Biology
Ellison et al. (2012) - Little is known about this hard-to-find species. It was originally described from a colony found in a piece of hickory wood in Pennsylvania, and it can be found in trees in old cavities made by long-horned beetles (family Cerambycidae). It is one of only a few arboreal ants in New England; it often forages on the trunks and major limbs of mature oaks, walnuts, and hickories. It has not been observed foraging on the ground.
