Myrmecia brevinoda is a species of bull ant native to Australia. These ants are only found in the eastern Australian states of Queensland (only in the eastern areas), New South Wales, Victoria, and the Australian Capital Territory. It was first described in 1910.
Worker ants have been known to measure 3.7 cm (1.5 in) in total length, while queens can exceed 4.0 cm (1.6 in) in length, making them one of the largest types of bull ants in Australia and in the world. Most of their bodies are dark red, with the exception of the bulbous parts of their abdomens being black. Wikipedia →

GBIF citizen-science records
It is estimated from how often the Giant Bulldog Ant is recorded against all the insects logged in Royal National Park (31 verified sightings from 2019 to 2026), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
