In order to maintain populations of organisms, be they plant or animal, it is necessary to have an understanding of their requirements. In this work, the authors have compiled all that is known for southern Africa of the biology of wasps and bees, important pollinators and predators, and have shown how agricultural land use and coastal development impact on the diversity of wasps and bees. The principal focus is the semi-arid to arid areas – the authors’ main study areas over the past 40 years. The work is intended for all who are interested in natural history, conservation and farming, and as a starting point for further observations and research.
