Myrmecia gulosa, the red bull ant, also known as the giant bull ant or Bulldog Ant, is a species of bulldog ant from the genus Myrmecia. It is abundant throughout Eastern Australia.

Being one of the larger ant species, adult individuals have been observed to be as long as 15 mm to 30 mm in body length. The head and thorax are typically coloured red-brown; the rear half of the abdomen is black and the mandibles brown-yellow. Adults characteristically possess the long, powerful serrated mandibles and a venom-laced sting that is capable of causing severe pain for a couple of days. Unlike most other ant species, red bull ants lack the ability of chemical senses; however, this is compensated by their extremely keen vision, with which they can spot and respond to intruders up to two metres away.
Myrmecia gulosa ants are abundant in eastern Australia. They can be found in the coastal regions of Queensland and eastern New South Wales. Populations can be found in the... Wikipedia →

GBIF citizen-science records
It is estimated from how often the Red Bull Ant is recorded against all the insects logged in Royal National Park (116 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.
