Formica dakotensis

This ant nests in mounds, often thatched with detritus, or under stones. It enslaves F. fusca, F. lepida, F. montana, F. subsericea and F. pallidefulva. Like most species of Formica, this species tends aphids. (Mackay and Mackay 2002)

Identification
Workers, females (and even males) of this species are easily recognized as the node of the petiole is flat or has a slightly concave apex, as seen from the front or back. The sides of the node are nearly straight and parallel. The palpi are remarkably short. The female is smooth and shining, and smaller than the largest workers.

Distribution
Canada, Alberta. United States, widely distributed.

Distribution based on Regional Taxon Lists
Nearctic Region: Canada, United States.

Habitat
In New Mexico (Mackay and Mackay 2002) - Grasslands up to ponderosa pine forests.

Biology
Temporary hosts for F. dakotensis are, , , and.

Nevada, Wheeler and Wheeler (1986) - Our 8 records are from 7 localities, which are widely scattered north of the Hot Desert. Two are in the Coniferous Forest Biome, 1 in the ectotone above, and 1 in the Alpine Biome. Five nests were under stones and 1 was under a dead sagebrush trunk.
