Ants are normally listed by their scientific names, this is simply a combination of their ‘genus‘ and ‘species‘ names. For example the scientific name of a carpenter ant is ‘Camponotus pennsylvanicus‘. In this case, Camponotus is the genus (all carpenter ants are in this genus) and pennsylvanicus is the species. When a scientific name has ‘sp.’ after the genus, ie. Camponotus sp. This means all ant species under the genus Camponotus. Sometimes the authors name, who originally described this species, is placed after the ant name, ie. ‘DeGeer’.
