Cerapachys biroi

Cerapachys biroi, or the clonal raider ant, is a queenless clonal ant in the Ooceraea group of the genus Cerapachys. Native to the Asian mainland, this species has become invasive on tropical and subtropical islands throughout the world. Unlike most ants, which have reproductive queens and mostly non-reproductive workers, all individuals in a C. biroi colony reproduce clonally via thelytokous parthenogenesis. Like most cerapachyines, C. biroi are obligate myrmecophages and raid nests of other ant species to feed on the brood.
