What You'll Learn
Green-head ants are scavengers and predators
Green-head ants are among the most widespread insects in Australia, found in almost every state. They are also present in New Zealand, with populations established in Napier, Auckland, and Mount Maunganui. These ants are known for their distinctive metallic sheen, varying from green to purple or even reddish-violet. They measure between 5 and 7 mm in size, with queens and workers differing only in size, and males being the smallest.
These ants are adaptable and can be found in various habitats, including deserts, forests, woodlands, and even urban areas. They nest underground below logs, stones, twigs, and shrubs, or in decayed wooden stumps, and sometimes in termite mounds. They are quick foragers and are often one of the first insects to search for food after bushfires, even while the embers are still smouldering. They are also undeterred by light rain as long as it is followed by sunshine.
The diet of green-head ants can be quite diverse, as they are known to eat the Eurycnema goliath eggs, which are collected and carried back to their nests. Additionally, they feed on the honeydew produced by sap-sucking insects and have a preference for seeds with low mechanical defence properties. Experiments have also shown that their diet can impact the mortality rates within colonies, with those fed a standardised artificial diet of digestible carbohydrates and honey-water having lower worker mortality rates.

They eat animal material, insects, arthropods, seeds, honeydew, and nectar
Australian green-head ants are among the most widespread insects in Australia, found in almost every Australian state except Tasmania. They are well-known for their distinctive metallic appearance, varying from green to purple or even reddish-violet. These ants are scavengers, predators, and seed-eaters, and they will eat a broad range of foods, including animal material, insects, arthropods, seeds, honeydew, and nectar.
As scavengers, they feed on animal material, which can include small insects and arthropods, such as beetles, moths, and termites, which they kill with their stingers. They also scavenge for seeds, with a preference for those with low mechanical defence properties, and they collect honeydew, a sweet substance produced by sap-sucking insects.
In addition to their scavenging behaviour, green-head ants are also active hunters. The workers of the colony specifically target beetles, moths, and termites, using their stingers to inject venom and kill their prey. This behaviour is typical of primitive general predators, as they do not exhibit the advanced foraging strategies of other species, such as group hunting and trail pheromone communication.
The broad diet of green-head ants contributes to their success in various habitats, including deserts, forests, woodlands, and even urban areas. They are quick to colonise new areas, particularly after disturbances like bushfires, and are adaptable to different food sources, which likely contributes to their widespread distribution across Australia.
While the green-head ant primarily focuses on the aforementioned food sources, they have been known to exhibit some flexibility in their diet. In experimental settings, green-head ants have been observed to thrive on a variety of diets, including artificial ones consisting of whole raw eggs, honey, vitamin-mineral capsules, honey-water, and Drosophila flies.

They hunt beetles, moths, and termites
Australian green-head ants are scavengers, predators, and seed-eaters. They are known to prey on beetles, moths, and termites, injecting them with venom from their stingers.
The workers of the colony are responsible for hunting and killing these insects. They are distinct from the queen, who is larger, and the male ants, who are the smallest. These ants are well-known for their metallic appearance, which can vary from green to purple or even reddish-violet. They measure between 5 and 7 mm and are found throughout Australia, though they are absent in Tasmania.
Beetles, moths, and termites are just a part of the broad diet of the green-head ant, which also includes other small arthropods, honeydew from sap-sucking insects, and seeds. They are adaptable and will eat whatever food sources are available, which may be why they are able to coexist peacefully with more dominant species, such as meat ants.
One unique aspect of green-head ants is their ability to quickly colonise disturbed areas, which has contributed to their success in urban environments. They are often one of the first insects to forage after bushfires, and they are undeterred by light showers as long as the sun continues to shine. This adaptability may also contribute to their ability to find food sources and survive alongside more dominant ant species.
While green-head ants are predators, they are also preyed upon by various animals, including assassin bugs, the short-beaked echidna, and several species of birds. They are also susceptible to parasites, which have been observed in both workers and larvae. Despite these threats, green-head ants remain one of the most widespread and successful ant species in Australia.

They are eaten by birds, assassin bugs, and the short-beaked echidna
While Australian green-head ants are predators and scavengers with a broad diet, they are also prey for several species. They are eaten by birds, assassin bugs, and the short-beaked echidna.
The green-head ant is found throughout Victoria, New South Wales, the Australian Capital Territory, and South Australia. They are also present in Western Australia, the Northern Territory, and Queensland. These ants are among the most widespread insects in Australia, and their distinctive green to purple sheen makes them easily identifiable. They are scavengers and predators, feeding on animal material, insects, small arthropods, and seeds.
Despite their foraging abilities, green-head ants are preyed upon by several species. Birds such as the Australian white ibis, black kite, masked lapwing, and the Australian owlet-nightjar include these ants in their diet. The short-beaked echidna, or Tachyglossus aculeatus, also preys on green-head ants, as evidenced by the presence of worker ant remains in its faeces.
Additionally, assassin bugs have been known to hunt these ants. Beyond these predators, green-head ants also face threats from parasites. Examinations of worker ants have revealed late-stage pupae of unidentified parasites in their thoraces. Furthermore, myrmecophilous insects, such as the beetle Chlamydopsis longipes, have been observed living within green-head ant colonies.
While green-head ants have a diverse diet and are well-adapted to their environment, they are not exempt from becoming a meal for other creatures in the food chain. This is a testament to the intricate balance of nature, where even predators can become prey.

They are edible and taste like lemon
Australian green ants, also known as green-head ants, are edible and offer a unique culinary experience with their lemon-like flavour. They are commonly found in the Northern Territory and far north Queensland of tropical Australia, inhabiting open woodlands and forests.
These ants, with their distinctive metallic sheen, vary in colour from green to purple or even reddish-violet. They are widespread in Australia, found in almost every state except Tasmania. They are scavengers and predators, feeding on a variety of animal material, insects, small arthropods, and seeds. Their ability to quickly colonise new areas, including disturbed habitats and urban environments, contributes to their abundance.
The edible part of the green ant is its abdomen, which delivers a powerful burst of lemon flavour. While the entire ant can be consumed, it is recommended to avoid eating them alive due to their ability to pinch. The lemon-like taste of these ants makes them an intriguing garnish or flavouring agent, adding a unique twist to dishes.
The Larrakia people, native to Australia, are known for their ethical harvesting of green ants, showcasing their cultural connection to the land and nature. The process of harvesting and preparing these ants for consumption is an art passed down through generations, contributing to the rich culinary heritage of the region.
In addition to their culinary uses, green ants play a significant role in the ecosystem. They are an important food source for various predators, including birds such as the Australian white ibis, black kite, masked lapwing, and the Australian owlet-nightjar. The presence of green ants in the environment contributes to the diversity and balance of the local food web.
