Junonia evarete
species of insect

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.
Ecology
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 waiting for receptive females, sometimes all day long.
Begin with the source’s own compact description: “Junonia evarete” is species of insect. The dossier treats that line as a proposition to test through Junonia, evarete and species, not as a finished interpretation.
Why this record matters
The phrase “species of insect” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
The date and method of observation matter as much as the stated conclusion, especially where classification or consensus has changed. The source revision retrieved here is dated Jul 25, 2026. The linked authority identifier is Q3020819. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1779.
Scientific names, classifications and consensus can change while older terminology persists in catalogues and historical literature. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
