Green-head ant
The green-head ant (Rhytidoponera metallica), often simply referred to as the green ant, or sometimes the green-headed ant or in Queensland, the metallic pony ant, is a metallic-green coloured ant, generally 5–7 millimetres (0.20–0.28 in) in length, that can be found throughout Australia, particularly in urban and suburban areas. It is often confused - verbally, not visually - with the weaver ant of northern Queensland, Australia, where it is also referred to as the green ant.Green-head queens are semi-claustral, and forage for food themselves during the early stages of a colony. Queens are difficult to distinguish from workers, they generally have the same build, but are slightly larger with a more pronounced thorax and gaster. Workers forage alone and are omnivorous, however a majority of their diet consists of other insects. Colonies can range from small colonies, to large ones that can be around a metre deep into the ground and contain around a hundred workers.
