Mason bees are better pollinators than honey bees!

"Mason bees work faster, darting from flower to flower at a much quicker rate than honey bees. Although honey bees can fly very fast in a straight line, when they are working flowers, they tend to dork around and take their time. Try taking pictures of both, and you can feel (and see) the difference.
Lastly, the pollen on a mason bee’s body is held loosely. They have hairs for collecting pollen on their abdomen (called a scopa), and also on their face. They use their legs to push pollen into the scopa where individual pollen grains can easily rub off onto the next flower, allowing pollination. Honey bees, on the other hand, have a pollen press on each hind leg. The honey bees moisten the pollen with nectar and then press it into the pollen baskets on each leg. This pollen — wetted and pressed — is like dough. It is unusable for pollination because it won’t rub off onto the next flower." For the sake of the honey we still like honey bees!
Yes I learned about them years ago, a documentary on youtube. Hubby used to keep 4 honeybee hives years ago. Mason bees are better pollinators. We have no mud that I know of. When I hung the house I wanted to find a few shovelfuls of clay mud but never got around to it, after a week I looked and the tubes were filling up, even watched a bee going in. I just got done sewing a bag out of organza. Found out when storing the house for the winter it needs to be bagged to keep out mites.
