Rare
Under 5% of wildlife watchers report a Regal Hairstreak sighting in São Paulo on a given day, based on 8 verified sightings from GBIF citizen-science data. It is the 568th most-seen of the 832 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.
May
In that month about 10% of wildlife watchers report a Regal Hairstreak in São Paulo on a given day, against under 5% in June to April, the lowest months. That is one of São Paulo's driest months, with about 65 mm of rain against 230 mm in January.
Between 9 am and noon
Across all the parks we cover, that three-hour window holds the most Regal Hairstreak sightings with a recorded time, and nearly all of them come between 6 am and 6 pm: it is a daytime animal.
Among the best
Of the 2 cities where we can rate Regal Hairstreak sightings, São Paulo ranks 2nd at under 5%, level with the leaders once rounded. The best odds are in Rio de Janeiro (Brazil, under 5%).
Same family: Lycaenidae

GBIF citizen-science records
It is estimated from how often the Regal Hairstreak is recorded against all the insects logged in São Paulo (8 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.
