Angola Plateau Yields Blue-Glowing Spiders & New Species

An expedition in eastern Angola's remote Lisima plateau has discovered dozens of species potentially unknown to science. This region, a "biodiversity blank spot," harbors unique life, including a crab spider that emits a blue glow under ultraviolet light and a ladybird orb-web spider mimicking toxic insects for protection. The Cassai Life Atlas survey, conducted in February by The Wilderness Project, documented numerous new insects like dragonflies, moths, and grasshoppers.

Notable existing species found include the gaboon adder with exceptionally long fangs and a flightless bat fly. Expedition leader Rob Taylor described the fieldwork as challenging due to the rainy season but productive, with scientists surveying wetlands and forests when logistics caused delays. The findings underscore the importance of conservation efforts.

The Lisima plateau, vital for several major river systems, is facing threats from potential habitat loss due to agriculture and mining impacting freshwater quality. The Wilderness Project is advocating for formal protection of the area, which was recognized as a wetland of international importance by Ramsar in October, to ensure the long-term survival of its unique biodiversity.
