A aphodiine dung beetle allows itself to be carried back to an Acromyrmex crassispinus nest. The biology of these beetles has not been studied, but it is possible that they breed in the ant's midden chambers.

Acromyrmex crassispinus carrying a live aphodiine dung beetle, for reasons we can only guess. It is possible, for example, that the beetles breed in the ant's midden chambers, helping the ants to process waste, and the adults are attractive to the ants as a way of locating a suitable nest.
