The month of May brings colonies of Chimney Bees ( Diadasia bituberculata ) to my favorite trail. While it seems risky to be down among them like this, I’ve never been stung. They live in nesting aggregations.
This means that many individual female bees will build their independent nests close to each other in suitable soil, often in the same patch of ground.
While they nest in close proximity, each female is responsible for building her own nest, provisioning it with pollen and nectar, and laying her own eggs, without cooperative brood care or division of labor among individuals.
