Mason Bee Cocoons brought home yesterday, Saturday, March 18 2023

 Mason bees are powerhouse pollinators, visiting many flowers in a short amount of time and carrying enormous amounts of pollen on their bodies. Studies have shown that 250 to 300 mason bees can do the equivalent work of 90,000 honey bees (Apis). Bees in the genus Osmia fashion their nests in preexisting holes and cavities – some natural, such as hollow plant stems, while other times they rely on cracks and crevices in stone and brick (masonry) walls. At least one species, Osmia bicolor, constructs its brood cells in abandoned snail shells! Mason bees mark the entrances to their nests with a scent that is unique to them.

Say hello to a Mason Bee. Mason bees in the genus Osmia are a diverse group of solitary bees known for their important role in pollination. With over 300 species worldwide Osmia bees are distributed across all continents except Antarctica. There are over 100 species of mason bees in North America! They are commonly found in a variety of habitats ranging from deserts to forests. As cavity nesters, Osmia construct their nests using natural or manufactured cavities such as hollow plant stems, insect tunnels, or drilled wood blocks. Due to their efficient pollination abilities and ease of management, these bees have become increasingly popular as an alternative to honey bees in agriculture and horticulture. Mason bees are so-called for their habit of using mud to construct their nests, and for their habit of nesting in cracks and crevices of crumbling mortar in walls.
