|Formica rubida, now Manica rubida|
(Species Checklist, Species by Country)
|Based on Ward et al., 2014|
Four of the six species in this genus are found in western North America. One species is endemic to Japan and the other is Palearctic. Colonies are small and nests are usually found in openings in coniferous forests, commonly under stones or with open craters.

Nearly monomorphic ants; total length of workers around 5 - 8 mm. Similar to Myrmica, but differing as follows: Antennal funiculus with a 5-segmented club; propodeum without spines, armed instead with blunt tubercles. Promesonotal suture weak but distinct dorsally. Metanotal groove strongly impressed. Masticatory margins of mandibles each with two large teeth and 12 - 14 following denticles. Palpal formula 6:4. Body wholly yellowish brown, reddish brown, black, or with the head and gaster black and the mesosoma brown. Larvae without anchor-tipped hairs. Pupae are yellow.

Distribution and Richness based on AntMaps
Little has been published on the biology of species within this genus. Food habits, foraging ecology and other aspects of their ecology are poorly known. Probably a generalized scavenger and predator.
Wheeler and Wheeler (1986) report the following about the free living western North American Manica species (Manica invidia, Manica hunteri and Manica bradleyi: The basic nest structure is probably the same for all three species: a reticulum of chambers and galleries connected with chambers under stones and opening to the surface by holes in the bottom of one or more small craters constructed of excavated soil; but great plasticity is manifest in the variations on the basic plan. The nests are usually polycalic and their limits almost impossible to determine. The nature of their food is an unsolved mystery. Workers take insects into the nest; but, in M. bradleyi and hunter only a few workers are out at anyone time, for only a few hours during the day and rarely at night; surely they cannot support a flourishing colony.
Our latest hypothesis is that Manica feeds on ants of other genera. Our tenuous evidence consists of three bits: (1) In Montana we found a Formica fusca mound which contained in one half Formica and in the other half Manica hunteri. (2) In Wyoming we found a F. fusca mound which was occupied only by M. hunteri. (3) Their intrageneric tolerance contrasted with their hostility toward other genera. If this hypothesis is correct, raiding must be an underground affair, for we have never witnessed any raids on the surface.
The ants of this genus are not aggressive, but when their nest is disturbed the workers sting promptly and effectively. The effect of the sting has been reported to be very painful, but we have found it only moderately so. The genus is unusual in that workers show no hostility to workers of another colony of the same species or even of a different species of the same genus; but they are murderously hostile toward workers of other genera.
The gait of the workers is characteristic: steady, deliberate and unhurried but never sluggish.
