Carpenter ant (Camponotus sp.)The Formicinae are a subfamily within the Formicidae containing ants of moderate evolutionary development.. Formicines retain some primitive features, such as the presence of cocoons around pupae, the presence of ocelli in workers, and little tendency toward reduction of palp or antennal segmentation in most species, except subterranean groups.
Formica is the type genus of the Formicidae, and of the subfamily Formicinae. [3] The type species of genus Formica is the European red wood ant Formica rufa. [1] Ants of this genus tend to be between 4 and 8 mm long. [4] Ants belonging to the Formica genus possess a single knob or bump located between their thorax and abdomen. These ants ...
Ants (family Formicidae in the order Hymenoptera) are the most species-rich of all social insects, with more than 12,000 described species and many others awaiting description. [1] Formicidae is divided into 21 subfamilies , of which 17 contain extant taxa , while four are exclusively fossil . [ 2 ]
Ants are eusocial insects of the family Formicidae and, along with the related wasps and bees, belong to the order Hymenoptera. Ants evolved from vespoid wasp ancestors in the Cretaceous period. More than 13,800 of an estimated total of 22,000 species have been classified.
Brachymyrmex is a genus in the ants subfamily Formicinae. [2] The genus can be recognized by the combination of having nine antennal segments (fewer than most ants) and the petiole concealed by the gaster in dorsal view. They are sometimes called "rover ants". [3] [4]

Polyrhachis is a genus of formicine ants found in the Old World with over 600 species. [2] The genus is yet to be comprehensively resolved and contains many varied species including nest-weavers (e.g. Polyrhachis dives), swimming workers (e.g. Polyrhachis sokolova), soil (e.g. Polyrhachis proxima) and tree-dwellers (e.g. Polyrhachis bicolor).
The longhorn crazy ant is able to invade new habitats and outcompete other species of ants. In 1991, in the large closed dome of the research station Biosphere 2 in the Arizona Desert, no particular ant species was dominant. By 1996, the longhorn crazy ant had virtually replaced all the other ant species.
