Prior to Trager's 2007 revision of the Formica pallidefulva species group, there was substantial confusion among several species within the group. This species has been lumped with F. dolosa in the past, under the now defunct name F. schaufussi, and older literature records may be confused. Formica incerta, as presently recognized, is primarily a grassland and field species, ranging from New England west to portions of the Great Plains and extending to grasslands east of the Rockies in Colorado. It also ranges down the Appalachians at higher elevations, in meadow habitats and balds. Despite a preference for grassland, this ant can occur in more marginal habitats like lawns and parks (Trager, 2007).


This ant is the host species for the dulotic Polyergus lucidus.

There are 5 records in the project database.
