Myrmecia swalei is an Australian ant which belongs to the genus Myrmecia. This species is native to Australia and is commonly distributed in Western Australia and South Australia. It was described by Crawley in 1922. Mandibles between the workers and queen are notable. The workers have larger mandibles while the queens are smaller. The average length for a worker is around 11–12.5 millimetres, and the queen is larger at 15–16.5 millimetres. The head, postpetiole and gaster are black, thorax and node is a bright red colour, and the mandibles are yellow. The antennae and legs are brown, but the scapes are more of a darker brown compared to the antennae and legs. Wikipedia →

Rare
Under 5% of wildlife watchers report a Myrmecia swalei sighting in Perth on a given day, based on 10 verified sightings from GBIF citizen-science data. It is the 165th most-seen of the 275 insects we can rate there. Over three days the chance rises to about 10%, and over a week to about 30%, if each day is a fresh chance.
January–March and July
In those months about 10% of wildlife watchers report a Myrmecia swalei in Perth on a given day, against under 5% in April–June and August–December, the lowest months.
Only Perth, in our data
Perth is the only city on Wallace's Line with enough records to rate Myrmecia swalei sightings: under 5% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Myrmecia swalei is recorded against all the insects logged in Perth (10 verified sightings), 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.
