Camponotus festinatus is a large, yellowish brown, non-aggressive ant that is rarely seen during the day [Wheeler, 1910: 314]. It is found in Arizona, Texas, northern Mexico, and parts of New Mexico, and is distinguished by erect hairs on its antennal scapes [Mackay & Mackay, 2002:290]. Identifying specimens of this species is difficult because C. festinatus strongly resembles other southwestern ant species such as C. fragilis and C. vafer [Snelling, 2006:85]. C. festinatus colonies may possess either a single queen or multiple queens spread across several nests [Goodisman & Hahn, 2005: 2185-2197]. Colonies typically contain a few hundred ants, including major and minor worker castes [Wheeler, 1910: 312-314].
