Aphrissa statira, the statira sulphur, is a species of Lepidoptera in the family Pieridae. The species is a medium-sized yellow butterfly, with females more pale than males. They are found from southern regions of Florida and Texas through southern Brazil and northern Argentina. The caterpillars feed on the leaves of several local host plants, while adults prefer to feed on the nectar of red or orange colored flowers. The species is most noted for their dramatic migrations in the tropical areas of the Americas. They have been the subject of many studies about how butterflies navigate and orient during migration.
Aphrissa statira has a wingspan of about 2.37 inches (6.0 cm) to 3.12 inches (7.9 cm). Because of their yellow color, they can be difficult to differentiate from cloudless sulphur butterflies when flying. In general, the color of their wings vary between individual butterflies, with the most variation in color seen in Colombia, Central America, and Mexico. The subspecies A. statira cubana has also been characterized in Cuba, Jamaica, and the Cayman Islands. The lustrous underside of the wings of both sexes is pale green or white with more yellow on the edge... Wikipedia →

With luck
About 10% of wildlife watchers report a Statira Sulphur sighting in Calakmul Biosphere Reserve on a given day, based on 5 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 62nd most-seen of the 75 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 and August
In those months about 20% of wildlife watchers report a Statira Sulphur in Calakmul Biosphere Reserve on a given day, against under 5% in July and September–May, the lowest months. Those are among Calakmul Biosphere Reserve's wettest months, with about 110 mm of rain a month against 15 mm in February.
Between noon and 3 pm
Across all the parks we cover, that three-hour window holds the most Statira Sulphur sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
5th of 6
Of the 6 parks where we can rate Statira Sulphur sightings, Calakmul Biosphere Reserve ranks 5th at about 10%. The best odds are in Iguazú National Park (Argentina, about 20%), Iguaçu National Park (Brazil, about 10%) and Lago de Yojoa (Honduras, about 10%).
Same family: Pieridae
The closest relatives of the Statira Sulphur that you can see in Calakmul Biosphere Reserve (family Pieridae, Whites, Yellows, and Sulphurs) are Florida White (about 10%), Lyside Sulphur (about 10%) and Giant White (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Statira Sulphur is recorded against all the insects logged in Calakmul Biosphere Reserve (5 verified sightings from 2019 to 2026), 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.
