Remarks: This species is known to be widely distributed all over the world, having been spread intentionally by man or unintentionally by passive transport or natural dispersal into acceptable biotopes. It has been commonly recorded in agricultural fields ( Fragoso et al. 1999). In South Africa, it was reported from seven provinces: LP, MP, KZN, EC, WC, GP, NW ( NMSAD). It occurs in most habitats (Plisko 2001, 2010), and Ljungström (1972 a) noted large populations in coastal sugarcane plantations.
