With luck
About 10% of wildlife watchers report a Leuce Yellow sighting in Vitória on a given day, based on 6 verified sightings from GBIF citizen-science data. It is the 100th most-seen of the 129 insects we can rate there. Over three days the chance rises to about 20%, and over a week to about 40%, if each day is a fresh chance.
June
In that month about 20% of wildlife watchers report a Leuce Yellow in Vitória on a given day, against under 5% in February–May, July, September and November–December, the lowest months. That is one of Vitória's driest months, with about 50 mm of rain against 200 mm in November.
Between noon and 3 pm
Across all the parks we cover, that three-hour window holds the most Leuce Yellow 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 3 cities where we can rate Leuce Yellow sightings, Vitória ranks 2nd at about 10%, level with the leaders once rounded. The best odds are in Curitiba (Brazil, about 10%).
Same family: Pieridae
The closest relatives of the Leuce Yellow that you can see in Vitória (family Pieridae, Whites, Yellows, and Sulphurs) are Great Southern White (about 20%), Florida White (about 10%) and Felder's White (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Leuce Yellow is recorded against all the insects logged in Vitória (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.
