Archaeoprepona demophon, the one-spotted prepona, banded king shoemaker, or demophon shoemaker is a butterfly belonging to the family Nymphalidae. The wingspan reaches about 54–58 millimetres (2.1–2.3 in). The uppersides of the wings are black, with bright pale blue transverse bands. The undersides are pale brown with a clearer band in the middle of the hindwings and several dark small dots on the margins.
The butterfly larva generally feed on plants of the genus Annona (Annonaceae) and on Malpighia glabra (Malpighiaceae). Adults visit rotten fruit or dung. This species can be found in Mexico, Central America, the West Indies, and northern portions of South America.
Archaeoprepona demophon prefers the edges of forest canopy and subcanopy. Wikipedia →

With luck
About 10% of wildlife watchers report a One-Spotted Prepona sighting in Iguazú National Park on a given day, based on 7 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 226th most-seen of the 306 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.

GBIF citizen-science records
It is estimated from how often the One-Spotted Prepona is recorded against all the insects logged in Iguazú National Park (7 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.
