What is a notable characteristic of Argentine Ants?

Argentine ants are notably characterized by their diet, which primarily consists of sweet substances, such as honeydew produced by aphids, and they also consume proteins when available. This feeding behavior facilitates their rapid population growth and adaptability in various environments. Their preference for sweets is a significant aspect of their ecology, helping them establish and maintain colonies in diverse habitats.

Regarding the other options, Argentine ants can be found in a range of climates, not just limited to winter environments, and they are known for their ability to survive in multiple habitats, including urban areas. They do not exclusively nest indoors nor are they limited to deep soils; they can also form nests outdoors in various environments, from soil to leaf litter. Their adaptability in nesting and feeding contributes to their success as an invasive species in many regions.
