Mortar Bee


Mortar bees, also known as Masonry Bees, are sizable, yellow, and light brown bees that are frequently found on their own rather than in a nest. They enjoy digging in cracks and holes in the sand, rock faces, hard soil, and brick foundations, hence the name Mortar Bee.

It is not known that they sting people. Mortar bees, sometimes known as masonry bees, are so named because they occasionally nest in the mortar joints of brick buildings or use wall cracks. The most prevalent kind of bee, known scientifically as Osmia Rufa, is one of several different bee species that perform this function.
