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 →

Likely
About 40% of wildlife watchers report a Red Bull Ant sighting in Booderee National Park on a given day, based on 46 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 2nd most-seen of the 59 insects we can rate there. Over three days the chance rises to about 80%, and over a week to over 90%, if each day is a fresh chance.
August to April
In those months about 40% of wildlife watchers report a Red Bull Ant in Booderee National Park on a given day, against under 5% in June, the lowest month.
Between 10 am and 1 pm
Across all the parks we cover, that three-hour window holds the most Red Bull Ant sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Yes
Of the 3 parks where we can rate Red Bull Ant sightings, Booderee National Park has the highest daily chance: about 40%. Next come Royal National Park (Australia, about 40%) and Blue Mountains National Park (Australia, about 10%).
GBIF citizen-science records
It is estimated from how often the Red Bull Ant is recorded against all the insects logged in Booderee National Park (46 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.
