Formica (genus of ants)

Formica is a genus of ants commonly known as wood ants or fire ants, depending on the species. They are social insects that live in large colonies, often in or around soil, wood, or leaf litter. Formica ants play important roles in ecosystems by controlling pest populations and aiding in decomposition. They are characterized by their smooth, shiny bodies and can vary in size and color. They communicate and coordinate through chemical signals called pheromones. Some species are known for their aggressive behavior when defending their nests. Overall, Formica ants are vital components of many terrestrial habitats.
