How many nodes does a carpenter ant possess?

Carpenter ants possess one node, which is a distinct characteristic that differentiates them from other ant species. The structure of an ant's thorax is a key factor in identification. In the case of carpenter ants, their thorax appears smooth and evenly rounded when viewed from the side, indicating the presence of only that single node.

This anatomical feature is part of what defines carpenter ants within the larger family of Formicidae, as other ant species may have two nodes or entirely different thoracic structures. Understanding these morphological distinctions is crucial for proper identification and effective pest management, particularly in contexts like termite inspections where accurate identification of ant species can influence control measures.

Recognizing that carpenter ants have one node helps entomologists and pest control operators differentiate them from other ants which may share similar characteristics but have different node configurations.
