Junonia evarete

Junonia evarete (Cramer, 1779), the tropical buckeye or South American tropical buckeye, is a South American butterfly of the nymphalid (Nymphalidae) family. It has characteristic eye spots on the wings, which have a wingspan between 4.5 and 6.5 cm (1.8 and 2.6 in). This butterfly is easily confused with Junonia genoveva, the mangrove buckeye. Not only have the common names mangrove and tropical buckeye been confused, but the butterflies themselves have been sometimes misidentified in past literature because the two species have many variations, subspecies and seasonal forms, which makes them difficult to identify or differentiate. Phylogenetic studies demonstrate the separation of evarete and genoveva, but evidence suggests that subspecies and perhaps more species await their descriptions within this group.
The tropical buckeye is found in tropical and subtropical South America. It inhabits tropical plains, shrub and scrub areas, islands, primary and secondary forests, and urbanized and suburbanized habitats. With a very fast and low flight, the tropical buckeye prefers open and sunny fields. Adults are nectarivores. Males generally stay in the vegetation or on the ground... Wikipedia →

Possible
About 20% of wildlife watchers report a South American Tropical Buckeye sighting in São Luís on a given day, based on 17 verified sightings from GBIF citizen-science data. It is the 26th most-seen of the 93 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
In that month about 40% of wildlife watchers report a South American Tropical Buckeye in São Luís on a given day, against under 5% in January–February, July and September, the lowest months. That is one of São Luís's wettest months, with about 320 mm of rain against 15 mm in October.
Yes
Of the 9 cities where we can rate South American Tropical Buckeye sightings, São Luís has the highest daily chance: about 20%. Next come Recife (Brazil, about 10%) and Porto Alegre (Brazil, about 10%).

GBIF citizen-science records
It is estimated from how often the South American Tropical Buckeye is recorded against all the insects logged in São Luís (17 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.
