Carpenter ant standard size of carpenter ant colonies elsewhere. When workers find food sources, they communicate this information to the rest of the nest. They use biochemical pheromones to mark the shortest path that can be taken from the nest to the source. When a sizable number of workers follows this trail, the strength of the cue increases and a foraging trail is established. This ends when the food source is depleted. The workers will then feed the queen and the larvae by consuming the food they have found, and regurgitating the food at the nest. Foraging trails can either be under
Meat ant chambers where the population remains during the winter. In the upper areas of the colony, the galleries and shafts only account for 7–10% of nest space. For example, the galleries of excavated colonies occupy whereas the total volume is around . Overall, a nest may dwell extremely deep beneath the soil as excavated nests are as deep as . A diurnal species (active mainly during the day), the meat ant shows minimal interaction with nocturnal ant species when their territories overlap. The meat ant and other members of the "I. purpureus" species group are regarded as a dominant group of
