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.

Possible
About 20% of wildlife watchers report a Southern Red Rim sighting in Main Ridge Forest Reserve on a given day, based on 9 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 163rd most-seen of the 346 insects we can rate there. Over three days the chance rises to about 40%, and over a week to about 70%, if each day is a fresh chance.
August
In that month about 40% of wildlife watchers report a Southern Red Rim in Main Ridge Forest Reserve on a given day, against under 5% in March–June and September–January, the lowest months.
Between 11 am and 2 pm

GBIF citizen-science records
It is estimated from how often the Southern Red Rim is recorded against all the insects logged in Main Ridge Forest Reserve (9 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.
