Rare
Under 5% of wildlife watchers report a Square-Headed Masked Bee sighting in Melbourne on a given day, based on 28 verified sightings from GBIF citizen-science data. It is the 377th 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 20%, if each day is a fresh chance.
November and December
In those months about 10% of wildlife watchers report a Square-Headed Masked Bee in Melbourne on a given day, against under 5% in January to October, the lowest months.
Only Melbourne, in our data
Melbourne is the only city on Wallace's Line with enough records to rate Square-Headed Masked Bee sightings: under 5% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Square-Headed Masked Bee is recorded against all the insects logged in Melbourne (28 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.
