Aphaenogaster rudis
Winnow Ant
Aphaenogaster rudis is a common woodland ant in eastern North American hardwood forests, known for its distinctive seed dispersal behavior and frequent colony relocations. Colonies are moderate in size and nest in soil under stones or logs. The species exhibits tool use through debris dropping during foraging, a specialized task performed by subsets of workers. A. rudis is an ecologically dominant forest ant with generalized seasonal activity and no strong food preferences, allowing it to maintain broad temporal and spatial niches in sympatry with other ant species.
