scientific name    Formica impexa    

habitat
In Alberta have only been found along the bank of the Athabasca River.

seasonality
Found through May to September.

identification
Workers are ~3.3-6.0 mm in length and head and thorax are red and the abdomen is black (Wheeler, 1905). The epinotum of this species is very low and the erect hairs on the first gastric tergite are very evenly spaced (Wheeler and Wheeler, 1963). The femora and tibiae of Formica impexa along with the antennal scape lack erect hairs.

life history
Are temporary social parasites of other Formica species (Fisher and Cover, 2007). New mated queens invade host nests, kill the queen and take over the nest as the host workers queen, however, unlike Polyergus or some sanguinea group Formica, they do not raid for slaves, and nests of Formica impexa once mature will have no other ant species in it (Wheeler and Wheeler, 1913 and Fisher and Cover, 2007).

conservation
Not of concern.

diet info
Omnivorous but are also above ground aphid farmers.

range
Ranges across most of western North America, (Wheeler, 1913).
