Found in mostly grassland habitats but also urban lawns and cultivated fields.
Found through May to September.
Workers are ~3.5-6.5 mm in length and are a black, with reddish undertones, which can be seen most easily in the appendages. Their gulae lack erect hairs, the hairs on the first tergite of the abdomen are numerous and pubescence on the abdomen creates a shiny silvery luster (Wheeler and Wheeler, 1977).
Colonies of this species commonly have up to three queens and consist of thousands sometimes tens of thousands of workers. (Snyder, 1993).
Not of concern.
Omnivorous but are also above ground aphid farmers (Wheeler and Wheeler, 1977).
Found most commonly in the western half of North America but found as far east as Massachusetts (Wheeler and Wheeler, 1977). In Alberta it is most commonly found in the central and southern regions.
These ants are similar in form to both Formica fusca and Formica subsericea when looking at with the naked eye.
