Brachyponera chinensis
Asian needle ant
Brachyponera chinensis, the Asian needle ant, is a ponerine ant native to Japan and mainland Asia that has established invasive populations in the eastern United States since the 1930s. The species exhibits unique pre-adapted traits for invasion success, including tolerance to inbreeding through sib-mating that maintains genetic diversity despite founder effects. It is a termite specialist predator that competes aggressively with native ant species, causing significant biodiversity reductions in invaded areas. The ant poses medical risks to humans through venomous stings that can induce anaphylaxis.
