NATIVE BEES

Share

Australia's bees are predominantly solitary, each female building one or more nests in which to rear her offspring without the aid of ‘workers’. Many burrow in the ground though a few bore in dead, rotting wood or pithy stems. Most others are ‘lodgers’, utilizing existing hollows such as borer holes in dead wood, hollow stems and abandoned burrows of other bees and wasps. Lodger bees will also utilize man-made cavities such as nail and bolt holes, pipes and cut bamboo. A few species build free-standing nests on stems or rocks. A variety of materials may be used in nest construction including soil, plant fibre, leaf pieces, leaf pulp, resin and secretions such as wax and silk. Typically, each brood cell is an urn-shaped cavity providing a protective environment for the development of a single individual; it is stocked with sufficient food to enable development from egg to adult and is sealed once it receives an egg.
