Cavity-nesting bees, also referred to as mason bees, are solitary bees that nest in holes in wood, walls and even hollow plant stems. They use mud and other masonry materials to build dividing walls (‘cells’) that isolate each laid egg in the nest.
Cavity nesters can often be distinguished from other solitary bee species by their robust heads and impressive jaws, which they put to use when constructing each cell.
