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 →

Rare
Under 5% of wildlife watchers report a One-Spotted Prepona sighting in São Paulo on a given day, based on 9 verified sightings from GBIF citizen-science data. It is the 537th most-seen of the 832 insects we can rate there. Over three days the chance rises to about 10%, and over a week to about 20%, if each day is a fresh chance.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a One-Spotted Prepona in São Paulo on a given day, so our monthly data shows no clear season.
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.
Only São Paulo, in our data
São Paulo is the only city on Wallace's Line with enough records to rate One-Spotted Prepona sightings: under 5% of wildlife watchers there report one on a given day.
Same family: Nymphalidae
The closest relatives of the One-Spotted Prepona that you can see in São Paulo (family Nymphalidae, Brush-footed Butterflies) are White Peacock (about 20%), Juno Silverspot (about 20%) and Lansdorf's Crescent (about 20%), 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 São Paulo (9 verified sightings), 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.
