RECOGNITION
Description
Species are most easily identified from the major workers. Many are large ants; all have antennal bases separated from clypeal border by a space at least equal to the maximum diameter of the scape, mesosomal dorsal profile of most a continuous curve from pronotum through propodeum,except some subgenus Colobopsis and one of Myrmentoma. The former are easily recognized by the truncate and heavily punctate circumoral portion of the head of majors.
Body Length
Queens: 9-20 mm; Males: 5-13 mm; Workers are polymorphic, ranging from 4-7 in smaller species, up to 7-13+ in larger species.
Diversity
Nearctica lists 51 species.

BIOLOGY
Food
Omnivorous - eat honeydew, sap, living and dead insects, etc. Do not eat wood, only nest in it, and usually only after fungi have softened it.
Habitat
Forested areas, fewer but also present in deserts, grasslands and boreal forest, some also in urban and suburban areas; may build galleries in wood, or inhabit within-wall spaces in buildings or economically important trees, and are considered pests. Alates of early-flying species are reared in late summer, then overwinter in the nest. This is one of the most species-rich ant genera, with perhaps 1000 species World-wide.
Nesting Preferences
A eusocial insect with a complex life cycle.
Range
Nearly World-wide, except the polar regions.
Diversity
Nearctica lists 51 species.
Active Period
Active during the frost-free season in the north, all year during warm weather in southernmost USA. Species of colder regions enter a deep diapause in winter, characterized by a physiological state that permits them to supercool to temperatures well below freezing without themselves freezing. Mating flights of the majority of species occur late April-May.
