With luck
About 10% of wildlife watchers report a Hanno Blue sighting in Rio de Janeiro on a given day, based on 12 verified sightings from GBIF citizen-science data. It is the 70th most-seen of the 169 insects we can rate there. Over three days the chance rises to about 20%, and over a week to about 30%, if each day is a fresh chance.
January–March, May–August and October
In those months about 10% of wildlife watchers report a Hanno Blue in Rio de Janeiro on a given day, against under 5% in April, September and November–December, the lowest months.
Between 9 am and noon
Across all the parks we cover, that three-hour window holds the most Hanno Blue sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
15th of 16
Of the 16 cities where we can rate Hanno Blue sightings, Rio de Janeiro ranks 15th at about 10%. The best odds are in Salvador (Brazil, about 30%), São Luís (Brazil, about 30%) and Caracas (Venezuela, about 30%).
GBIF citizen-science records
It is estimated from how often the Hanno Blue is recorded against all the insects logged in Rio de Janeiro (12 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.
