Nests in open woods and sunny meadows (Wheeler and Wheeler, 1973). In Alberta this ant is found aspen parkland forests (Sharplin, 1966).

Workers are ~4.0-7.0 mm in length, have a yellowish-red head and thorax with a brown gaster that darkens posteriorly (Wheeler and Wheeler, 1963). The dorsum is entirely lacking erect hairs, has a board head and the petiolar scale ends in a blunt crest. The clypeus also has a median notch, the declivous face of the epinotum descends at a right angle (Wheeler and Wheeler, 1963).
A facultative slave making ant of numerous fusca group Formica species but will also nest without slaves (Wheeler and Wheeler, 1963). Queens once mated after their nuptial flights in late July early August raid host ant species nests, killing the workers and queen, and appropriating the brood for herself (Wheeler and Wheeler, 1963). Raiding columns are usually started in mid-afternoon and will complete destroy the host species colony (Wheeler and Wheeler, 1963).
Not of concern.
Omnivorous, but are common insect predators, will also tend aphids (Wheeler and Wheeler, 1963).
