Which of the following ants has 1 node?

The answer indicates that all of the listed ants—Pharaoh Ant, Pavement Ant, and Field Ant—have one node, which is a critical feature for identifying these species.

In entomology, ants are typically categorized based on their structural features, including the presence of nodes. A node is a small, bulbous structure located between the thorax and abdomen of ants, and its presence or absence helps in distinguishing different ant species. Some ants have one node, while others may have two or more nodes.

The Pharaoh Ant, often recognized by its small size and light yellow coloration, has one node, which aids in its identification. Similarly, the Pavement Ant, characterized by its dark coloration and distinctive patterns on its body, also features one node. Field Ants come in various sizes and shapes, but many common species generally have one node as well.

Acknowledging that all these ant species share the characteristic of having one node underlines the importance of these anatomical features in taxonomic classification and pest management practices. Understanding these distinctions is crucial for effective identification and control strategies in pest management.
