Rare
Under 5% of wildlife watchers report a Black-Scaped Bull Ant sighting in Melbourne on a given day, based on 52 verified sightings from GBIF citizen-science data. It is the 253rd most-seen of the 875 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.
September and November
In those months about 10% of wildlife watchers report a Black-Scaped Bull Ant in Melbourne on a given day, against under 5% in October and December–August, the lowest months.
Between 2 and 5 pm
Across all the parks we cover, that three-hour window holds the most Black-Scaped Bull Ant sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Only Melbourne, in our data
Melbourne is the only city on Wallace's Line with enough records to rate Black-Scaped Bull Ant sightings: under 5% of wildlife watchers there report one on a given day.

GBIF citizen-science records
It is estimated from how often the Black-Scaped Bull Ant is recorded against all the insects logged in Melbourne (52 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.
