Biblis hyperia, the red rim or crimson-banded black, is a species of brush-footed butterfly (family Nymphalidae) that is native to the lower Rio Grande Valley of Texas in the United States, Mexico, the Caribbean, Central America, and South America as far south as Paraguay. Its genus Biblis is so far monotypic, but at least one other undescribed species is suspected to exist.
They can be seen flying between March and November in subtropical forest. The immature larvae feed on Tragia volubilis. Adults have a velvety-black forewing with a gray hindwing. The hindwing has a pinkish-red band. The caterpillars of this species are gray brown with raised green marks and spikes.

Likely
About 40% of wildlife watchers report a Southern Red Rim sighting in Iguazú National Park on a given day, based on 193 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 8th most-seen of the 306 insects we can rate there. Over three days the chance rises to about 80%, and over a week to over 90%, if each day is a fresh chance.
April–June and September
In those months about 50% of wildlife watchers report a Southern Red Rim in Iguazú National Park on a given day, against about 20% in December, the lowest month.
Between 11 am and 2 pm
Across all the parks we cover, that three-hour window holds the most Southern Red Rim sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Yes
Of the 3 parks where we can rate Southern Red Rim sightings, Iguazú National Park has the highest daily chance: about 40%. Next come Iguaçu National Park (Brazil, about 40%) and Main Ridge Forest Reserve (Trinidad and Tobago, about 20%).
Same order: Lepidoptera
The closest relatives of the Southern Red Rim that you can see in Iguazú National Park (order Lepidoptera, Butterflies and Moths) are Agathina Emperor (about 70%), Hydaspes Eighty-Eight (about 50%) and Orange Mapwing (about 50%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Southern Red Rim is recorded against all the insects logged in Iguazú National Park (193 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.
