Formicinae ants are abundant in Kansas, second only to myrmicine ants. Many species feed on the sweet excretions of other insects (such as aphids and scale insects). Colonies can contain several thousand individuals. Members of the genus Formica often build conspicuous mounds. Species within the genera Camponotus and Formica are the most common fomicine ants in Kansas.
