What is a distinguishing feature of Argentine ants?

Argentine ants possess a notable characteristic in that they form multiple colonies, which can often contain numerous queens. This trait allows them to spread and adapt more easily within their environment. The presence of multiple queens in different colonies leads to a unique social structure that enhances their ability to proliferate and establish dominance in new areas.

While the option concerning them not stinging or biting is true, it does not serve to define Argentine ants distinctly when compared to their multi-colony existence. Unlike some other ant species that have a hierarchical colony structure with a single queen, the Argentine ant's ability to operate with multiple queens across colonies illustrates their adaptability and resilience, making option A a more defining feature of these ants.
