Argentine Ant

Fascinating facts about the Argentine Ant

• One trillion ants march from San Diego up past San Francisco. Researchers estimate the Very Large Colony may have a population of one trillion individuals as of 2010, dwarfing any other insect aggregation on Earth. This sheer mass lets the ants overwhelm native species, monopolize food, and reshape entire ecosystems, showing how a single invasive supercolony can rival human populations in scale.
• At the front line between two rival supercolonies, thirty million ants die each year, a battlefield stretching for miles. The border of the Very Large Colony and the Lake Hodges Colony sees constant, ceaseless fighting, unlike the brief raids of other ants. This relentless war creates massive dead-ant piles.
• Argentine ants survive from, -5 °C up to 45 °C, but they cannot thrive where the mean daily temperature falls below 7-14 °C. This thermal ceiling limits their spread to Mediterranean-type climates, yet within those zones they dominate, illustrating how a narrow temperature niche can still support a global invasion when human activity transports them to suitable habitats.
• In introduced colonies, there may be one queen for every 125 workers, and each queen can lay 20-30 eggs daily, sometimes up to 50-60. With hundreds of queens per nest, the colony can produce a constant stream of brood, fueling rapid expansion and making control difficult.
