n African Entomology - Southward expansion in beetle and butterfly ranges in South Africa

Volume 19, Issue 1
  • ISSN : 1021-3589



Comparisons of the historical distribution range of two fruit chafers ( and ), one longhorn beetle () and five butterflies ( and ), with their current ranges show that during the last two decades these species have extended southwards by 0.54-5.64° latitude, along distances of some 90-830 km. Although direct anthropogenic activities (. land-use change, soil and plant transport) are partly responsible for these extensions, it is possible that they are also linked to the 0.5° temperature rise experienced by the region during the same period, as a direct consequence of global warming.
