From 20 to 1300m although big, populous nests are found at the higher altitudes, usually under stones. The few nests located in the drier coast seemed to be in a miserable and suffering state, with a small number of workers. But for a smaller size the morphology of lowland populations was indistinguishable from other populations. (Espadaler 2007)
