Arctosa cinerea


The giant riverbank, or sand wolf spider (Arctosa cinerea) is one of Europe’s largest wolf spiders with a body length in males of 12–14 mm and in females 14–17 mm. Its highly contrasting light and dark (grey-brown or yellow-grey) markings make these ground-living animals almost impossible to detect when they remain still on a sand or gravel substrate (Bellmann 1997).
