Definition

A hyperdiverse of in the Formicinae, comprising over 1,500 described and representing the most species-rich genus of ants globally. Members range from minute to very large in body size and occupy diverse ; while commonly called ',' only a subset—primarily in the subgenera Camponotus and Myrmentoma—excavate wood for nesting, whereas many species nest in soil, preformed cavities, or arboreal substrates. The genus exhibits considerable morphological and behavioral diversity, including polymorphic and, in some species, obligate associations with trophobiotic or specialized plant mutualisms.

Usage Notes

The '' properly applies only to wood-nesting Camponotus and should not be used for the entire ; many Camponotus species are ground-nesting or arboreal and cause no structural damage. The genus is frequently split into numerous subgenera (e.g., Tanaemyrmex, Myrmamblys, Myrmentoma) based on and nesting , though subgeneric classification remains unstable. Species identification often requires examination of minor morphological characters such as pilosity patterns, propodeal shape, and petiolar node profile. Camponotus is sometimes confused with Colobopsis, a related genus of specialized cavity-dwelling formerly treated as a subgenus of Camponotus.
