native plants. As a solitary bee, they have no queen to protect therefore no reason to sting. They are fun to watch throughout the spring and are a important member of our ecosystem.
