Under 5% of wildlife watchers report a Nacoleia rhoeoalis sighting in Sydney on a given day, based on 16 verified sightings from GBIF citizen-science data. It is the 412th 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.
April
In that month about 10% of wildlife watchers report a Nacoleia rhoeoalis in Sydney on a given day, against under 5% in May to March, the lowest months.

GBIF citizen-science records
It is estimated from how often the Nacoleia rhoeoalis is recorded against all the insects logged in Sydney (16 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.
