Formica dolosa
Wily Field Ant
Formica dolosa is a species of field ant in the genus Formica, family Formicidae. Described by Buren in 1944, this species is part of a large and taxonomically complex genus containing numerous social parasites and free-living species. Like many Formica species, it is likely a generalist in its ecological habits, though specific details of its biology remain limited in the available literature. The species epithet "dolosa" (meaning "wily" or "deceitful") reflects its perceived behavioral characteristics.
Formica francoeuri
Francoeur's Field Ant
Formica francoeuri is a species of field ant in the genus Formica, family Formicidae. It was described by Bolton in 1995. The species is part of the diverse Formica genus, which includes many North American ant species with varied ecological strategies including social parasitism. As a member of the Formicinae subfamily, it lacks a stinger and instead uses formic acid for defense.
Formica pallidefulva
field ant
Formica pallidefulva is a medium-sized field ant native to North America, ranging from reddish-gold in the southern United States to dark brown-black in Canada. Workers measure approximately 5–6 mm and are notably glossy compared to related species. The species excavates underground nests with horizontal and vertical galleries, typically without surface mounds. It serves as a primary host for multiple slave-making ants, including Polyergus lucidus and Formica pergandei, which raid its colonies for brood. Colonies are monogyne, diurnal, and forage solitarily while recruiting nestmates to larger food sources.
