In British Columbia, nuptial flights occur from mid-August to mid-September. Colonies are presumably founded monogynously, and dealate queens are semi-claustral, (meaning they need to forage for food throughout the founding stages). Dealate queens often overwinter before beginning the egg laying process.
According to Miles Maxcer from Montana State University, this species interest in food sources changes rapidly. Workers forage alone.
The following information is derived from Barry Bolton's New General Catalogue, a catalogue of the world's ants.

(Cole selected hunteri as the senior name for this species using the Principle of the First Reviser.)
Worker: Length 4-6 mm.
Body and appendages brownish red or ferruginous, with a large, black, subtriangular spot on the vertex and a band of the same color across the posterior portion of the first gastric segment. Frontal area, posterior clypeal suture, antennal clubs and dental border of mandibles more or less infuscated. Upper surface of head with coarse, scattered punctures in addition to the rugae. Smooth areas on the head, thorax and pedicel. Hairs pale yellow. Anterior clypeal border entire. Base of propodeum somewhat flattened, anteroventral protuberance of postpetiole broadly rounded.
Described from a dozen specimens taken by Dr. S.J. Hunter from a couple of nests on the slopes of two mountains on the Madison River, nearly opposite the mouth of Beaver Creek, Montana, at an altitude of about 7,500 feet. The nests were in shaley earth and apparently of the crater type.
