On 11 April 2013 at 15h00 (ambient temperature 24°C), I observed a large Meroles ctenodactylus (about 20 cm total length) attack and partially consume a large Armoured Darkling Beetle (Gonopus tibialis) (about 2 cm long). This observation was made about 50 km north of Oranjemund (28°05'39.3"S, 16°11'44.3"E, 350 m) in the Sperrgebied National Park, Namibia during a vertebrate fauna survey prior to proposed mining exploration activities. The substrate was sandy and the general area dominated by Brownanthus arenosus and Salsola nollothensis shrubs and tufts of Cladoraphis spinosa grass. can be variable in is variable within its range (pers. obs., Mirko Barts pers.comm.).
