Identification

This is a large, attractive, red and black species. The majors, minors and females have a black head and gaster, and a red mesosoma. The punctures on the head are 2 sizes, most are very fine, larger punctures are scattered over the surface of the head. The lateral clypeal angles are present, but are not well developed, the antennal scapes are without erect hairs (except at apex), the scapes extend nearly 1 funicular segment past the posterior lateral corner in both the majors and the females. Erect hairs are sparse on the head, mesosoma, petiole and gaster, and absent on the cheeks, malar area, sides and head, posterior lateral corners, and tibiae, except for 2 rows of hairs on the flexor surface. The pubescence on the gaster is very fine, with none of the hairs overlapping adjacent hairs. (Mackay and Mackay 2002)

Distribution

Southeastern Canada, Nova Scotia and Quebec through northeastern United States and south to New Mexico. In the Atlantic states, it lives by preference in hilly country, usually at higher elevations than pennsylvanicus and ferrugineus.

Biology

The pupae of this medium-sized carpenter ant are often parasitized by small Pseudochalcura gibbosa wasps; the larvae of these wasps are taken back to the nest by the ants as a food source for the developing brood. But the eaten become the eaters, as some of the wasp larvae develop and then devour the ants. (Ellison et al. 2012)

Description

Worker

Wheeler (1910) - Major and minor. Sculpture finer and more superficial than in whymperi and Camponotus pennsylvanicus; so that the whole surface of the body and especially the gaster is smoother and more shining. Hairs and pubescence pale yellow or white, sparse and short; the pubescence on the gaster being nearly as short as in whymperi and decidedly more dilate; the minute hairs on the scapes and legs more appressed. Head, antennae and gaster black; thorax, petiole, and legs red, the tibiae and tarsi often somewhat darker. Posterior edges of gastric segments yellowish. In the worker media and minima, the mandibles and sometimes also the clypeus are red.

Queen

Wheeler (1910) - Resembling the worker major, but the thorax and gaster very smooth and shining; the latter with shorter hairs and very short and dilute pubescence. Dorsal portion of pronotum, scutellum, metanotum and three more or less distinct longitudinal bands on the mesonotum, black. In some specimens, the whole mesonotum and dorsal portion of the epinotum are black. Extreme base of first gastric segment often red or yellow. In other respects, the color is like that of the worker. Wings strongly tinged with yellowish brown; veins and stigma yellow.

Male

Wheeler (1910) - Indistinguishable from the male of pennsylvanicus. Wings somewhat paler than in the female.
