Biology:

Habitat: A. rudis is locally common to very abundant in thickets, remnant and mature second-growth, mesic woodlands and forest. It also nests in prairie oak groves and occasionally extends into prairie areas where populations of this ant abound in adjacent woodland. A. rudis may occur in large urban parks, campuses and cemeteries with groves of shrubs or. It nests in soil, in the root-zone of bunch-forming sedges and grasses, beneath rocks and in decomposed wood, even in old cans and other trash discarded in the woods. It commonly nests inside wood fallen wood that is in the mid to latter stages of decomposition and in the duff between large vines and the base of supporting trees.

Natural History: See account for A. fulva -- I am unable to say any thing that clearly distinguishes this ant from A. fulva behaviorally, but ecologically, it may be more restricted to mesic sites.
