Which ant species is identified by lines on its head?

The pavement ant is characterized by distinct lines or grooves on its head, which is an important identifying feature. These lines create a striated appearance that sets it apart from other ant species. In addition to the lines, pavement ants are typically small, with a dark brown to black coloration and have a pair of spines on their thorax. This striation is a reliable indicator that helps pest control professionals and enthusiasts accurately identify the species, facilitating targeted pest management strategies.

Other ant species mentioned in the choices do not have prominent lines on their heads for identification. For example, fire ants are recognized by their reddish color and aggressive behavior, while carpenter ants are larger and often have a smooth appearance without head striations. Leafcutter ants are known for their unique habit of cutting leaves and have a different physical structure. Understanding these distinctions assists in effective pest control measures and informs proper identification practices.
