Rare
Under 5% of wildlife watchers report a Balta bicolor sighting in Brisbane on a given day, based on 6 verified sightings from GBIF citizen-science data. It is the 914th most-seen of the 1083 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 Balta bicolor in Brisbane on a given day, so our monthly data shows no clear season.
4th of 4
Of the 4 cities where we can rate Balta bicolor sightings, Brisbane ranks 4th at under 5%. The best odds are in Auckland (New Zealand, about 20%), Melbourne (Australia, about 10%) and Sydney (Australia, under 5%).
GBIF citizen-science records
It is estimated from how often the Balta bicolor is recorded against all the insects logged in Brisbane (6 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.
