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 →

Possible
About 20% of wildlife watchers report a One-Spotted Prepona sighting in Calakmul Biosphere Reserve on a given day, based on 21 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 6th most-seen of the 75 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.
July
In that month about 40% of wildlife watchers report a One-Spotted Prepona in Calakmul Biosphere Reserve on a given day, against under 5% in February, May, October and December, the lowest months.
Between 1 and 4 pm
Across all the parks we cover, that three-hour window holds the most One-Spotted Prepona sightings with a recorded time, and nearly all of them come between 6 am and 6 pm: it is a daytime animal.
Yes
Of the 5 parks where we can rate One-Spotted Prepona sightings, Calakmul Biosphere Reserve has the highest daily chance: about 20%. Next come Iguazú National Park (Argentina, about 10%) and Iguaçu National Park (Brazil, about 10%).
Same genus: Prepona
The closest relatives of the One-Spotted Prepona that you can see in Calakmul Biosphere Reserve (genus Prepona, Preponas and Agrias) are Shaded-Blue Leafwing (about 10%) and Prepona demophoon (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the One-Spotted Prepona is recorded against all the insects logged in Calakmul Biosphere Reserve (21 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.
