The green-head ant (Rhytidoponera metallica), also known as the green ant or metallic pony ant, is a species of ant that is endemic to Australia. It was described by British entomologist Frederick Smith in 1858 as a member of the genus Rhytidoponera in the subfamily Ectatomminae. These ants measure between 5 to 7 mm (0.20 to 0.28 in). The queens and workers look similar, differing only in size, with the males being the smallest. They are well known for their distinctive metallic appearance, which varies from green to purple or even reddish-violet. Among the most widespread of all insects in Australia, green-head ants are found in almost every Australian state, but are absent in Tasmania. They have also been introduced in New Zealand, where several populations have been established.

  • The green-head ant (Rhytidoponera metallica), also known as the green ant or metallic pony ant, is a species of ant that is endemic to Australia. It was described by British entomologist Frederick Smith in 1858 as a member of the genus Rhytidoponera in the subfamily Ectatomminae. These ants measure between 5 to 7 mm (0.20 to 0.28 in). The queens and workers look similar, differing only in size, with the males being the smallest. They are well known for their distinctive metallic appearance, which varies from green to purple or even reddish-violet. Among the most widespread of all insects in Australia, green-head ants are found in almost every Australian state, but are absent in Tasmania. They have also been introduced in New Zealand, where several populations have been established. This species lives in many habitats, including deserts, forests, woodland and urban areas. They nest underground below logs, stones, twigs, and shrubs, or in decayed wooden stumps, and are sometimes found living in termite mounds. They are among the first insects to be found in burnt-off areas after the embers have stopped smouldering. Rain presents no threat to colonies as long as it is a light shower in continuous sunshine. The green-head ant is diurnal, active throughout the day, preying on arthropods and small insects or collecting sweet substances such as honeydew from sap-sucking insects. They play an important role in seed dispersal, scattering and consuming seeds from a variety of species. Predators include the short-beaked echidna (Tachyglossus aculeatus) and a number of bird species. Green-head ant workers are gamergates, meaning they can reproduce with winged males. With workers taking over the reproductive role, queens are relatively insignificant and are rarely produced in colonies. Nuptial flight begins in spring, with males mating with one or two females. Queens that establish their own colonies are semi-claustral, going out and foraging to support their young. Another way colonies are formed is through budding, where a subset of the colony leaves the main colony for an alternative nest site. The green-head ant is known for its painful and venomous sting that can cause anaphylactic shock in sensitive humans. However, they can also be beneficial to humans, acting as a form of pest control by preying on agricultural pests such as beetles, moths and termites. (en)

Elles sont bien connues pour leur aspect métallique, qui varie du vert au violet ou même au violet rougeâtre. (fr)

  • Зеленоголо́вый мураве́й (лат. Rhytidoponera metallica) — вид мелких тропических муравьёв рода Rhytidoponera из подсемейства Ectatomminae. Несмотря на свой размер (длина тела от 5 до 7 мм), они обладают сильным жалом, яд которого способен вызвать у человека анафилактический шок. Название насекомого связано с необычной металлически блестящей сине-зелёной окраской с переливами от зеленоватой до бронзово-фиолетовой, сходной с таковой у ос-блестянок. Могут служить орудием биологической борьбы с вредителями, убивая сельскохозяйственных вредителей. Эндемик Австралии, интродуцированный в Новую Зеландию. Муравейники строят в почве и под камнями во многих биотопах, включая леса, редколесья, пустыни, открытые луга, а также лужайки и сады в городах. Дневные хищники, которые активны в светлое время суток. Охотятся на насекомых и других членистоногих, собирают падаль и сладкие выделения тлей и червецов. Играют важную роль в распространении семян (мирмекохория) и в уничтожении вредителей (жуков, термитов, гусениц). Рабочие зеленоголового муравья являются гамэргатами и могут спариваться с самцами, настоящие муравьиные матки редки. Брачный лёт происходит весной, основание новых семей — или почкованием, или полунезависимое: самки самостоятельно образуют новую семью, но могут выходить на фуражировку. (ru)
