Rare
Under 5% of wildlife watchers report a Banks' Brown sighting in Sydney on a given day, based on 5 verified sightings from GBIF citizen-science data. It is the 666th 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.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Banks' Brown in Sydney on a given day, so our monthly data shows no clear season.
Between noon and 3 pm
Across all the parks we cover, that three-hour window holds the most Banks' Brown sightings with a recorded time, and nearly all of them come between 6 am and 6 pm: it is a daytime animal.
Only Sydney, in our data
Sydney is the only city on Wallace's Line with enough records to rate Banks' Brown sightings: under 5% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Banks' Brown is recorded against all the insects logged in Sydney (5 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.
