On the basis of ecological data, breeding experiments, and activity trials, the two species of red spiders (Anychus orientalis, Zacher and Epitetranychus althaeae, Hanst.) found in Palestine are differentiated. The reason for the different distribution of the two species throughout the world is explained. The common red species is found to be a cosmopolitan, the Oriental red spider a subtropical element.
