With luck
About 10% of wildlife watchers report a Hanno Blue sighting in Niterói on a given day, based on 16 verified sightings from GBIF citizen-science data. It is the 11th most-seen of the 46 insects we can rate there. Over three days the chance rises to about 40%, and over a week to about 60%, if each day is a fresh chance.
June and September
In those months about 30% of wildlife watchers report a Hanno Blue in Niterói on a given day, against under 5% in April, July–August and November–January, the lowest months. Those are among Niterói's driest months, with about 60 mm of rain a month against 230 mm in December.
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.

Same order: Lepidoptera

GBIF citizen-science records
It is estimated from how often the Hanno Blue is recorded against all the insects logged in Niterói (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.
