Explanation of Names
Specific name is Latin for "from New York."
Relatively shiny, large carpenter ant worker with distinctly red mesosoma is unique over most of its range. In the western part, where it overlaps with C. vicinus, the unkeeled clypeus and relatively shorter limbs are technical characters to distinguish C. novaeboracensis.
Males are black and difficult to distinguish from related species.
"Color pattern of the mesosoma (apparent thorax), namely the contrast between shining black mesoscutellum and mainly red reminder, is typical for reproductive females of this widespread eastern Carpenter Ant species." -- Richard Vernier
Wet wooded areas, bogs, edges of wetlands.
Colony enters diapause in the winter.
Easily distinguished from its relative Camponotus pennsylvanicus by the red thorax.
