Brachyponera chinensis, or the Asian needle ant, is a ponerine ant native to areas of Japan and Asia.[1] The species can also be found in the United States,[2] where it is an adventive and possibly invasive species. It is documented from Georgia, North Carolina, South Carolina, and Virginia, though unpublished records place it in Alabama and Tennessee.[3] Sightings have been confirmed as far north as Maryland.[4] The pest species is of growing concern due to ecological impacts on biodiversity[5] and medical risks to human health, via sting-induced anaphylaxis.[1] It prefers nesting in dark, damp areas in soil beneath stones, logs, stumps, and debris.[3]

The Asian needle ant and the Argentine ant (Linepithema humile) have been battling for territory in the U.S.[6]
