According to antweb.org there are over 100 species of Rhytidiponera ants in Australia but the most well known is the Green-headed Ant – Rhytidiponera metallica. These ants have terrorised children across the country, surely for as long as there have been people here, and adults are not immune to their painful stings. But they are more than just another thing in Australia that doesn’t like people – they are vital to some of our ecosystems. Other than invading the beautiful lawn you’ve spent hours and hours caring for, these ants provide a seed distribution service that is vital for the survival of some of our native plants. Ants and plants have been co-evolving very happily for millennia, and I can say something environmentally friendly like “let’s make sure they stay that way” but honestly, after we’re long gone, nature will be there until the end.
