A recent study reports the alarming discovery of red imported fire ants, among the world’s most invasive species, in Europe for the first time. These aggressive ants, scientifically known as Solenopsis invicta, originate from South America and are notorious for their painful stings, large colony sizes, and harm to crops and ecosystems. They are characterized by reddish-brown to reddish-black coloration with a coppery head and measure between 1/8 to 1/4 inch (3-6 mm) in length. Red fire ant colonies are highly organized, polygynous, and can house thousands to hundreds of thousands of ants with multiple queens.
