SeasonalityMay through to September.IdentificationWorkers range in length from ~2.0-3.0 mm and are a dark golden brown colour. Eyes are large, mandibles have unequal penultimate and ultimate basal teeth, with a constant distance between them on both mandibles, clypeus is a parabolic curve shape, and the scape lacks erect or suberect hairs (Creighton, 1950, and Wheeler and Wheeler, 1963).

Life History
Queens found colonies independently(Fisher and Cover, 2007). Eggs take 23-48 days to hatch, larvae develop and pupate between 16-39 days and pupa hatch in 20-40 days (Tanquary, 1913). Colonies are made up of…

Conservation
Not of concern.
Diet Info
Feed predominantly on aphids and plant secretions, but will take dead insects (Creighton, 1950, and Wheeler and Wheeler, 1963).
Range
Middle North America, not extending far north into the boreal forest, but also not extending far into the dry south (Wheeler and Wheeler, 1963). In Alberta commonly found in the foothills and forested areas (Sharplin, 1966).
