On average, the largest member of the Formica pallidefulva species group, Formica dolosa is a wary, fast-running orange ant found in dry, infertile habitats, like pine barrens, dry grasslands and prairies, ridgetops, and other similar habitats with acidic, poor soils. In wetter habitats, it is often replaced by other members of the pallidefulva species group (Trager, 2007).


This species may occasionally be a host of Formica pergandei (Trager, 2007). In New England and the upper Midwest, and also in the Southeast, it is the host species of two newly-described, allopatric Polyergus species. Any Polyergus found with dolosa in Maryland should be intensely scrutinized, as they would constitute a range extension for one of the two species.

There are 7 records in the project database.
