[4] Nest entrances are generally funnel-shaped with diameters up to 4 cm, which resulted in the common name funnel ants.

These nests can be a serious problem for golfers or on pastures and unsealed airstrips, because the fragile surface easily collapses under pressure.

[3] Where it occurs, Aphaenogaster bioturbation is an important soil and landscape process.

[4] Aphaenogaster ants probably get most of their food from tended aphids on the roots of plants, which explains that they are rarely seen on the surface.

The funnel-shaped openings could play a role in trapping arthropods, which are also eaten.
