Tetramorium

Tetramorium is a genus of often small to medium-sized ants found worldwide, especially in tropical and subtropical regions. They typically have smooth, shiny bodies with distinct nodes on their waist. Many species, like the common pavement ant, are highly adaptable and live in a variety of environments, including urban areas. They are social insects, living in large colonies with a structured hierarchy. Tetramorium ants are known for their importance in ecosystems as predators of other small invertebrates and sometimes as pests when they invade homes or disturb crops.
