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 →

About 10% of wildlife watchers report a South American Tropical Buckeye sighting in São Paulo on a given day, based on 99 verified sightings from GBIF citizen-science data. It is the 71st most-seen of the 832 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.
November to May

GBIF citizen-science records
It is estimated from how often the South American Tropical Buckeye is recorded against all the insects logged in São Paulo (99 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.
