Colias lesbia
In 3 days ~50% in a week ~80%
Colias lesbia is a species of butterfly in the family Pieridae. It is found in the Neotropical realm. Specimens from south Brazil, Uruguay and Argentina differ so little that they cannot be separated. This form is in the male dark orange yellow, specimens with violet reflections are not rare; the black-brown distal margin is not sharply defined proximally. The under surface with the exception of the reddish middle of the forewing is vivid yellow with the usual Colias marking. The ground colour of the upper surface in the females is very variable: orange yellow, yellow, yellowish or white with grey dusting; greenish-grey specimens also occur.

Possible
About 20% of wildlife watchers report a Lesbia Clouded Yellow sighting in Rosario on a given day, based on 16 verified sightings from GBIF citizen-science data. It is the 24th most-seen of the 82 insects we can rate there. Over three days the chance rises to about 50%, and over a week to about 80%, if each day is a fresh chance.
March and April
In those months about 30% of wildlife watchers report a Lesbia Clouded Yellow in Rosario on a given day, against under 5% in January and June–September, the lowest months. Those are among Rosario's wettest months, with about 130 mm of rain a month against 20 mm in June.
Between noon and 3 pm
Across all the parks we cover, that three-hour window holds the most Lesbia Clouded Yellow sightings with a recorded time, and nearly all of them come between 6 am and 6 pm: it is a daytime animal.
Yes
Of the 7 cities where we can rate Lesbia Clouded Yellow sightings, Rosario has the highest daily chance: about 20%. Next come Montevideo (Uruguay, about 20%) and Buenos Aires (Argentina, about 10%).
GBIF citizen-science records
It is estimated from how often the Lesbia Clouded Yellow is recorded against all the insects logged in Rosario (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.
