Eusocial insect societies are characterised by a clear division of labour between non-breeding workers and breeding queens and queens often do not contribute to foraging, defence and other maintenance tasks. It has been suggested that the structure and organisation of social mole-rat groups resembles that of eusocial insect societies. However, the division of labour has rarely been investigated in wild mole-rats and it is unknown whether breeders show decreased foraging activity compared to non-breeding helpers in natural groups. Here we show that, in wild Damaraland mole-rats (Fukomys damarensis), breeding males and females show lower activity in foraging areas than non-breeding group members. Both breeders and non-breeders displayed variation in activity across the different seasons. Our results suggest that group living allows social mole-rat breeders to reduce their investment in energetically costly and potentially risky foraging tasks which could contribute to the extended life-span of breeding individuals in this species and other social mole-rats.
