The food relocation and nesting behavior of the South American genus Eucranium Brullé is described based on observations carried out under natural conditions. Food preference, food transportation, period of surface activity, and habitat preference are described for two species, E. arachnoides Brullé and E. planicolle Burmeister. The biology and food relocation behavior of Eucranium is compared with that of the morphologically similar South African subgenus Scarabaeus (Pachysoma) MacLeay. The convergent adaptations to psamophilous habitats of Eucranium and S. (Pachysoma) are discussed.
