It isn’t often we get a single cicada publication as complete and awesome as Cicadas of southern Africa: An illustrated guide to known species by R.D. Stephen. The document is 224 pages long and includes color photos of dozens of cicadas with maps & text descriptions. This guide covers cicadas from Botswana, Lesotho, Namibia, South Africa, and Zimbabwe.
