Rare
Under 5% of wildlife watchers report a Giant Blue Robber Fly sighting in Sydney on a given day, based on 25 verified sightings from GBIF citizen-science data. It is the 279th most-seen of the 742 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.
December
In that month about 10% of wildlife watchers report a Giant Blue Robber Fly in Sydney on a given day, against under 5% in January to November, the lowest months.
Only Sydney, in our data
Sydney is the only city on Wallace's Line with enough records to rate Giant Blue Robber Fly sightings: under 5% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Giant Blue Robber Fly is recorded against all the insects logged in Sydney (25 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.
