the other bees

"Most other bees ... are solitary in the sense that every female is fertile, and typically inhabits a nest she constructs herself. There are no worker bees for these species. Solitary bees typically produce neither honey nor beeswax ... Solitary bees create nests in hollow reeds or twigs, holes in wood, or, most commonly, in tunnels in the ground... While solitary females each make individual nests, some species are gregarious, preferring to make nests near others of the same species, giving the appearance to the casual observer that they are social."
