With luck
About 10% of wildlife watchers report a Juno Silverspot sighting in Rio de Janeiro on a given day, based on 12 verified sightings from GBIF citizen-science data. It is the 66th 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.
April–July and September
In those months about 10% of wildlife watchers report a Juno Silverspot in Rio de Janeiro on a given day, against under 5% in August and October–March, the lowest months. Those are among Rio de Janeiro's driest months, with about 65 mm of rain a month against 230 mm in December.
Between 11 am and 2 pm
Across all the parks we cover, that three-hour window holds the most Juno Silverspot sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
22nd of 24
Of the 24 cities where we can rate Juno Silverspot sightings, Rio de Janeiro ranks 22nd at about 10%. The best odds are in Quito (Ecuador, about 30%), Arequipa (Peru, about 30%) and Puebla (México, about 30%).
GBIF citizen-science records
It is estimated from how often the Juno Silverspot 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.
